Resize a object with a fixed profile

mest79 — Sun, 30 Dec 2018 00:52:46 GMT

Hi,
I drawing an arrow with morph tool and save this as a object.
How can I resize proportionally the arrow (A and ZZYZX) without changing the arrow profile?
Thanks

You would have to script it, For starter if You would like to "borrow code" from modelled element, I would use set of beams or walls instead of morph (it is harder to controll geometry of created GDL elements of it).

Do the beams with a complex profile have a different gdl script than the normal ones?

Basically no:

In most cases it will result in some variation of PRISM like commands
I would make it either out of SPRISM (but scripting manually) - You have to check which command is used when saving as GDL - it allows to do ends not perpendicular to the extrude vector, or out of TUBE{2} (the 2nd version allows using profiles... basically allows the holes in the polyshape so the custom profiles can be used)

Wasn't there a resizing object that someone made a few years ago that you could load another object into? Does it still work?

The problem was _not_to_resize_ proportionally the whole object but the "path" only (not the profile).

Starting from version 21 it is possible to associate a "profile" parameter to the objects. it could be a solution?

Yes, see this topic: PROFILES IN GDL.
