Is anything grouped? If so, that could play a role in what you select. Sometimes SU just focuses on the overlapping group when selecting something coplanar “underneath”.
Otherwise, if all geometry is in the same context, zoom in and select the circle.
If the adjacent face gets selected too, then hold [Shift] down and subtract the face from the selection (=click on the face with [Shift] down).
Use the ‘Line’ tool and draw over one circle segment per circle (or arc) to see that profiles (thick displayed edges) convert to thin edges that divide separate faces. It takes some redrawing of single segments but will eventually let you select individual faces.
In anycase, I’m guessing you’re going to want to make this board 3D at some point. You’d find it easier to do if you draw the permimeter and extrude it. Then draw the other circles. Except for the small ones around the inner circle, I just use Offset to create the rings. Faces were separated automatically. Crokinole.skp (1.4 MB)
I generally find it useful when working on round things like this to start at the origin. It gives you an easy center point to work from.
You can use Flatten to Plane and FaceFinder plugins. Note that FaceFinder didn’t give decent result at first, so i deleted the problematic face and run the plugin again.
See below .gif for demonstration:
I’m only guessing as I’m on my phone and haven’t looked at the model. But the 1.3/1.4 mb files are too large for the geometry shown and normally this is caused by the dynamic component used in the somewhat pointless 3d printing template. As you know Dave there are 25 pointless components that bloat the template.
It is better to set the number of segments to a multiple of twelve e.g. 12, 24,48,96, etc. and, after clicking for the center, drag along an Axe (Red, Green or Blue) this way, divisions get divided on vertices or (end and mid) points. It keeps SketchUp away from drawing-tiny-edges-problem.
When you draw a circle, type the wanted radius and then draw another one, don’t use offset.
Not in SU. It’s always displayed as a polygon with a number of edge segments specified by the user (default 24).
It has internal ‘metadata’ that so long as the circle isn’t split by being joined to other edges maintains a record of the radius.
So when a SU drawing is exported as a 3D model (but not as 2D), to DWG format (Pro feature) it exports whole circles and arcs as ‘true’ circle objects for AutoCad.
