Force Vertical or Horizontal Dimension with LISP

[Bill Tillman]

I've searched for this because I thought I saw it here somewhere before. How can add a dimension using LISP and force it to be vertical or horizontal?

How is dimension added?

If you use (command ... then

(command "DIMLINEAR" p1 p2 "V" p3); or H for horizontal

Using entmake, DXF code 50 is for rotation angle (0 for horizontal and pi/2=1.5708... for vertical dimensions)

Thanks, I have some stubborn dims that won't stay vertical. I use the command method. I've done it with entmake but that creates 20 or so lines of code in lieu of the single line needed for the command method.
