Hi everyone, I am a student doing my final yr project. My project involves me to come up with a GUI for this CAD program Opencascade. Currently we can draw using OCC thru TCL command, however this is too user unfriendly thatz y my prof wants me to come up with a GUI to make the control easy. Right now I have the object libraries for all the commands. However I have totally no idea how to go about doing it. Can somebody please guide me on how to go about doing this.
