Guys,

 

I'm curious, somebody know how to use the commands: Measure or Divide.

 

I need to distribute a block in one traced line, but with the same space betwen them, these commands put the distance, so, when the object that is the reference got a inclination the distance follow the object but the final distance has a litle mistake because degree of inclination... below I'm showing in some pictures what I'm trying to explain, someone knows one LISP code that can help?

 

Thanks...

Try this quick hack:

 

([color=BLUE]defun[/color] c:mymeasure ( [color=BLUE]/[/color] di en in ln ob p1 p2 sn sp x1 )

               (   ([color=BLUE]=[/color] 7 ([color=BLUE]getvar[/color] 'errno))

This is a nice routine LEE, but how could we replace a 'BLOCKNAME' in lieu of your 'entmake POINT' ?

Thanks.

You're welcome :)

 

Try the following, change the highlighted block name to suit:

   ([color=BLUE]setq[/color] bn [color=MAROON][highlight]"myblock"[/highlight][/color]) [color=GREEN];; Name of block to insert[/color]
