Invalid flat pattern projection of cones with large top angle
Symptoms
A user wrote: "Two adjacent cones with the same diameter do not fit. For example:
Cone 1:
Diameter 1: 1mm, 0 deg
Length: 10mm
Diameter 2: 12mm, 0 deg
Cone 2:
Diameter 1: 12mm, 0 deg
Length: 30mm
Diameter 2: 24mm, 0 deg
Print both, cut out very carefully, roll, tape together. Result: Cone 2 dia 1 was always slightly larger than cone 1 dia 2 (up to 1mm difference)."
Cause
For cones with a relatively large top angle, the flat pattern projection was inaccurate.
Solution / workaround
This problem is fixed in Cone Layout version 1.2 by changing the flat pattern projection algorithm. Please download this new version if you are experiencing the problem above.
