Hi,

In part mode we intially have Front, Right and Top reference planes. Using "Reference geometry >> Plane" I found that I can at least add other reference planes parallel to one of the three primary planes and displace it by a certain distance.

However, if I want to add arbitrary plane that is oblique, for example that has 45° with the front plane and also 45° with the right plane, the plane panel always tells me that "Current combination of references and cnstraints are not valid".

Could anyone tell me how oblique planes can be built?
