Following François Grégoire's advice in another thread, I've begun learning Tcl.

While ICEM's programmers guide is mentioned as poor in that thread, I'm struggling to find even basic documentation for the basic geometric functions. Some slightly more advanced ones are possible to find (there are descriptions for several "ic_geo_"-prefixed commands).

But specifically, I'm looking for documentation on:

1. ic_point
2. ic_curve
3. ic_surface

The documentation does not seem to have any mention of them.

The way I have been moving forward so far is by recording clicks in the gui. But that seems to also set some default flags that gives me a feeling that others might exist.

E.g.:

• ic_curve is given a list of points - if more than 2 are supplied it makes a bezier-like curve. There might well exist a flag that made it piecewise linear.
• ic_surface, similarly, can take a list of curves, but there might exist a flag that prevents it from modifying the input curves (I've experienced it concatenating some of them - sometimes).

I've tried e.g.

info args ic_surface

But that just returns "args" - not very helpful.

Then I tried:

info body ic_surface

But the procedure body returned seems to be some sort of wrapper that reroutes to

in_ic_surface $args

, which I can't figure out how to access.

So: Does any one here know of alternative documentation channels where these basic commands are documented?
