Reference snap to ring, donut...

Post by jancarel » Wed Oct 07, 2015 12:24 pm

I am using Qcad Pro 3.11, Linux 32bit. I am trying to create a printed circuit board layout. The newly added feature Draw-Ring is verry helpful. Using Snap Reference I can only snap to two points on the X axis. How can I snap to the two reference points on the Y axis?

Hi jancarel,

This tool is also new to me but I have to confirm that your experience is correct. Snapping to the top or bottom Y Reference points is impossible without exploding the ring. :cry:

If you create a new ring you can use the reference point option to place your Ring precisely to a x or y connections.

I think you should file a bug report / feature request in the QCAD bugtracker .... :wink:

As you might have noticed, a ring is in fact a polyline with two vertices. The two reference points are the two vertices of the polyline. A possible solution could be to add reference points to all middle points of arcs as well.

Thanks Andrew, this is the solution. Snap to endpoint for left/right and Snap to middle for top/bottom. This works well...

And thank you for Qcad, a great program...

Yes, that should work, good point. Auto snap should also work if it's configured to snap to end and middle points.

Hi Husky,

Thanks for your thoughts. Now that I know that the ring is made out of two halves, I can use Snap End for left/right and Snap Middle for top/bottom. This works fine. For me there is no need to file a Bug Report...
