Point selection gets wrong points

[snappyjazz]

Hello,

I wrote a program that prints to pdf the window you pick. The window is two promptpointoptions. I should note that in most dwgs, this works; but some drawings the points that get returned aren't what I selected. I copied (and modified) the getwindow code from another post and I can't find it again (go figure). I'm not sure what is different between the dwg's this works on vs the drawings it doesn't work on. I'm not sure what tree to start shaking. Can anyone give me guidance?

I have a couple of comments. 

First you most likely have some code missing. It would be easier to test the code if it came more or less complete. 

Second, now this is my opinion, you have an overuse of namespace abbreviations.  Just import your namespaces; no need to abbreviate everything.  It just makes your code difficult to read and difficult for others to test and debug. If you have that many namespace conflicts then you may want to look to see if you are putting you code in the right spots. (ie, your entire code set is in one file, not good.)

Third, again this is my opinion, you have an overuse of colons. Sometimes the use of colons make sense. Little snippets that can fit on one line of code. Sure use a colon, but not for every single line of code. 

a = 2.3 : b = 6.7 : c = 0.2

Fourth. Your function GetWindow is mixing old style code with new. A try/catch is not needed for creating promptOptions. No need for the result buffers or the arrays of doubles.  See the following refactored  GetWindow function:

Public Function GetWindow() As Extents2d
   Dim ppo As New PromptPointOptions(vbCrLf & "Select First Corner of Plot Area: ")
   Dim ppr As PromptPointResult = ed.GetPoint(ppo)

   If ppr.Status <> PromptStatus.OK Then
      Return New Extents2d() 'Need to then test for zero extents (bad result)
   End If

   Dim pco As New PromptCornerOptions(vbCrLf & "Select second corner of plot area: ", ppr.Value)
   Dim pcr As PromptPointResult = ed.GetCorner(pco)

   If pcr.Status <> PromptStatus.OK Then
      Return New Extents2d 'Need to then test for zero extents (bad result)
   End If

   Dim p1 As New Point2d(ppr.Value.X, ppr.Value.Y)
   Dim p2 As New Point2d(pcr.Value.X, pcr.Value.Y)

   Return New Extents2d(p1, p2)

End Function

It will return an extents2d with 0,0 and 0,0 as the points if the user presses escape. You will want to test for that. 

I think that this is a start and hope that it helps.

Thank you. That did clean up my code. I still have an issue with the wrong points. Although a new development on this is when you don't use a 1st quadrant window. Where if your first point is considered the origin of the quadrant system and your second point isn't in the first quadrant, Acad will use the x coordinate as a horizontal distance to the right, and use the y coordinate as a vertical distance up. I need to figure out how to check which quadrant the 2nd point is in and add/subtract as necessary.

Side note: Is this why other posts ask about converting to World Coordinate System?

Also not sure, maybe this could be a setting? that would make this much easier

Without seeing your full code I wouldn't be able to say one way or another. The PrintObj subroutine definition is not included in the code that you provided.

If WindowCoord = Nothing Then : PlSetVal.SetPlotWindowArea(PlSet, Layout.Limits) : Else : PlSetVal.SetPlotWindowArea(PlSet, WindowCoord) : End If  '<-- Used with Window plot type

---

I am not saying that this is what is causing your issues but this is the first thing that pops out to me. You are testing if windowCoord is nothing. WindowCoord value is an Extends2d which is a Stucture which is a value type and not a reference type like a class is. A value type cannot be nothing. A value type set to nothing would set the values to the default values. 

Does this coincide with your testing?

[snappyjazz · Accepted solution]

I suppose I'm too close to the project and that made sense to me, but to someone else reading the code it is confusing. In the PrintObj - WindowCoord is an optional parameter of the sub. I set the default value for it as nothing. Unless I misunderstand then I should change that "nothing" to a blank extents object, and test for a blank extents as well. I can change that, but adding a converter to the points seems to be working. Its preliminary and I'm still testing.

I have tried changing the WindowCoord default value to a blank extents2d value, but I can't figure out how to. See my failures below.

[hippe013]

Instead of making a structure a optional parameter. Try overloading your sub-routine. 

[Ed.Jobe]

In the first and fourth images, you use 0 when the argument requires a double. Note the message in the fourth image mentions "integer, integer, integer, integer". You can use 0.0 or 0#. I'm not sure that it makes sense to create an extents that is a single point. None of your model would be visible. In the third image, you left off the parenthesis. Should be ..New CadDBS.Extents2d())

Thank you. That did clean up my code. I still have an issue with the wrong points. Although a new development on this is when you don't use a 1st quadrant window. Where if your first point is considered the origin of the quadrant system and your second point isn't in the first quadrant, Acad will use the x coordinate as a horizontal distance to the right, and use the y coordinate as a vertical distance up. I need to figure out how to check which quadrant the 2nd point is in and add/subtract as necessary.

Side note: Is this why other posts ask about converting to World Coordinate System?

Also not sure, maybe this could be a setting? that would make this much easier

---

The quadrants are all included in the same coordinate system, WCS or otherwise. So the answer is NO. The sign of x or y tells you what quadrant you are in. Q1=+x,+y. Q2=-x,+y. Q3=-x,-y. Q4=+x,-y.

I think what is complicating matters is that it appears you are trying to plot from model space. Most of us old timers don't recommend that. That's why paper space was invented for 30+ years ago. Multiple plot areas are just multiple PS layouts. A big bonus is that you can use the PUBLISH command or sheetsets to batch plot. If you specify a plotter and paper size, your plot area is just the Layout. Done. LL is always 0,0 of Q1, btw. You still can specify a window to plot, but that is usually only used when the user wants to just plot a zoomed in area rather than the whole layout.

[snappyjazz]

@hippe013  Thanks I did end up overloading the printobj

@Ed.Jobe Hello, Thanks for helping. I am trying to print from both model space and paper space. The guys here often print specific areas of the drawings for markups and discussion. If I understand your explanation for the quadrants, and correct me if I'm wrong but you're saying that based on what side of the origin your on would tell you what quadrant you're in; and I would agree with you. Our dwg's have the origin set to the bottom left corner (first screenshot), so all of the window selection points are from q1. I'm referring the quadrant that the second window point is from the first window point (see screenshots 2 - 5).  The print window area seems to misinterpret my selection points (see the last couple of screenshots). It seems like it adds the values of the second point to the first point making a different window than what I selected, unless I make a window selection of q1. Does that make sense?

[Ed.Jobe]

In your Select..Case, you start swapping x and y from different points. Naturally, you won't have the same points the user chose. In the picture below, assume that all 4 cases enclose the same area. Pt1 and Pt2 are 2D points. The only variable is the order of selection (the relation of pt1 to pt2) and the only effect it has is to determine whether the window is crossing or non-crossing. It doesn't matter what quadrant the points are in or even if they are in the different quadrants. The selected window will always be the same... until you start swapping x1 for x2. A point is a location in space whose value is determined by the coordinate system. If you don't change coordinate systems in the middle of your command, the results should be consistent. I used Case 1-4, but it could have been Extents2d_1-4.

It might be an interesting extension method to create an IsCrossing property for an Extents.

**Thinking about it a little more..

The constructor for Extents2d is Extents2d.Extents2d (Point2d MinPoint, Point2d MaxPoint)

So it may depend on the definition of the Min/Max. To me the MinPoint has always been LowerLeft and MaxPoint is UpperRight. Someone else can confirm that. So, that represents Case 1 in the picture above. Since Extents2d is only a struct, not a class with some intelligence built into it. I doubt that if you allow case 2-4, then the constructor would interpret those cases. You may have to add some logic to always return MinPoint, MaxPoint to the Extents2d constructor.

[snappyjazz]

@Ed.Jobe Your last paragraph "The constructor for extents2d is...MinPoint has always been LowerLeft and MaxPoint is UpperRight". I didn't know how to describe it that way so I just called it a quadrant 1(haha), I think you explained it better. I think you also gave me confidence in my "points converter" above when you said: "You may have to add some logic to always return MinPoint, MaxPoint to the Extents2d constructor"

You just need to make sure the logic is correct so you don't alter the window location.
