Hi Bavariaboy,
I am not sure if I understood you correctly, but cutting in user defined planes is no problem at all in Dicam:
-You can use the functions 3-4-1 General Cut or 3-4-8 Cut Perpendicular To View
-In the single beam info (middle mouse button), you can click "New", select "Cut off" and enter the parameters for the cut manually.
-You can also use the Smart Tags (3-2-2) to enter a cut off.
Please tell me if I have misunderstood your question.
By the way: The size of Avatars of our users generally does not exceed a size of 120 x 120 pixels. Could you also adapt your Avatar to this size?
Best regards,
Jens
