I like drawing up arms for racing drones. And I am constantly getting gaps when using tangent's I usually start with two different diameter circles. Then connect them using tangents. I have been drawing designs like this in many other programs with no problems. Trying to do this in ViaCAD is driving me mad. Its my most expensive program that I own, And I struggle with some of the most basic procedures. I have been reading everything possible on these gaps. I can manually fix them. But what a time suck this simple task is giving me. I have the decimals set at 8 digits. Been trying all the repair gaps techniques. zooming in, manually moving the end points, trimming etc.etc. Some times I can get it. But most of the time it is really frustrating. Seems to me that a cad program is supposed to help us draw up our designs. Not just fight us along the way. If anyone out there can clue me in on what I am missing I would be so stoked. I think the gaps and the trim functions in ViaCAD are really tricky. I could just do this step in Turbocad, Moi, designspark, q-cad, or Alibre atom. Wonder if I should be using constraints. This process works so well in Alibre Atom. Just upsets me that I can't figure it out.

can you post a file to figure out your gap issue? Could be just a graphics card issue..
