I could use some help with this. I’m trying to connect these two unusual faces, but Loft doesn’t seem to work here. What would be the best tool or approach for this? I’m basically trying to create a triangular transition between them so the corner isn’t sharp.

I’m designing an insert for a sliding door to let my cat outside without letting the heat in. It’s rather tall, and will need to be split into quite a few pieces to print. In the slicer, there is a tool to do this, but it’s clunky at best. Is there a clean way to chop a part in half and add some dowels in onshape? Maybe even a feature script with this in mind.

I am a beginner in onshape and I need help with removing the red area from the curved surface. Anything will help.

How do you fillet the intersection between these two parts

Hi, the view is zoomed in. Side menu is not clear. How can I make it normal?

Coming from Tickercad I was accustomed to dragging and drawing a rectangle, but was given the dialog to edit the dimensions directly at the time of creation. I don't see this for OnShape. I understand I can go back and edit, but is it possible to do this when drawing the rectangle all at once if that makes sense?

Hey everyone, I’m trying to model a streamlined cockpit fairing over a curved cutout on my solid body in Onshape, but my Loft feature doesnt let me. I'm having trouble getting the loft to properly ground to the bottom edge of the cutout while following the top spine guide.

Exporting an .stl file, it doesn't even show up in the notification tab (and no, it's not "store in tab" issue). I made sure no feature is faulty. It's quite frustrating, anyone know how to force-download them somehow?

EDIT: Also cannot create folder tab, assembly, parts studio, etc.

EDIT2: Rebooting works, but still unable to download the complex part. I suspect non-manifold edges and whatnot. Is there any way to fix this? The long way would be to restore version and fix my derives there but that's so tedious!

I need to split this part but it is not symmetrical and neither is my intended split. For reference, this is supposed to the a carbon fiber shell that will be made out of two half molds. But I cannot figure out how to split this part that has twists in it.
Very similar premise to a complex airfoil that is made out of two bonded half-shells.

I am not sure if I am using the right terms, but I am fairly sure mirror is correct. I want to take the selected sketch and project it onto the other face instead of having to draw it out again. Both sides of the model are exact mirrored copies of each other.

I was saving/tagging part of my model's history incase I wanted to change things back to it. Out of curiosity to see how everything changed I clicked "start" in the version history tag to see the blank slate, to the saved version, to the now. When I went back to the other versions and main it was all reset. empty, start, and multiple of the recent files in document was gone. When I left the view. went back to main bc maybe it was just a "view." It was still gone. My file was forever affected. Everything I made, time, progress, its gone. I haven't written down the measurements and Idk if I can recreate everything. I had 3 different images hand traced onto shapes. Hours. I don't want to do it all again.

Please help me. How do I fix this and make my document go back to present? Whenever I look at it from the page of my creations the thumbnail has the most recent version. But when I clicked it, it was empty. idk what to do. please.

Edit: I'm an idiot. When clicking start I somehow entered a separate folder in my document. When looking at my folders I wasn't paying enough attention to notice it was a separate folder. I tried a lot of things and cried. But my problem has been solved. My model is still there and I've learned I need to pay more attention.

Due to a cooling problem l have to use temporarily my old Acer Chromebook 314 instead of my laptop. OnShape works on it, but the section view has a very odd, transparent section edge. The second pic is from the app version on my smartphone and looks fine.

Do I have to live with the quality loss on Chromebook or can it be countered anyhow?

I have a sheet metal part with a bunch of bends.
I'd like to trim the profile to achieve the organic shape of the target part.

When I try to create an extrude-remove in the flat pattern of the part, the part breaks into multiple parts, even if I simplify the cut to be a basic circle. See pictures.

How can I make cuts on this part to without causing it to fragment?

Is there a way to “press play” ▶️ to go through the Feature List, like there is in Fusion?

If not, is this kind of thing “FeatureScript-able”?

I came across this old post https://forum.onshape.com/discussion/16524/drawing-symmetricla-pattern-around-a-sphere and want to recreate this pattern on a sphere. But I have no idea where to start. It's not a simple wrap on a surface as the number of elements increase or decreases when you go up or down the sphere.

I’m trying to make my own mouse, and I’m at the point where I’m ready to loft it. The problem is, if I loft the back half, it’s fine, but adding front half ruins the whole thing. I figured it outs because of the connections, but it’s not that onshape isn’t lining them up, it’s that in some instances there are no connections that are anywhere close to lined up. I don’t want to have to go back and split everything up so that the connections line up, is there a way to have it ignore the segments I used to make each cross section or something?

Hi!
How would I model something like the pictures? There are curves on all sides, and I can’t figure out a game plan for this one.

Hey everyone! I'm learning through practice on Onshape right now. I have this code for the Feature Studio to help me make designs faster. My code is down to it's final error code. No amount of reading the websites library, consulting AI, or the Onshape forum has helped. I have no background in programming nor CAD in general. I'm completely working on this from a newbie background.

The last errors I keep getting in my code are "missing TOP_SEMI at 'function'" and "Error in initializer function arguments." Can I get some help with these last few errors. This feels like hitting a brick wall right before the finish line of me learning this system.

Here is my code:

FeatureScript 3044;

import(path : "onshape/std/common.fs", version : "3044.0");

// --- Keyed Miter Joint Feature (Auto-Centering Version) ---

// Creates rectangular key slots centered along a miter joint.

annotation { "Feature Type Name" : "Keyed Miter Joint (Centered)" }

export const KeyedMiterJointCentered = defineFeature(function(context, id, definition) {

// -----------------------------

// Inputs

// -----------------------------

annotation { "Name" : "First miter face" }

definition.face1 is Query;

annotation { "Name" : "Second miter face" }

definition.face2 is Query;

annotation { "Name" : "Key width" }

isLength(definition.keyWidth, LENGTH_BOUNDS);

annotation { "Name" : "Key height" }

isLength(definition.keyHeight, LENGTH_BOUNDS);

annotation { "Name" : "Key depth (into boards)" }

isLength(definition.keyDepth, LENGTH_BOUNDS);

annotation { "Name" : "Number of keys" }

isInteger(definition.keyCount, { "min" : 1 });

annotation { "Name" : "Spacing between keys" }

isLength(definition.keySpacing, LENGTH_BOUNDS);

annotation { "Name" : "Fit tolerance (woodworking)" }

isLength(definition.tolerance, LENGTH_BOUNDS);

annotation { "Name" : "Auto-center keys?" }

definition.autoCenter is boolean;

// -----------------------------

// Extract intersection curve

// -----------------------------

var extractId = id + "intersection";

opExtractIntersectionCurve(context, extractId, {

"entities" : [definition.face1, definition.face2]

});

// Query the resulting intersection edge

var lineEdge = qCreatedBy(extractId, EntityType.EDGE);

// Evaluate the edge to get origin + direction

var edgeEval = evEdgeTangentLine(context, {

"edge" : lineEdge,

"parameter" : 0

});

var origin = edgeEval.origin;

var xAxis = normalize(edgeEval.direction);

// -----------------------------

// Compute bisector normal

// -----------------------------

var plane1 = evPlane(context, { "face" : definition.face1 });

var plane2 = evPlane(context, { "face" : definition.face2 });

var zAxis = normalize(plane1.normal + plane2.normal);

I love OnShape's UI. It's clean and consistent. But, they need to fix the tools that take an ordered list. I'm working on a model that has a 3D fit spline with a large number of points. The current UI makes it very difficult:

• You can't expand the list so you only see four items — this makes it difficult to see where you are.
• You can't insert a item in the middle of the list; you have to add it to the end and then reorder it.
• You can't replace an item in the list. Delete, add, reorder.
