multiple 3d-Windows...

Question

Hi there! I would like to create a cad like application with multiple 3d-windows (4) like they are known from 3d-Programs like 3dsmax, maya or whatever. using the standard splittercontrol doesn´t really give me what I want (eg. no draghandle in the middle). I found a good mfc example (enhanced splitter window - from codejock) but I would like to use c# and windows forms. anybody got an idea on how i can solve my problem? any examples? Thanks, ras
