Okay.
My point list now only shows the points of the polygons, not of the primitives.
But if I implemented primitives, it would just add these points to the list.
When I modify one, these point's wouldn't be affected because - as you said -
you can't change them like that. The program would change all the points of the
polygons but the primitives would stay the same.
My program does not "define" the objects by the points in the point list, it
just reads the file and displays them in the list.
I also added the feature "Use second program", so that you can open the part in
MLCAD etc. and do the changes there, if you like. Then just save it and my
program will automatically update its point list.
I only wanted to create an extended version of the MLCAD part authoring
commands...
I think the bigger problem is a part containing subparts that also contain
subparts. I don't know how to handle this. I could add points of a subpart to
the list (if I knew how to interpret the matrix), but not of sub-subparts or
sub-sub-subparts.
Another possibility would be that I added the primitive points temporarily, so
that they only appear when you really need them. Then I don't have any "dead"
points of former primitive shapes in the list and my program wouldn't have to
remember so many points. Just click on the part and say "Show points!" -
wouödn't that be a solution?
How do LDRAW converter use primitives? I think it'd be quite diffiult to make
the program recognize every scaled and rotated primitive.
You mustn't forget - this is all still a "dream". I did not program any
primitive integration yet. But if we know how to do it, I (or someone else?) can
try to add these features.
