Scaling

Hello I am a student currently taking the course of engineering graphics 1 and it has been a really hard course for me since the beginning but right now I have trouble knowing what scale( 1:1 , 1'-0") and type ( architectural) to use , because I have to make some pieces ( HW #3 Intoduction to AutoCad file below ) and I need to print them out in Sheet Size A( 8.50" x 11" , landscape form) and when I go to the layouts my piece looks really small ( Special Cam. dwg file below) and I have no idea of how to adjust the layouts, when I print how do I make sure its gonna be on the correct scale and that is going to be on the size that it has to  or even what scale to use, if somebody could help thank you from the bottom of my heart and thank you for reading this have a good day !

1. Make sure UNITS is set to Architectural

2. Draw the part in Model Space. This environment thinks you are creating your objects at full size, which is 1:1 scale. I think the PDF shows the dimensions in inches. For example, you have two small holes that are 5.62" apart from each other in the x-axis. You can start with two lines - one starting at 0,0 and going 6 or more inches to the right, and the other starting at 0,0 and going straight up along the y-axis for about 2 inches or more.

 

3. 0,0 is where the first small hole is, so you can draw that by entering C on the keyboard, clicking on 0,0, typing in D (for the diameter option), then entering .62 (the diameter of the circle). If you copy that 5.62 to the right on the x-axis, then move it 1.75 up on the y-axis, that's the locations of the two small holes.

 

4. You can now draw two circles of .75 radius, one for each small circle. You can also offset the 2 straight lines to make the centers of the circles and to find the center of the large circle and hexagon near the middle of the object. You can create a multiline 1.75 wide going from the center of the big circle straight up, and then draw a 6-sided polygon using the same center. Try Inscribed first and Circumscribed to find which one fits the same 1.75 width. It will be straight up, but then you can rotate it the 15 degrees. 

 

5. You can now draw the 1.75 radius circle centered on the big circle. I see two straight lines drawn tangent to tangent. I see two more circles drawn tangent-tangent-radius. What you have now are a bunch of lines and circles. You'll have to use the BREAK command on the circles and then trim/extend as necessary to clean it all up. a word of caution here is that I don't know whether your instructor would agree with my approach. It is important that you follow the steps your instructor required in previous lessons. They may want you to draw construction lines on a no-plot layer, but keep them so he or she could see how you accomplished your work. They may require you to construct this with arcs instead of circles. It is important to understand absolute/relative/polar coordinates, direct distance entry, ORTHO and POLAR settings, and how to watch the command line for options available for the commands. You might also be required to have Object Snap Tracking turned on. I don't even know if you have learned how to set up and place centermarks or centerlines yet. Are you required to dimension this project?

 

6. Now you can set up your output, which is done on one of your Layout tabs. I am sure your instructor would have allowed you to create both portrait and landscape A-sheet tabs in a template drawing, which should be the basis for all of your assignments. This would also have your titleblocks with required text sizes and styles, hopefully already in the right places. Anyway, this is also where you would create the viewport that looks at your model. The viewport is in the layout tab (paper space), but it's like a monitor, where you are viewing what's in model space. if you double-click inside the viewport to activate it, you should be able to zoom to extents (if the viewport is unlocked), then zoom by window to get close to the model, then use the scale list to pick 1:1. The final steps are to pan the view (to center the model) and to lock the viewport (so you can't accidentally change the view scale).

 

I have assumed you know enough that I don't have to explain how to pan and zoom, or how to lock the viewport or choose view scales. One important thing though should be to go into the model space tab and set CANNOSCALE to 1:1. It doesn't affect the fact that you draw in 1:1 scale, but in the future you may see how it affects how you view your linework and other things in model space.

 

Good luck with your assignment, and let us know how it turns out!

 

 

If by some odd chance my nattering was useful -- that's great, glad to help. But if it actually solved your issue, then please mark my solution as accepted :cara_con_una_leve_sonrisa:

Thank you so much and yes we are required to do the construction lines and dimensions

HI @yan.aquino,

 

I see that you are visiting as a new member to the AutoCAD forum. Welcome to the Autodesk Community!

 

I see that @Bob_Zurunkle gave you some excellent suggestions to get you started on the right foot.

 

I made a quick video that shows how to check your units. I like to set the display accuracy a bit higher and show how you can still set the dimensions to only show a limited accuracy.

 

I also put a dimension in your model to show how the objects are 4*" apart.  This means you will need to change the scale of your viewport.

 

I like to apply a page setup for my layout so I don't have to set up plot settings all the time.  You will see that I select a print driver, plot style table and a paper size and that I will plot the paper at 1:1. (1"=1" 1 foot= 1 foot)

 

Next I open the viewport view of your model by double-clicking in it. Now I can select the scale from the scale list.

 

I hope this helps you to work through your class exercise.  Please add additional posts if you need anything more.

Thank you so much but now I have a problem with choosing my scale because when I choose the scale I want to use and then insert my frame in the drawing the lengths of the lines done on the new drawing with the new scale are equal to the ones of the frame. I need to make each one of this pieces and put them in the frame with the dimensions and all but I am having trouble knowing what scale to use so it fits on the frame and what happens with the frame. ( the frame is black so it may be hard to see be careful it's origin is 0,0,0 ) ( also when I go to insert the frame on the block unit says millimeters but I draw it in inches) (also I don't know if it is because I'm inserting the file incorrectly )Frame autodesk .jpg

sorry this file was supposed to be on the other post, this is the file where the lines made with the new scale( 2:1 ) were made but are equal to the ones made with the other scale(1:1) ( remember to turn off the different layers so you can see the difference) ( Frame made with the magenta and the black colors new line made with white) ( grip and spacing set to 1/2") Thank you for everything

I think it was because I had it open on Auto Cad

Hi @yan.aquino,

 

I am only looking at this very quickly so forgive me if I am short with my response.  I moved your titleblock to paperspace and applied a page setup to make it a letter size at 1:1.  Then I created a viewport.

 

Inside model space I inserted your cam.  I switched back to paperspace, double-clicked in the viewport and set the scale at 1:1. Then I used Zoom and entered .2 (20%).  I hope this is what you are looking for.
