Hi, welcome yto the forum.

What I am missing is how to use the .stl files properly. import() just
loads my mesh data. But I want to have a handle to these vertexes there
and manipulate them. The usage to rotate([...]) import("somefile.stl"); is
just not what I need in the case.

Can't do that.
There has been lots of discussion re this, but no sorry.

Also I am wondering are there mouse events that can click on specific
point of the mesh, to let's say add some points or objects on the mesh?

Not your lucky day here either...
OpenSCAD is a programming language, not an interactive modeller. It is its
specialty, if you want that, there are other products.

Ah... :( I am really out of options... So any suggestions how can I achieve
these with something other than than OpenSCAD?

I'm not a whiz at Blender, barely able to get stuff on the editor screen, but
your description appears to be a good match for the program. One can select
faces, edges or vertices and manipulate them in so many different ways,
including adding new faces, edges, vertices.

I believe that one can also create scripts within blender to accomplish
tasks. I cannot say with certainty that that feature would meet your
requirements and I would not expect Blender to be as parametric-friendly as
OpenSCAD, but I could be incorrect.

Blender is free and has a rather challenging learning curve.

On the question of manipulating vertices of imported models, see this
for some ideas
http://forum.openscad.org/flattening-curved-surfaces-td19727.html#a19739

I still have not released that code, but I am working on it on and off.

Blender is a fine program and does a great deal. For this task you may be
better starting off with Wings3D which generates watertight printable models
by definition (assuming you don't load some junk in to start with but create
the model starting with their primitives).

YMMV but the trick to learnign wings3D is to keep your eye on the status
line as all commands are context sensitive. do a couple of youtube tuts and
you'll get the hang of it.

Hello,

I am quite new with OpenSCAD. I am also debugging it with qtcreator to see
what is going on and where the imported mesh data is and how to catch these
vertices. I intend to make some custom tools to get me started so I will
also share it, but the project is big and I am doing it for 2 days not
intensively, but if I got some progress, I`ll share it.

Hello,

Yes I am debugging it. This night I've found a file import.cc and placed a
breakpoint in /line 67/ . the class is ImportModule I think I am starting
from there to see how can I get some handle to these pixels or data. I may
try to dig in OpenGL also. But will report here if I have some progress.

Regards,
И.Z.

I've been debugging this night, I was able to detect something that can be
helpful for developers: <p/>
*const Geometry PrimitiveNode::createGeometry() const in * primitives.cc *
If somebody could give me a hand debug the OpenSCAD we can work on
something.

Regards.
