Tolerance for Boolean Add Along Surface Edges?
Is there an accepted way to compare two surface edges to see if they are within tolerance for a boolean add operation? I'm trying to create an approximate offset curve along a surface - within tolerance - so it can be used for trimming and other operations. In this image the input curve is an isoparam (degree-3) and the…

How to make loft follow guidelines on edge?
Hi there, I'm trying to make an F-35, but have some issues with the front portion. I've created a loft, and added guidelines using 3D fit splines which go from vertex to vertex. However, when I add this as a guideline to the loft, it doesn't touch the curve at all! Additionally, when I pierce the curve, and connect a…

How to Add a Curved Extrusion to a Projected Sketch on a Cylinder?
Hi everyone, I’m currently modeling my NovoPen 6 insulin pen in Onshape and could use some help with a specific feature. I’ve projected a 2D sketch onto the side of a cylindrical surface, and now I’d like to turn that shape into a smooth, curved bump something like a domed or organically contoured protrusion, not just a…

a way to make an exponential curving helix
Hello, I am trying to creat a cam cut in a spherical surface. It works fine using the helix tool and sweep the shape. However I need the curve to have an variable angle where it increases exponential. I found a workaround to create a sketch with the curve as I want it and wrap that over the surface and cut it out. than use…

Custom Feature: Clone Curve to Points
Allows you to move or copy a 3D curve to a new location by defining the new endpoints. New curve retains the essential "Character" of the original curve but is stretched parallel to new Chord to reach target points. (Chord is a line between curve endpoints) User can also scale new curve normal to new Chord, and rotate new…

Point form percentage curve or distance from end
Is there a feature that allows you to place a point on a curve a specified percentage (or distance) from either end?

opBoolean on Surface Bodies
I'm playing around with a new FS for generating reference points from various inputs. One the potential inputs is 3 surfaces or planes. The first step to getting the point intersection between 3 bodies is to generate a robust curve intersection between 2 bodies. This seems to work well enough for simple cases where 2…

Get Edge/Curve Parameters?
Unless I'm missing something, it seems it's currently not possible with FeatureScript to extract the control points, knots, weights, etc. of an existing edge or curve. It really seems like a fundamental problem. Is this on the roadmap? I do see opSplineThroughEdges in the documentation, but it sounds like it's…

to create intersection lines
I often need to create an axis on the intersection of two planes.To do so, is it necessary to create a sketch and a line in the sketch, or is it possible to just select the planes and say "create construction line" and you get a kind of "3D rectilinear curve"? And same question for an intersection curve. Is it possible to…

Edge length of evaluated face?
I'm trying to measure the boundary edge of an evaluated face. When using evFaceTangentPlane, if the face is not square, the evaluation will project where the face should be. I can place a plane on the invisible edge shown below with evFaceTangentPlane. However, I'm not sure how to get the length of the invisible edge. If I…

How do you make a curved ramp?
I am trying to make a ramp above a semicircle that curves along its edge. I have spent the last several hours trying to figure this out so any help would be much appreciated! thanks!
