    <description>&lt;P&gt;YOu can use the command textscr or hit function key F2 to run on or off the text screen.&lt;/P&gt;&lt;P&gt;Select the text you want to copy then use Ctrl C to copy to the clipboard and then Ctrl V to paste it into your response.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I assume you are clicking point #1 when you are prompted for the first point and not typing a t.&amp;nbsp; Only enter the t when you see an option for it.&amp;nbsp; For example, the prompt may look like this:&lt;/P&gt;&lt;P&gt;Enter next point or [end Tangency/toLerance/Undo/Close]:&lt;/P&gt;&lt;P&gt;at this stage of the command you have 5 options&lt;/P&gt;&lt;P&gt;1. enter next point&lt;/P&gt;&lt;P&gt;2.

      <description>&lt;P&gt;Hi. I've been using auto CAD version 2004 (I think it's the Cro-Magon editions since it came out. I continue using it because I can't afford any of the newer editions and it does all that I need. Yesterday I got involved in trying to draw a wingtip of a P 39 aircraft. Since it's neither circular or oval shaped, I tried using the spline drawing tool. I have three known points and am able to draw a spline between them. When I come to the third point and am ready to apply the spline, I'm lost with all the selections I'm presented, close/fit tolerance, start, tangent. The spline looks to be the correct shape but, it is not tangent to the end of the line which represents the leading edge of the wing. The final problem is, I can't finish/apply the spline to the drawing because I just don't know how to do it. Can anybody explain the step-by-step details of how to finish drawing the spline and explain how to use the selections I mentioned above or lead me to a complete tutorial on how to do this?&lt;/P&gt;&lt;P&gt;Thanks. Jim&lt;/P&gt;</description>

      <description>&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Could you post a picture of the wing tip you are trying to draw?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;A good place to start to learn about AutoCAD splines is &lt;A href="https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2016/ENU/AutoCAD-Core/files/GUID-5E7D51E2-1595-4E0C-85F8-2D7CBD166A08-htm.html" target="_blank" rel="noopener"&gt;here&lt;/A&gt;.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;As noted, AutoCAD splines are technically known as &lt;A href="https://en.wikipedia.org/wiki/Non-uniform_rational_B-spline" target="_blank" rel="noopener"&gt;NURBS&lt;/A&gt; Non Uniform Rational B-Splines. This is a fancy name for some fancy math.&amp;nbsp; If you would like to know more about NURBS you can start by learning about &lt;A href="https://en.wikipedia.org/wiki/B%C3%A9zier_curve" target="_blank" rel="noopener"&gt;Bezier&lt;/A&gt; splines and then &lt;A href="https://en.wikipedia.org/wiki/B-spline" target="_blank" rel="noopener"&gt;B-Splines&lt;/A&gt; (which can be considered as a series of Bezier splines head to tail). NURBS are essentially a B-spline divided by a B-spline.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;You don’t need to know any of the math behind NURBS to use them.&amp;nbsp; The key concept is that in AutoCAD there are two methods for creating a spline, &lt;U&gt;fit points&lt;/U&gt; (also know as interpolation points) or &lt;U&gt;control vertices&lt;/U&gt; (CV).&amp;nbsp; Control vertices are the key data element used directly by the NURBS math. Newbies to spline creation will probably use the fit method for creating a spline.&amp;nbsp; The spline will pass through each point you specify in this case.&amp;nbsp; The tangent option lets you specify the slope of the curve at its ends.&amp;nbsp; See the first link above for more detail. Also in that link it states that tolerance&lt;EM&gt; “Specifies the distance by which the spline is allowed to deviate from the specified fit points. A tolerance value of 0 requires the resulting spline to pass directly through the fit points. The tolerance value applies to all fit points except the starting and ending fit points, which always have a tolerance of 0”. &lt;/EM&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If you create a spline using fit points you can drag them around to change the shape of the spline. Here you see&amp;nbsp; a spline with 7 fit points.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ss1.JPG" style="width: 477px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/690695iB5E8493E410A4602/image-size/large?v=v2&amp;amp;px=999" role="button" title="ss1.JPG" alt="ss1.JPG" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;Here the 3rd fit point (from the left) has been moved by selecting and dragging it to a new location.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ss2.JPG" style="width: 479px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/690696i7D15AA1484CE025D/image-size/large?v=v2&amp;amp;px=999" role="button" title="ss2.JPG" alt="ss2.JPG" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;With the properties dialog open you can change the method to Control Vertices and the spline will look like this.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ss3.JPG" style="width: 488px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/690697i00FA867742EB2B4D/image-size/large?v=v2&amp;amp;px=999" role="button" title="ss3.JPG" alt="ss3.JPG" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;In this example, the spline is represented by 9 CVs. The exact number is a function of the number of fit points and the degree of the spline. You can click and drag the CVs like you did the fit points. In the image below the second CV was moved from above the start of the spline to a point directly to the left. The result is that the slope of the spline start out horizontally going to the left.&amp;nbsp; It is useful to know that the second and next to the last CV of a spline controls the slope and radius of curvature at the ends of the spline.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ss4.JPG" style="width: 596px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/690698iA7E87BEB97DDEF0B/image-size/large?v=v2&amp;amp;px=999" role="button" title="ss4.JPG" alt="ss4.JPG" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;The &lt;A href="https://knowledge.autodesk.com/support/autocad/learn-explore/caas/CloudHelp/cloudhelp/2020/ENU/AutoCAD-Core/files/GUID-5530922C-6828-48B1-804C-EDD9053535BD-htm.html?st=splinedit" target="_blank" rel="noopener"&gt;&lt;STRONG&gt;splinedit&lt;/STRONG&gt; &lt;/A&gt;command is a very powerful tool for editing splines.&amp;nbsp; For example, using the &lt;STRONG&gt;E&lt;/STRONG&gt;dit vertex, and &lt;STRONG&gt;A&lt;/STRONG&gt;dd option an additional CV is added to the spline allowing for finer control in that area of the spline.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ss5.JPG" style="width: 610px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/690700i0D9F47425D7D5595/image-size/large?v=v2&amp;amp;px=999" role="button" title="ss5.JPG" alt="ss5.JPG" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;If a cv is dragged to be coincident with another CV the result is a sharp corner.&amp;nbsp; In the following image the newly added CV was moved to the top CV.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="ss6.JPG" style="width: 597px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/690705iE4EED861D117D3B6/image-size/large?v=v2&amp;amp;px=999" role="button" title="ss6.JPG" alt="ss6.JPG" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;In general it is best to use as few fit points (or CVs) as possible.&amp;nbsp; This will help to ensure a smooth shape.&amp;nbsp; An excessive number of fit points (or CVs) increases the likelihood of getting ripples in the curve which are often undesirable.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If you want to create a shape like an airfoil it is a good tactic to use larger distances between fit points where the curvature is slight and closer together where the curvature is tight. You might consider a gradual decrease in spacing as the shape transitions from loose to tight curvature as you can see here.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 589px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/690706i97BCE4CFD64B849C/image-size/large?v=v2&amp;amp;px=999" role="button" title="image.png" alt="image.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I usually start spline creation method by using the fit point method and then use a combination of splinedit and the manipulation of the CVs to get the shape I want.&amp;nbsp; I will also add or delete CVs as needed.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I suggest experimenting with the creation of splines via fit points and CVs and then editing them with splinedit.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Thank you, Leeminardi for the quick reply and all the great information and links it contains. It had to have taken you a great deal of time to compose it. Unfortunately, it doesn't help me with the with the question I should've asked in my first post instead of that rambling one.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;My question is quite simple. When I select the final fit point of my spline, what do I do next to simply finish it and apply it to my drawing? When I look at the spline after selecting the final point, it looks almost exactly like what I want. However, if I hit the enter key, it becomes permanently attached to the drawing but the shape is radically changed. I have attached a drawing describing the problems I am having.&lt;/P&gt;</description>

      <description>&lt;P&gt;Hi jimbir,&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;For your case, it may be best to plot the final control vertex and then re-adjust the previous vertices to fit the curve close to what you were trying to match.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;When drawing NURBS (non-rational uniform b-&lt;EM&gt;splines&lt;/EM&gt;), there is a difference in how the curvature of the spline is calculated based on where the CV (control vertices) are&amp;nbsp;&lt;EM&gt;but also&amp;nbsp;&lt;/EM&gt;whether the CV is the end (sometimes called a knot) of the spline. When you are plotting CVs for a spline, the computer will calculate the curvature of the spline assuming that the next CV you place is not the endpoint. This is because each CV is&amp;nbsp;&lt;EM&gt;weighted&lt;/EM&gt; in a sense based on the two adjacent CVs at least. Imagine if you had a long, thin strip of wood that you had to bend around pegs on pegboard. The curvature of the strip of wood changes depending on whether it is &lt;EM&gt;bent&lt;/EM&gt; around a peg versus whether it is the end of the strip of wood that is &lt;EM&gt;affixed&lt;/EM&gt;.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Leeminardi gave a really great answer that covers the fundamentals of NURBS modelling/drafting. In the context of drafting curvy objects precisely, it will help a lot to take the time to understand some of the quirks of this workflow.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I hope this helps! If I got anything wrong, please correct me.&lt;/P&gt;</description>

      <description>&lt;P&gt;The location of CVs plus the degree of the spline and the weight for the CV determines the precise shape of the NURBS. When creating an AutoCAD spline using the &lt;U&gt;Control Vertices&lt;/U&gt; method the default degree is 3 &amp;nbsp;and the weight of each CV is 1. This applies to the end points as well (they are CVs).&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;When creating a spline with fit points, AutoCAD uses an algorithm to determine the location of CVs. For a 3rd degree NURBS, the 4 CVs adjacent to the spline segment determine its shape.&amp;nbsp; The shape at the start and end of the spline is determined by the first 4 or last 4 CVs.&lt;/P&gt;</description>

      <description>&lt;P&gt;Lee, thank you for the explanation. I ran into a problem when trying to follow it. I created a line at point 1. I followed the instructions in step 2. When I entered the letter T in step 3, I got "invalid point" Followed by the command "select next point". That's as far as I got.&lt;/P&gt;</description>

      <description>&lt;P&gt;Turn off all osnaps and just try to create a spline, as a test,&amp;nbsp; using the method I outlined without any object snaps.&amp;nbsp; This should give you a feel for how tangency works.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Are you getting a prompt "Specify start tangent" after typing T?&amp;nbsp;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Here's the dialog I see when creating the spline.&lt;/P&gt;&lt;PRE&gt;Command: &lt;STRONG&gt;SPLINE&lt;/STRONG&gt;
Current settings: Method=Fit   Knots=Chord
Specify first point or [Method/Knots/Object]:
Enter next point or [start Tangency/toLerance]:&lt;STRONG&gt; t &lt;EM&gt;&lt;FONT color="#FF0000"&gt;space&lt;/FONT&gt;&lt;/EM&gt;&lt;/STRONG&gt;
Specify start tangent:  &lt;FONT color="#FF0000"&gt;&lt;EM&gt;click point to define direction of tangent&lt;/EM&gt;&lt;/FONT&gt;
Enter next point or [start Tangency/toLerance]: &lt;FONT color="#FF0000"&gt;&lt;EM&gt;point  #2&lt;/EM&gt;&lt;/FONT&gt;
Enter next point or [end Tangency/toLerance/Undo]: &lt;FONT color="#FF0000"&gt;&lt;EM&gt;point #3&lt;/EM&gt;&lt;/FONT&gt;
Enter next point or [end Tangency/toLerance/Undo/Close]: t &lt;FONT color="#FF0000"&gt;&lt;EM&gt;space&lt;/EM&gt;&lt;/FONT&gt;
Specify end tangent: &lt;EM&gt;&lt;FONT color="#FF0000"&gt;click point on line but below point #3&lt;/FONT&gt;&lt;/EM&gt;&lt;/PRE&gt;&lt;P&gt;Copy and paste the dialog you see and your actions!&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;I'm not aware of an AutoCAD "version 4".&amp;nbsp; There's a &lt;A href="https://autodesk.blogs.com/between_the_lines/autocad-release-history.html" target="_blank" rel="noopener"&gt;release 4&lt;/A&gt; but that was in 1983.&amp;nbsp; I don't think there was a spline command then as splines were done with polylines.&amp;nbsp; I assume you are using a more recent version than that.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Did you specify the first point as prompted?&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Information regarding my auto CAD version (From the auto CAD help tab)&lt;/P&gt;&lt;P&gt;Product name: Auto CAD 2004&lt;/P&gt;&lt;P&gt;Product release version: 2004.0.0&lt;/P&gt;&lt;P&gt;I don't know the release date although I think it's much later than 83. It has polyline and spline and also some 3-D and solids capabilities.&lt;/P&gt;&lt;P&gt;Yes, I selected the first point in the normal fashion.&lt;/P&gt;&lt;P&gt;I am putting together a chart which shows my action and the resulting entry on the command line.&lt;/P&gt;&lt;P&gt;Is there a way to delete the command history of the drawing?&lt;/P&gt;</description>

      <description>&lt;P&gt;AUtoCAD 2004 is pretty old.&amp;nbsp; The spline command back then may not have had the tangent option.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If not you can get the spline to be tangent by manipulating its Control Vertex polygon as I noted at the end of post #4.&lt;/P&gt;&lt;P&gt;Open the properties dialog box and select the spline. Do you see a Method parameter?&amp;nbsp; If so, change it from Fit to Control Vertices then move the 2nd CV to a point on a line that is the continuation of your original line.&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 390px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/691541iED676FD4B1458743/image-size/large?v=v2&amp;amp;px=999" role="button" title="image.png" alt="image.png" /&gt;&lt;/span&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;I don't see a Method parameter In the properties dialog box.I don't see tangent option however, after I pick a point, I see &amp;lt; start tangent&amp;gt;. My next post will include as much information as I can while trying to draw a spline. It may or may not be helpful.&lt;/P&gt;</description>

      <description>&lt;P&gt;I do not understand why you are reluctant to copy and paste the dialog you see.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;It is difficult to give how-to instructions for a 15 year old version of software I do not have.&lt;/P&gt;&lt;P&gt;Post a copy of the properties dialog box too.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;YOu can use the command textscr or hit function key F2 to run on or off the text screen.&lt;/P&gt;&lt;P&gt;Select the text you want to copy then use Ctrl C to copy to the clipboard and then Ctrl V to paste it into your response.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I assume you are clicking point #1 when you are prompted for the first point and not typing a t.&amp;nbsp; Only enter the t when you see an option for it.&amp;nbsp; For example, the prompt may look like this:&lt;/P&gt;&lt;P&gt;Enter next point or [end Tangency/toLerance/Undo/Close]:&lt;/P&gt;&lt;P&gt;at this stage of the command you have 5 options&lt;/P&gt;&lt;P&gt;1. enter next point&lt;/P&gt;&lt;P&gt;2. T&lt;/P&gt;&lt;P&gt;3. L&lt;/P&gt;&lt;P&gt;4. U&lt;/P&gt;&lt;P&gt;5.C&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;If you see the prompt&amp;nbsp;&lt;STRONG&gt;Enter next point or [end Tangency/toLerance/Undo/Close]&lt;/STRONG&gt; is it at this stage you would enter the T (or t).&lt;/P&gt;&lt;P&gt;If you do not see "end Tangency" then that option was not available in 2014 and you should edit the control vertex polygon&lt;/P&gt;&lt;P&gt;&lt;span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="image.png" style="width: 536px;"&gt;&lt;img src="https://forums.autodesk.com/t5/image/serverpage/image-id/691600i35FF752D7ECECA09/image-size/large?v=v2&amp;amp;px=999" role="button" title="image.png" alt="image.png" /&gt;&lt;/span&gt;&amp;nbsp;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;Thanks for the reply.&lt;/P&gt;&lt;P&gt;Yes I am a selecting Point 1.&lt;/P&gt;&lt;P&gt;I don't see end tangency In any of the prompts.&lt;/P&gt;&lt;P&gt;I don't see the triangular grips when I click on a spline.&lt;/P&gt;&lt;P&gt;The rest of my day is going to be kind of squirrely. I'm going to try to recreate the spline and then work with the textscr command. I'll get back to you later this evening.&lt;BR /&gt;Jim&lt;/P&gt;</description>
