Sharp inside corners
You might need a rectangular hole (or any sharp corner shape) into which you will slide a rectangular male item (e.g. a power switch). If you draw a simple rectangle you might receive a warning that the corners will be rounded which could block insertion of the rectangular item. In this case consider creating a shape like this:
You can change the size of he arcs.
To create the above shape:
- Draw a rectangle.
- Draw a circle of the desired corner diameter - say .25". Typically you can use the Minimum Cutter Diameter value.
- Click the Repeat button three times.
- Drag the circles so that their top snap points snap to each corner of the rectangle.
- Rotate each circle around the rectangle's corner the appropriate multiple of 45 degrees.
- Select everything.
- Choose Line | Intersect.
- Delete the interior segments.
- Group the line segments.
- Set Z to Air Inside.
A faster way to do the above is:
To create a mating shape:
- Draw the shape of the male component.
- Select Line | Corner | Mate | Inside.
- Enter the desired radius - it is recommended to use Minimum Cutter Diameter / 2 + .01.
- Click OK.
- Increase the size of the female shape slightly for clearance and tolerance using Line | Contour | Outside.
