trans from paper to get world model space

[kpennell]

It seems, the coordinates I get returned from using (trans (trans 3 2) 2 0), is dependent on the viewdir and viewtwist values of the viewport.

if the viewport is in plan view, looking down, with world X direction to the right, I get the expected values.

If the viewport is looking up, with world X direction to the right, my Y value is equally opposite (+/-) of what it really is in model space.

If the viewport is looking down, with world X direction to down, my X and Y values are swapped.

Any insight?  I'd rather not enter the viewport to retrieve the point using 'getpoint'.  The drawings are rather large, and entering and exiting the viewport is time consuming.  But if I have to, I guess I have to.

Hello, kpennell!

Try the command CHSPACE. Enter a viewport then initiate the command to pull to PaperSpace. AutoCAD will recognize the VP scale and adjust. Similarly, starting in PaperSpace, you can run the command to 'push' to ModelSpace. Try drawing a grid in paperspace then pushing it to ModelSpace to see where it lines up. I hope this helps!

Here's a file since before there was an Autodesk CHGSPACE command.

Unless it's missing some functions I didn't transfer into the freeware version attached, there may be some learning you can get from it.  Please let me know.
