Hi, gentlemen, I am a beginner, but I successfully draw my first part.\ It looks fine. (It is very "squared", with right angles in the corners). However I meet a viewing problem I dont understand: When I watch the part in "perspective" mode, it appears as it should, (the distances away from the viewer appear shorter), When I switch to the "orthogonal" mode, I expected to see the part without any perspective, as in the so called "isometric" perspective.\ > Instead of this, it appears in a kind of inverted perspective, (the distances away from the viewer appear longer). What did I do wrong? Thanks RV
