Creating fillets
From Protocase Designer Documentation
In mechanical engineering, a fillet is a rounding of an interior or exterior corner of a part design. In Designer, you can quickly create fillets using the Trim tool on circles. This tutorial shows how to create a slot with filleted corners.
- To make it easier to make the curves match perfectly, set the grid to the size of the radius you want on the curve.
- Draw the rectangle for the slot.
- In each corner, place a circle, using the grid to be precise.
- Click the Edit tool and draw a selection box around the rectangle (which includes the circles).
- Click the Trim tool.
- Zoom in on each circle and erase the outer square line segments and the inner circle arcs to create the fillet.
- The filleted corners are complete.
- Press <Esc> or click the Edit tool to complete the trim.
