STL File Size

[Measure]

We're having issues loading STL files over 30mb. I have a sample file I can provide of a 38mb binary sphere.

Using the Model Viewer sample...

- Loading STL files is slow, regardless of file size.
- Turning off crease detection/normal calc does help speed things up.
- Files over ~30mb result in a crash.
- Manually read and push data to mesh increases limit to 50mb and much faster.

Any ideas on how to improve this? We have many files in the 50-100mb range.

Sorry about that.

In my experience this is most often caused by post processing of the loaded mesh. Try disabling everything using ISTLDataContext_DG. Search the samples for an example.

We will look at it asap. It has to be v 7.3 unfortunately. It should be out around November. We will see if we can post a beta version earlier.

Good news:
We have moved forward v7.3 and made improvements in the STL load. By default, it does not do any analysis or surface improvements now. I was able to load 150MB file in 7 seconds.

We did not do much testing there. We will keep testing to check for anything broken, but I think it should be OK.
