In Many drawings, users need to show holes. Green plastic stencil size: 7. The reason for doing this, is that Freecad will place the solid geometry in relation to the sketch. Because that is what the formula I found on the "internets" said. You bend the legs of the compass so that the distance between the tip of the pencil and the sharp point is the same size as the radius you want. The Radius is the distance from the center outwards.

It's all about give and take, isn't it? Think about it like this: Since every circle is the same shape (uh…round), the only things that distinguish two circles are where they are and how big they are. Say, ([shift=(t:r)] x, y) is the proper starting point, where (x,y) is the center and (t:r) is the polar coordinate of starting point. Use this tool to draw Concentric Circles on a map. Cooler than discs. To do this, create a sketch ("Tasks" tab) and close it. Center Marks for a Radius or Circle If this is your first visit, be sure to check out the FAQ by clicking the link above.
