No preview available for stp-model


when I upload a STP-214 file, there is currently no model preview available. I tried it in Firerfox and Chrome, Win10. It works, though when I review the parts of former order.

What can I do?

Best regards,


It can happen if your model is too “heavy” for our software to process it on the fly, e.g. because of a large number of triangles. It could also be a temporary issue. Please try uploading your model once again.

Normally, we receive all the information even if preview is not available. However, you can send us your file at and we will check it, upload it, and then send you a link to it.
