Hi, first experience with SW, and I have a question. Excuse me if it happens I use uncorrect terms, but I try to translate them from italian. SITUATION I have a sketch on a plane (say a simple square, centered on the origin). The sketch is used to extrude for a certain thickness "Th", and with a certain offset "Off" from the plane. QUESTION How can I make reference to "Off" in an equation? PROBLEM What I usually do is: I introduce a quota, select it, click on the sigma symbol, add a new equation, and the quota selected appears in the equation as, for example: "D2@Sketch1" But the quota introduced for the offset is not a real quota, it's only an annotation (it's greyed out), so I cannot set its value to change the properties of the solid. Do I maybe make an error somewhere or is it a limit of the program? Ciao, and thanks for any help, Leodp
