Looking up the trim tools (in the User Guide PDF, which does not have sections linked to the index, and does not have auto-updating page numbers in the PDF, so not only can't you go to a section from the index, the page number in the index is not the correct page number, so a simple look-up turns into a big search) shows a section almost entirely devoted to curves. I get the impression from this and other things that curves are what TurboCAD is about, that rectilinear 2D objects are not really of much interest here. The various trim functions to not offer an obvious way of creating an object; as I stated earlier 2D objects may not even exist in this app. If I snip and trim and end up with a series of lines that somehow represent a 2d object (though how one indicates whats solid, whats empty etc, in this method is hopelessly complex) the only way to create a 2D object from them is to fill or hatch them. That the object is a fill seems truly bizarre. After all, the fill "region" is a raster, not a vector object, thus won't scale well, and has no flexible properties. So the lines or curves defining it need to remain, and any adjustment must be done to this group (which, I'm beginning to expect can't actually be grouped, without causing other problems) of stray parts, not to the object, AKA: region, that they form, or represent, since no object ever seems to be formed. This all flies in the face of 2D vector design. It appears that moving directly into 3D objects is really the only way to design anything with this version of TurboCAD. Please let me know if my surmises above are true, so I can cut my losses and find a more normal application for the work I need to do.
