Creating objects in TCL script

[SpitForty]

I've just started working with AC3D scripts and have found selection & rotation type functions really useful on objects. But please, how do I make objects - in particular a mesh? The only object creation I've found is a cube, but I'd like to autogen a mesh of various sizes and then select and cut away surfaces.

There are no internal commands to create objects and add vertices and surfaces.

There is an old linecom plugin that comes with AC3D. From Help->about-plugins:

Line command plugin - Version 1.0 by Inivis

This plugin adds internal commands to AC3D.  Commands can be called from outside AC3D using various methods - see the SDK for more info.
commands added are:
line - start a line,
point <x> <y> <z> - add a point to the line
end - finish adding the line

note that you'll need to send the redraw_all command to make AC3D show the line that's been added.

I haven't tried it for a while so it may not still work but if it does, you could possibly use it. If you would like the source code for the plugin, let me know.

Thanks Andy. In the end I found it easier to build a basic mesh, work out the structure of the .ac code and build it outside AC3D. There seems to be a lot of scope for doing things that way.

That's good. You could also use the .tri file format which is really simple - a triangle on each line with an rgb col at the end.

Export something as .tri and have a look in the file to check the format.

Great. Will do thanks
