Technical details on varicad
Hello,
I am in the process of selecting a cad package. I have some questions hope someone can help me.
1 what is the kernel that are used by varicad? What is its advantage over opencascade and parasoid?
2 what is the advantage of opengl vs coin3d? Coin3d is used by another cad software called FreeCAD.
3 what is the advantage of varicad over FreeCAD?
Thank you for your help!

Does varicad support scripting with python?
The advantage of varicad over FreeCAD
The Varicad is more engineering software than Freecad. Especially from mechanical engineering point of view. The Varicad has got
* built in part libraries e.g. DIN, ISO and ANSI screws, profiles, bearings, etc.
* built in symbol libraries for hydraulic, pneumatic and even electrical circuit design
* built in calculation tools for beams, chain and belt drives, springs, keys, etc
* sheet metal flattening tool
Of course the Freecad also has got useful plugins for example the robotic module or ship module (which is really unique), it has got more or less (rather less) working sheetmetal module too, and also are available screws and nuts.
Both of them is running on Linux platform which is advantageous for everybody.
I think the Varicad is better for mechanical design, at least by my experiences.
However the Freecad is a really good tool for visualisation e.g. a plant, a factory or a production line. Because of strong Python interface.
PS: the coin3D uses the openGL. The coin3D is a higher level layer. At the hardver level there are only openGL or Direct3D. As far as I know.
Does varicad support modifying part history
Hello,
Thank you for your reply. I installed a trial version, the interface looks beautiful.

However it seems varicad is a constructive solid modeller, there is not feature history. What should we do if I need to change something back before the current step?
How does the varicad way compared to the sychronous technology by solid edge?
Modifying part history
Hello,
If you need to change something back, you can select entire solids or their components and then e.g. delete or edit it. Also, you can use a function "Solid´s boolean tree editing" - run command "tree".

What is its advantage over opencascade and parasolid?
First of all is the price.
Varicad Answers
1 what is the kernel that are used by varicad?

Varicad has it's own kernel, there is no use of Parasolid, Acis or opencascade.

What is its advantage over opencascade and parasoid?

Varicads kernel is compareble to parasolid or opencascade. The Varicad kernel is really fast and it is stable. Many functionalities are integratet. Wich kernel is better? No Idea. But opencascade is the old Matra Cad kernel wich is not realliy developed in the last years.

2 what is the advantage of opengl vs coin3d? Coin3d is used by another cad software called FreeCAD.

Coin3D is not Opengl, it is the Visualising front end for Cad Software like openscene graph Software. Opengl is the Implementation of 3D functionality und 2D functionality to yout graphics Hardware wich should - for cad use - have OpenGL implementations. Even Coin 3D works with OpenGL as Backend to your Graphic Chip!

3 what is the advantage of varicad over FreeCAD?

Freecad is not ready for work now. You cannot really work in production environment with freecad. It is a gpl Software wich is not professional so there are many functions leaked and a big Set of functions are not working correctly. It is still beta.

Varicad is an engineering Package for 3D Development and 2D drafting. Varicads ability of positioning, moving and generating Parts are full blown professional Features. All Steps of your work will be stored in history Base. You can refuse them lader, change them (i.e. Radius of fillets, Positions of Holes).
