...or you made IDENTICAL components from identical groups or elements, and want to UNIFY them (to have only one definition).
This can't be done changing the definition names, but selecting the components, then right-clicking to the Component you want to switch to, in the Component Browser, and selecting the "replace" command.

The image you posted shows a "triangular subdivision", more than rectangular. This is not important anyway.
Don't know if there is a plugin for this, but it appears simple enough, to do without.
Create a component (a sticky one will be better) with the grid, big enough. Place it on the face and scale to your need (Fredo6 scale, if you want more options). Then select face and component and run the command "intersect selected". Delete component and you are done.

The link to Trim_extend (by RickW) leads to a page where the plugin is NOT available. In fact it seems that it is in nowhere, now.

--Select the COMPONENT you want to replace;
--Go to the Components Browser:
--Right-click on the preview of the replacing component;
--Choose the "Replace selection" command;

Was this your goal?

A simple and safe way, for me, is to select everithing in the zipped file, drag and drop all to the Plugin folder.

Absolutely correct, TT.
Anyway, it is also true that texture placement is mostly done in a inaccurate way. Is there a chance to have some numeric input, for scaling/skewing/rotating textures?

TIG, "thanks" for your reply, and "thanks" for your great and valuable work!

These are:-

What is a material "type"?
I feel I'm missing something basilar, but I can't find this in the "modify material" window.

Maybe someone has to delete the [Plugin] tag from this discussion.

The new one has expired, and now? Is supposed to arrive a new one-year update? or this plugin is dead forever?
