Y Axis direction flipped

[SanjivKapila]

I'm trying to create a dissociated copy of dimensions in a 2D view. The recreated vertical dimensions are flipped in direction. Any clues please..

//..

dimLine.MakeBound(0, 1);
XYZ pt1 = GetDimensionStartPoint(dim);
XYZ pt2 = dimLine.GetEndPoint(1);
XYZ direction = pt2.Subtract(pt1).Normalize();

//..

The direction vector is negated for vertical dimensions in the plan view. Please check the attachments..

@jeremytammik Sir! please help..

The purpose of creating Disassociated dimensions is that if something is deleted in a linked element or the file changes, the dimensions referencing linked elements also get deleted. We want to retain the dimensions even if the linked references are deleted.

Yes, I understand the intention. I looked at the code and do not see the problem off-hand. I worked on some tricky dimensioning issues myself for fabrications parts. I believe that some of the dimensions had to be simulated as well in my case. I think it looks as if you have the problem well in hand and recommend further head scratching and debugging to nail the past part. For instance, you can add more information to your output by creating additional elements to mark the orientation of the X, Y and Z axes in the view. Depending on the view direction, I often find that they may be surprisingly and sometimes inexplicably reversed. That is all I can say. Your situation is normal, your problem is standard, debugging and head scratching is your job, not mine.

Thanks Jeremy Sir! 

debugging and head scratching worked for me.

Turns out that

XYZ direction = dimLine.Direction.Normalize(); worked correctly instead of

XYZ direction = pt2.Subtract(pt1).Normalize();
