Open STP on Phone

STP is a common extension for STEP CAD exchange files.

• STP files can describe complex precise CAD solids.
• Phone viewers rarely include full STEP kernels.
• Large assemblies can be hard to inspect without specialized CAD software.

OpenOnPhone is for quick local inspection. It does not replace the original professional app for editing, conversion, exact layout, formulas, measurements, security review, or full workflow features.
