I think we got you covered, except for the 3 points & ENTER request. But 4 points and no ENTER for a Bezier Curve isn’t terribly bad UX, it works pretty well. And if you need a 3-point Quadradric Curve you can select the same pattern point for the two control points. Again, I hope this meets your needs.
Curves by Length and Angle - Right click in Draw mode and select Options to adjust length and angle in Draw mode, and reverse the curve by swapping the points via the picklists and also swapping your length & angle information.
- ‘Simple Curve’ is for selecting two points to create a curve, ENTER not required.
- ‘Curve Path’ lets you click on as many points as you wish and press ENTER after the last point. I created a curve with 24 points as a test.
Curves by controlpoint - Use pattern points to create controlpoints. RIghtclick in Draw mode and select Options to change controlpoints and reverse the curve via the picklists.
- ‘Curve Tool which uses point as control handle’ accepts 4 points (ENTER not required) to create a Bezier Curve. You can reuse the same point as both controlpoints to create a Quadratic curve.
- ‘Tools for Creating Curves’ takes a minimum of 7 points to create two connected Bezier Curves, and each additional 3 points adds another Bezier curve segment, press ENTER after last point. I created a curve with 31 points as a test.
Also about the curves while creating a Detail piece:
- If you select a counterclockwise curve and don’t press SHIFT the curve will appear as a line in the Detail piece. You can go to Detail mode, right-click on the the Detail piece and rightclick on the curvename and select reverse the curve in the picklist. Click APPLY to see the curve appear. Click OK to save your change.
- If you press SHIFT simultaneously while selecting a counterclockwise curve, it will appear as a curve in the Detail piece.
