Jihwan Choi's picture

Hi, i'm bignnner at OPENCASCADE

i want to develop C# program with OPENCASCADE API

i already installed OPENCASCADE but i don't know what is these api.

perhaps, i think OCCTProxy.dll is OPENCASCADE API. is this right?

I found this at "C:\OpenCASCADE6.9.1-vc10-64\opencascade-6.9.1\samples\CSharp\win64\bin".

Is this right?

Hello Jihwan,

The C# sample of Open CASCADE Technology is just to illustrate the possibility to use OCCT from within a .NET application.

For professional development, we recommend you to consider our Advanced C# Wrapper tool.
