trouble with api not exporting GLTF model

ben_kepner

I am trying to make a tool for displaying and configuring a model on a web page. I got it working with exporting STL models, but the good javascript libraries for viewing models want GLTF. When I try to use the api endpoint for exporting it a GLTF, it appears to just return not enough data. The response code is '200 OK'

I am getting the same result from glassworks.

cloudflare threw a fit when I tried to past the results of the glassworks request into the post, so I made a pastebin. https://pastebin.com/xQWwxDeJ

Hi Ben, Can you include the units in the configuration string i.e. 

box_depth%3D2+cm

for example, this works for me

https://cad.onshape.com/api/v6/partstudios/d/6844173a888ae9c148ad6b67/v/57d8fe202591e452ce7fdae4/e/332466e1b8aefa108b60a691/gltf?configuration=add_dividing_walls%3Dfalse%3Badd_living_hinge%3Dtrue%3Badd_tape_slot%3Dfalse%3Badd_window%3Dtrue%3Bbox_depth%3D2+cm%3Bbox_height%3D7+cm%3Bbox_width%3D8+cm%3Bdivider_count%3D1&outputSeparateFaceNodes=False&outputFaceAppearances=False

I suspect the configurations without the units is resulting in invalid geometry and hence you are getting no output.

I was able to download the content using glassworks. As a test can you try downloading this with glassworks ? https://cad.onshape.com/glassworks/explorer#/PartStudio/exportPartStudioGltf . If that works, you may need to check the calls being made via the app.

adding units to the request worked. I wonder why it worked without for the stl endpoint?
