How can I import STEP files?

arkopaul_sarkar

ISO 10303 or STEP is industry standard vendor neutral communication protocol for transporting CAD information. How can I import STEP files in Onshape. STEP also provides different APs to cover different domains (e.g. AP 214, Core data for automotive mechanical design processes). Which APs does Onshape support? Is there a way to extend the data integration for different AP format?

When the .step file is imported it imports thousands of surfaces and curves slowing down Onshape immensely

@Object_Mage does your step file open ok in another system? We can’t account for bad quality files, but if it is ok elsewhere please share it with support. For these bad quality imports it’s best to link that doc into another one so you don’t have to contend with a huge part/surface list.

That depends on the original model.
Most of what I have imported has come in as a solid. The items that come in as surfaces are usually caused by a zero length geometry fault caused by the original model having strange fillets or what have you. Usually these are parts from a vendor where they gave more detail to the part than necessary. (example: the threads on a grease zerk in the side of a bearing housing)
