Bad Math in Double Block Insertion

[mjshaffer117]

Hello!

I'm working on editing a LISP routine that will insert a block in paper space (elevation marker) and a separate block in model space (antenna block) given a selected pre-drawn horizontal line in paper space through a viewport. The problem I'm having is that the antenna block insertion through the viewport (the antenna) does not come in at the user entered value, I'm pretty sure the math is incorrect in the code but I can't figure out what the math should be to obtain the correct value.

The problematic area is highlighted with 6 semicolons.

Any info and feedback is greatly appreciated!

@mjshaffer117  hi,

Post a sample dwg + all the missing functions.

If the model has say a UCS set that is rotated I found I had to do a double trans to reflect the world co-ordinate in pspace. So would go mspace insert block then pspace insert block. Please note also if you have multiple viewports it can get confused to where it is when swapping.

(command "Mspace")
(command "UCS" "w")
(setq psnewcen (trans (trans newcen 1 2) 2 3))

Thought of a quick and dirty if you use CHspace for the block in mspace to pspace get insertion point, erase the block, insert second block.

[mjshaffer117]

Thanks @Sea-Haven,

I thought about going the chspace route as well, I ran into an issue where the viewport is going to always have to adjust based on the height of the object in model space that the blocks are going to be inserted on so I think chspace may actually be a better solution for the future progress of this piece. Unless I can figure out how to save the scale of the viewport in a variable and do some funky math with it to get the insertion points in paper space and model space to line up! Right now this LISP only works if the scale is at 1:30, still trying to figure out how to make it work for any scale 🤔

[mjshaffer117]

@Moshe-A  Hello!

Since this post the code has changed rather significantly, I was able to get it to work properly but only in a 1" = 30'-0" scale by dividing the "offset" variable by 30. I'll resend the updated code and a drawing to better show how this is supposed to look. The initial problem I was running into was that the model space blocks kept coming in relative to 0,0,0 location in model space, so they were off by about 33' in comparison to the elevation markers in paperspace. That so far seems to have been resolved.

The idea is to automate our drawings to insert an elevation marker in paper space and an antenna block location in model space at a user specified location. The trouble I'm having now is trying to make it so that this code will work for any viewport scale and not just the 1" = 30'-0" scale.

[Sea-Haven]

I did not wade trough the code this may be useful re scale.

; obj is a viewport

(setq  cen (vlax-get obj  'Center ))
(setq ht (vlax-get obj 'Height))
(setq wid  (vlax-get obj 'Width))
(setq sc (vlax-get obj 'customscale ))
(setq ang (vlax-get obj 'TwistAngle))
