I have three leaf designs currently saved as STL files, and I need them in editable STEP format today so my pattern printers can pick up the work immediately. While converting, I also need significant changes made: • Resizing each model to fit updated dimensions I will provide. • Adding a few simple features (small veins and a locator tab). • Combining specific elements from the three leaves into a single master file as well as keeping them as individual parts. Please keep surface quality crisp, maintain watertight geometry, and return fully parametric STEP files ready for further CAD edits. If you can turn this around within the day, let’s get started right away.
