I have an assembly, in which I'm trying to do a sketch in order to obtain some dimensions for another part I will insert back into the assembly. However, when I try to sketch in the assembly, the endpoints of the arcs/lines I am drawing are always offset and behaving funky. For example, the endpoint of the line (circled in red) I am showing in the image below is offset. And when I try to click the endpoint, I am not able to select it by hovering my mouse over it. Maybe this is a performance issue with my computer. If it is, is there any setting in SolidWorks I can use to help alleviate this problem? Thank you.
