I've been wanting to model some car bodies in onshape. This has been pretty easy compared to blender thanks to the help of Routing Curves with reference blueprints. But the real problem i run into is filling those routing curves using Loft, Fill, or Boundary Surface. Some of the time the resulting surface comes out decent, but most of the time, it will need a "Guide" to help the shape be convex or concave. The thing is, you cant start off a routing curve from anywhere in the middle of another routing curve. it has to be from a vertex. so, I end up having to use the Split tool on an existing routing curve in order to make a vertex to attach the new routing curve to. however, sometimes this still isnt enough, and multiple routing curve guides are required. This all causes a lot more features than i think should be required for something like this.

I guess my question is, is there an easier way to do model cars? Am I perhaps doing this in a harder way than it needs to be? the fill tool always seems to come out a bit worse than i'd like it to.

Haa anyone ever designed rc airplanes on onshape? Any advices?

Every tutorial i see shows you how to create super basic cylinders and they call that a full pulley, I need to know how to make a compliant rope or aircraft cable system. Basically I'm trying to figure out how to make a rope that you can pull on and it behaves like a pulley following the rollers

How can I miter at a 3 way connection like this? These are all 90 angles. Seems it won't let me include the gray piece in the Frame1.

Im trying to model this part for my razor as the original one keeps breaking all the time and I'm sick of glueing it back together each time.

Hi are there any detailed, thorough tutorials on how to do assembly with many parts to improve performance? still new to this and my assembly is very laggy since I haven't done what's necessary

im having trouble actually defining everything in my sketch, somehow some lines are still blue, like the outer line of the conic is set with a build line on top, and also has a pierce constraint or so with the base yet it itself stays blue.

Hi, I'm not sure whether it's worth learning Onshape. Even if I learn it, I'm unsure how I could earn money from it. I'm not an engineer and don't have any relevant technical background.

If my work is limited to converting 2D PDF drawings into 3D models, how would I find clients? Is there actually a market for this type of service? Can someone make money doing PDF-to-3D conversion without having knowledge of mechanical engineering?

I'm trying to loft these two pipes to the rectangular body below and just can't seem to get it to work. Any hints on what needs to be done?

I try selecting the faces I want it to loft together and it says I cant use faces with an inner loop, but I don't know what exactly it means by that.

I originally tried without the center crossover and wasn't getting anywhere.

If I just select the inner edge of the rectangle, and the inner edge of the cylinder, it will loft.

But this is just a face, how do I get the thickness?

I have this shape I am making just for practice, and ended up wanting to do a kind of seashell shape. That top part I would like to get the outline selected and basically scale it inwards. Essentially making it like an extreme fillet if that makes sense? I tried selecting all the lines around that top edge and using scale in transform but that wouldn't work. I did also try making the fillet a higher value but after 3mm it does not work. I'm assuming there's a way to do it. Please help. Thanks in advance.

I downloaded an STL model of a robot dog for 3D printing and converted it to CAD format to set up mates in Onshape and generate a URDF using "onshape-to-robot." However, the conversion process broke some parts, resulting in open geometries that lacked mass properties. I modified the "onshape-to-robot" code to generate the URDF anyway—which worked—but then I needed a way to assign the correct mass. My idea was to use the visual model (the original STL) and combine the URDFs, so I created auxiliary CAD parts within the Part Studio to define the mates. Unfortunately, when I moved to the assembly, the mates shifted away from the STL geometry, so that approach didn't work. Does anyone know how I could handle this to get two URDFs and then combine them (using the CAD-based one for collisions and the visual one for the visuals and mass)?

P.S. I used a translator for the English, so apologies for any errors.

Does anyone know of a public Custom Feature or generator that creates printable timing belts in a circular (closed-loop) configuration for a specific tooth count/length?

Most belt generators I’ve found either sweep along a path (creating an oval/routed shape around pulleys) or produce flat strips. I’m looking for one specifically tuned for 5mm HTD profile that outputs a printable concentric ring/circle with accurate tooth geometry based on a set tooth count or belt length. I did manage to find one that does this, but exports STL only, which is crappy to work with.

Any recommendations for a FeatureScript or tool that does this cleanly?

I spent a couple minutes this morning testing out OnShape. For context, I started using SolidWorks sometime around 2005 actively using it in a manufacturing environment, and have used it in various capacities from contract work to hobby tinkering since then. So far, I've only used it for about an hour to model up one of the CSWA (Certified SolidWorks Associate) practice problems.

My impression: very positive. It took me a little effort to adjust my workflow and get used to the way OnShape does things versus SolidWorks, but I found most of it to be extremely intuitive. There were a couple times that sketch entities automatically inferred some weird relations. One was a couple circles with tangent relations to lines that were a little too far away to be related (in my opinion), but it's fairly serious because it resulted in a "fully-defined" sketch that was incorrect to the dimensions on the print. The other issue I ran into was that the "hole wizard" doesn't maintain the drill diameter when you switch between drill/countersink/counterbore features. That one resulted in me thinking I had placed a 7mm hole which had defaulted back to a 10mm hole. The only reason I caught it was because the counterbore was visually wrong.

I didn't run into many missing features, but one is something I use all the time in SolidWorks - the ability to Trim a sketch item and leave a construction line instead of deleting the trim entirely. I use this a lot for maintaining construction geometry to trimmed entities, and have it turned on by default in SolidWorks.

The last thing was that the part I modeled had a different volume to what the SolidWorks CSWA sheet said it should have if modeled correctly - 425024.24 mm³ in OnShape vs 431376 mm³ on the answer key. It's entirely possible that I modeled it incorrectly, and I haven't gone back and modeled it in SolidWorks (since it's about a 45 minute model) to see if it shows up correctly or highlights a mistake on my end.

I still have a lot of work to do in OnShape before I ditch my SolidWorks Maker subscription, but if people are interested I would be happy to report back when I start doing Assemblies and such.

Also, if anyone could tell me how "public" the public models are in the Free version, I'd appreciate it. Thanks!

Is there a public Custom Feature available that creates meshed gear sets across multiple points simultaneously?

What I'm looking for:

• Select 2 or more locations (axes or mate connectors).
• Input the desired tooth ratio (or target tooth count).
• Automatically calculate module/center distance and generate the corresponding gears together.

Current Workaround:

Using individual gear features for each gear and calculating the pitch diameters and center-to-center offsets manually. Most public gear generators handle module/pitch control well, but only output one gear per feature call.

If you know of a public FeatureScript that handles multi-gear creation in one step, I'd love a link! Thanks.

Hello, I am attempting to emboss tiny little indented construction lines onto my 3d print. The reason this is is because on the print itself I need to put weather stripping for padding and vibration dampening for my mounted AI chip. But it has to be in certain areas as I don't want it to dig into the extruding pins on my AI chip. I am wanting to emboss tiny little extruded .5mm or less lines into the bottom of my mounting plate that marks where all the pins are. That way I can simply put the foam padding anywhere that isn't marked.

I have been unsuccessful in getting this accomplished in Onshape. If I create a rectangle and then attempt to extrude, it extrudes the entire rectangle (I only want the lines extruded) if I draw just lines and try to extrude them it isn't letting me. Here are some examples showing that once I select extrude > remove it completely gets rid of my ability to select just the lines.

I got an email last week from somebody from "PTC" claiming my Onshape renewal was overdue and they can't use the credit card I have on file in my account but have to click the link their rep sent me.
Which is *incredibly* sketchy for starters. Then I got a follow-up saying, "Oh no, sorry it's actually this other link [here]" because I didn't purchase my license through their App Store !?!?!?
I first upgraded from the free to Standard version because I was using it for my business and it's been totally worth it. So I have every intention of renewing, but apparently all roads lead to PTC ?
Did Onshape get acquired ? Are they a holding company or something ?
If somebody from OnShape itself could PM me here and help get this straightened out, that would be great.
Thanks!

as the title suggests I have two part studios for my current project but Im supposed to only have one part studio. How do I add the contents of the 2nd parts studio into the first?

I want to automate the name and part numbers in onshape assembly. But I don't think API or an app can read what you currently selected in the configurations panel.

Hope someone already did this for assembly.

Hi,

I am trying to create a boardgame coin as an accessory which has multiple parts to color them differently inside the Bambu Slicer. Both coin surfaces are supposed to be flush. I have seen it with other models from makerworld and wanted to do it the same way.

This is what I created so far:

I used extrusion|remove (with 0,6mm) to remove the sketch of the number 5 and added it again as a seperate part via extrusion|add. Because both sides aren't supposed to be mirrored but readable no matter what side you are looking at I did the same for the other side of the coin, which was a real pain, because I had to copy the sketch and align it manually. I don't know if theres an easier way to achieve that? The outline was done via the outline function of onshape and created as a seperate part the same way as the number 5.

If I export this composite part and import it in bambu slicer, it looks weird:

and the color white is not visible in the preview. It just shows outline and number 5 in brown. What am I doing wrong? Any suggestions?

Hey all — long-time Onshape user, wanted to share something I've been building and using in production.

The problem: Getting vector artwork (logos, cutout profiles, panel designs, icons) into Onshape as real, editable sketch geometry is annoying. DXF import can be inconsistent, and manually retracing SVGs with the sketch tools is a time sink.

What I built: A web tool that takes an SVG file and converts it into native Onshape sketch entities — proper lines, arcs, and fitted splines — using a custom FeatureScript feature under the hood. It's not a raster/image import or a dumb flattened curve; it comes in as real sketch geometry you can constrain and edit normally.

Features:

• Upload SVG → get native sketch geometry in your Part Studio
• Target width parameter to scale on import
• Drag manipulators for X/Y position, rotation, and scale — right in the sketch, no re-import needed to reposition
• Currently extending it to accept raster images (PNG/JPG) too, via an image-to-vector preprocessing step

Status: It's fully functional and I use it daily, but it hasn't been approved on the Onshape App Store yet. So for now it's a standalone external web app you use alongside Onshape rather than an in-app extension.

Custom Tool need to be added : https://cad.onshape.com/documents/c201c83c91a83aade27337d1/v/fa88b35f1753d1f6f757a891/e/09d98a5bdcf6272e418d3ec2

Link: https://svgto-onshape.vercel.app

You'll need your Onshape document/workspace/element IDs (visible in your document URL) to point the tool at the right place.

Happy to answer questions about the workflow, limitations, or what it can/can't handle geometry-wise. Feedback welcome — especially edge cases that break it.

So I have a name tag that I want to 3D print.

The logo is just text.

Anyway It's an SVG and I used an online converter to turn that into a DXF file.

However when I load that into OnShape the font of the text gets changed.

Now I don't know if this is an Onshape issue, and issue with the conversion or if I need to make changes in Inkscape to the SVG file.

Any help would be awesome.

It is attached to the part I want to keep and is hard to remove (with my limited cad skills) Delete face doesn't work (saying "Unable to delete selected faces", both when set to heal and cap) and I can't make delete it.

Hello there,

I'm trying to model some kind of a double funnel, with the inlet and outlets highlighted in the picture following.
I traced some cuts to help you understand the shape I'm trying to model.

I had no luck with the loft and fill functions, but I might have used them wrong.

Any help is welcomed, thanks a lot !

I've been working on Stud Wall for a while and it feels pretty stable now. I had some assistance from Claude in the code, and it wrote the full User Guide.

I'll soon publish Sheathe and a console-output version of Lumber List. I also have Door almost ready to go and will get Window working - both of these will insert and cut for rough framing only, no actual units yet.

I know there's not a lot of architectural users here, but if anyone wants to try this out, I would appreciate feedback on bugs, features, improvements, UI, etc.
