Hi,
I am creating a Lisp routine to generate 3D cylindrical tanks.
I have a problem when i use the command "_pline" in an isometric view. The pline' command generates a 2D sketch that does not match the calculated vertices coordinates. The result looks random, especially when there are arcs in the sketch's pline (to draw torispherical heads, ellipsoidal heads, dished bottoms for example).
The basic principle to generate the 3D solid:
- I calculate the XY coordinates of my sketch' vertices (based on main tank's dimensions and standard),
- I Draw a sketch,
- Then i Rotate the sketch 360° round Z axys to get a 3D solid,
The problem seems to occur only when model space is in isometric view. Everything works fine when in ortho view. Is there something i should know about plines that contains arcs when i'm in an iso view mode ?
