Trying to query for edge betwen a loft and an extrude
In featurescape I am trying to add a fillet on an edge between a rocket in and body (loft and extrude). I've manually put in in the fillet, but I would like to do it in featurescript ("TODO" in the feature script). I need form a query to find the edge. I've tried a bunch of things, but no avail. Something like ... var…

Loft guideline trouble
Hey, We have a legacy SW part that needs to be revised. I started to remodel in Onshape but found some lofting trouble. The end result should look like this. Where the big curved inside should really be cylindrical, and transition nicely into the straight side flaps. The curved outer rim is bigger in the middle than on the…

LOFT_SELECT_PROFILES error
I'm trying to create a loft from a defined face to an created point. I always get the error LOFT_SELECT_PROFILES. //Loft var top = (normal * definition.Height) + origin; const vertexID = id + "topVertex"; opPoint(context,vertexID,{point : top}); var topVertex = qCreatedBy(vertexID, EntityType.VERTEX); var profiles =…

How to have a bend on two surfaces?
Hello I am currently working on two rectangular shapes where one is angled to the other by 15 degrees. I just need now to have some sort of bend on each corner to have a smooth connection. I tried to fillet/loft them but it just won't connect as smooth as possible. I am quite new to CAD sorry if this is obvious.…

How to loft an X connection between 4 Struts seamless
I am trying to Loft between 4 Profiles and can't get it work in smooth way, whatever i try breaks some constraints (see below) or creates visible seams instead a smooth surface. https://cad.onshape.com/documents/da3a8c590dc62827f33a5612/w/97ef208146d4363f51be660c/e/3724355a8d2aec9c863e438a Constraints: - All surfaces must…

Loft between top of shell and inclined plane
Im ty to create a set of inclined planes which I would like to join to top of a shell. However, when trying to use a loft it looks crappy as the loft looks like it is using a point on the shell as an unwanted vertices. How do you do this>…

Guide curve or more profiles for lofting.
I am lofting a changing profile P(t) where t is a parameter tmin < t < tmax. I can generate the profile at any t so any number of intermediate profiles are possible. I could also generate the guide curves for the profiles. However is there any benefit to using guide curves if I can just generate more intermediate profiles…

Lofting Trapezoids
I have a prototype 3D shape made from cardboard and tape that I'd like to model for 3D printing. It looks like this (minus the flaps): At first I decided it would be best to start with a side profile and extrude. But it seems problematic with all the angles it has in 3D: So I tried lofting. It wouldn't allow me to create a…

Question re meaning of self-intersecting
Hi, One surface is defined to a sketch plane. The same surface shape, slightly rotated, is defined to a parallel sketch plane. Both surfaces have the same number of vertices and the two surfaces do not share a common axis of rotation. A loft between the two, using matching vertices, does not regenerate properly due to a…

Loft sketches using FeatureScript
Hello, I am trying to build a FeatureScript that will take external data, generate offset sketches and loft them. Each sketch is essentially a profile. However, I am having difficulties creating an array of sketches or profiles to then pass to the opLoft function #N00B. Could anyone take a look at my code? FeatureScript…

Sweep/Loft in 3-D issue..
Hey all, I am trying to create an "s" curved flat surface (model racetrack) I have a 3-D curve, I have profiles where I need them but I cant seem to get it to behave how I want. I can create the loft ne side of the curve will "bank" downward/inward in the correct way, but the other always wants to bank in the…

Loft, using a projected line as guide?
I have been trying to loft a solid surface, I created a projected line to use as a guide but it simply does not work. I have Pierce every profile but it just highlights red. it works when I make a surface loft but the surface is not smooth in between the profiles. does anyone know why this happens? or how to smooth out a…
