Loft Twisting
I'm struggling with lofting from a big rectangle to a smaller one. Seems no matter which verticies I match, even though they both have 4 segments, I get this twisting effect, like the segments don't line up. Any ideas what I'm doing wrong here? Doc is…

Exponential horn along spline or collection of edges
Hi. I am trying to create a model of a back loaded horn speaker. This basically means calculating a horn shape according to parameters for the speaker and then try to fold this horn in order for it to fit inside a reasonably sized box. Traditionally this has meant producing cases looking like this: But since more and more…

Connect 2 parts
Any ideas on how to connect the blue and yellow pieces in this img? I can't move any of the gray peices. Doc @ https://cad.onshape.com/documents/14f3d01d62b5237f728896c5/w/40e0afc950b8ca0dfecf9ef8/e/46f1a37d37836942cf49590e I can thicken the yellow or blue parts as much as needed so long as they don't overlap the gray…

Outer Shell fail
I'm trying to outer shell a duct, but it fails. I think it's because some regions are too small, but I'm not sure how to fix this. Link to the doc is @ https://cad.onshape.com/documents/14f3d01d62b5237f728896c5/w/40e0afc950b8ca0dfecf9ef8/e/8c473ae13c752e424f8b5051. I can do an inner shell just fine, but then it blocks the…

Using end conditions within the loft command
Is there a way to get the surface loft commend to use both end conditions and guide rails at the same time, or am I missing the boat on this one?

Loft guides creation?
I'm having trouble understanding the order in which to create features in order to get a good, controllable loft. How do you create loft guides between two points? I've tried creating the loft, then creating a plane from the angled loft, and using that to sketch guides. But I can't use the guides I then create because I…

Loft from a non planar surface
Is it possible to loft from a non planar surface ? I wish to loft from a circle that has been projected up to the curved surface in the image below, is this possible ?

merging and hollowing two lofts
Hi All I'm trying to model and 2-into-1 exhaust collector, and I've managed to create the shape I need, but I can't work out how to hollow it. My part is here. I've tried using shell, and in the top and bottom circles, creating an inner circle and then trying to loft-remove between them, but I'm failing. I need a constant…

To Merge Extrude or not to Merge
Would other users find it useful if "Extrude" type functions were merged? This would give you the option / advantage of toggling between a related but different feature functions without having to suppress / delete and add the other feature as necessary. For example if you chose "Extrude with draft" then at a later stage…

3D splines can't be extruded or lofted
It seems that 3D splines created in FeatureScript can not be extruded or lofted to create solids with them. When drawing closed curves with opFitSpline I can't even select them in the Extrude command. I am doing something wrong?

Why are my lofts failing???
Yes, another loft question. The document my question refers to is this one. Opening this document, you'll find 2 failing Loft features. The first one is named FailingSurfaceLoft. I can get this loft to not fail by removing the two guides that refer to edges in Sketch3. Of course, in so doing I'm left with a loft that…

Loft troubleshooting
Hi, I'm trying to add a rib in a spot with nothing is square to each other, the only way I can think of is running a loft. When I try however I can't get it to solve. The 2 profiles are just 4 sided faces. What am I doing wrong? seems simple enough.. if anyone has a better idea of how to do this I'm all ears. I've even…

Having trouble with a loft/sweep function and cannot figure it out.
Hi All! I'm looking to sweep or loft this profile but it keeps giving me an error. I'm using the faces of sketches 16 and 17 as the profiles and sketch 18 as the guide. I teach CAD at a HS in NJ and one of my students is trying to replicate the item in this…

Loft Assigning crazy vertices
I am trying to make an adapter from odd shape to a circle for intake. It is working sort of. The loft tool is doing weird things with vertices assignment and when I try to force them it won't make the loft at all https://cad.onshape.com/documents/a6e93af4fd864488a53738d9/w/b53d4986f3dc48e2b72b4a19 If you remove the…

Connect Extrude to Spline Revolve (with a Loft)
Hi, probably a newbie question but I'm stuck and the search did not help either... I have a kind of bowl I created from a spline that I revolved and thinckened afterwards. In this bowl there is a vertical platform that was created by simply drawing a rectangle at the bottom and extruding it. Now, what I really need is the…

United Lofted Parts?
Hi all! First time asking something here. Here's my part link for reference: https://cad.onshape.com/documents/a3d584c5c8704fd59e6d1baa/w/8f543b70179b4f319bb33b46/e/debd8ae843674bf3a80aef15 This is just some jar I'm making for fun using the loft command, and possibly 3D Printing later. I lofted a single rib and then…

Joining 2 points across a perpendicular plane
I created 2 semi circles on two parallel planes that are offset from eachother. I then created another plane across the flat sides of the Semi circles and im trying to sketch 2 lines from the outer points of the semi circles down that perpendicular plane. but the tool wont snap to the outer points, it will only snap to the…

Creating a loft feature
How do I create loft feature in Onshape? I have attached a picture showing a loft feature in conventional CAD, how do I replicate it in Onshape?

Reuse a previous feature to make another Part, a "lost" tool in a Boolean-Merge for example?!
I did locate the Loft that created my "lost" tool part used in a Boolean-Merge. What if there was a "Use" or "Recreate" option in this menu??? Then I could make a new Part using Loft 1 without a lot of hassle!

Loft
Hi all, I've been fiddling with the loft feature and having some issues. Below is a pic of the part i'm working on. The issue is that I get a "guide curve" that I don't want (straight line between the sketches) I've seen this with different CAD systems too and usually the added guide curves are enough to get rid of it. Any…
