Hello,

I want to create a CAD app but I dont know which Lazarus compatibile
graphic engine is better for this task.
In the begining just 3D line, circle, arc etc. later a want to use
also 3D solids.

             GlScene
             Kambi
             TOpenGl component

Let me know if you know something else suitable for this task.

Or is there a possibility to use Blender with Lazarus?

Thanks

Kambi is actually a game engine, so you probably don't want to use it
since it would give big overhead. GLScene is powerful (it has a lot of
components and you can see them at design time) but it's kinda heavy,
no problem if your computer has a plenty of RAM and quite good
processor. TOpenGLContext is a plain component (say... a canvas) that
allows you to write any OpenGL thing in it. Nothing more.

If your going to do a cad program then your going to want a vector
graphics library.
Heres two good ones.....
http://code.google.com/p/luipack/source/browse/trunk/cairo/
or in the lazarus directory in components look for aggpas.
Ive never used either of these pascal implementations but I can tell
you their both based on two very good library's for this task, cairo
and antigrain...

components based on it - a good choice
