removing curved lines using FPRISM

Anonymous — Thu, 23 Jun 2011 18:58:48 GMT

I am starting the GDL scripting. I created a square column and everything is good, except I cannot make the arc line not visible. I used the FPRISM command, like what is shown in the GDL reference guide (pg. 46) to build the cap piece. I used 2 FRRISMs for the band piece. What I am wanting to do is remove the lines in the curved areas. Here is the code that I used for the cap piece (I used parameters for the distances).

MULZ -1
RESOL 18
FPRISM_ column_material, column_material, column_material, column_material,
4, thickness_cap, 0, radius_cap,
0, 0, 15,
length_cap, 0, 15,
length_cap, length_cap, 15,
0, length_cap, 15

FPRIM_ is limited in that you cannot remove these lines.

As an alternative try using an extrude command (or PRISM_, or ....) with a cutting plane on either end to create the miter. You can then use a loop to create multiple copies and rotate them into position about your column.

Of course with this method, you will have move movement to rotate and get the parts into position first, but there won't be any lines.

That's where HPRISM comes to the rescue.

Why not just TUBE command for this?

The tube command works quite well. However, at least in AC 12, it has a rendering problem. Perhaps that has been fixed in later versions.
