I had a bit of a disaster on a project recently. The source of the problem was that in creating a notch for some bent plywood to sit in, I’d used
Offset Curve on the output of a previous
- Blue is the original curve.
- White is the original curve offset 0.125 units
- Red is the error, which is an offset of the white curve of 0.335 units, creating a non-arc that made my notch too tight.
- green is the desired result, achieved by a single offset of 0.46 units.
Is this an error that happens only in certain circumstances? The original curve here is a polycurve comrised of arcs and lines.
Do I need to make sure all my offsets are done from the original curve using addition, rather than successive offsets in order to avoid this problem?
Why did this happen?
Attached, for reference, is the definition, which was intended to quickly make polycurves into CNC routed pedestals, with markups pointing at the good and bad offsets. Curve+Straight Pedestal Maker.gh (72.9 KB)
