  • This app hasn’t received enough ratings or reviews to display an overview.

• Cone, cylinder and elbow development is now part of Pro. The drawing stays free to try; bending calculations stay free. • Free users see a small banner on the home screen and, now and then, a full-screen ad before a pattern opens. Pro removes both. • The yearly plan shows its monthly price, and a purchase that does not go through now says why.
