I will create a parametric 3d cad model and export step and stl
Jiale Tang
About this gig
3D CAD modeling with a fast, clean turnaround.
Send me your sketch, a photo, or just a list of dimensions and I'll turn it into a clean, parametric CAD model plus the files your shop or printer actually needs.
WHAT YOU GET
- STEP and STL files (STEP opens in SolidWorks, Fusion, FreeCAD, NX, Inventor)
- DXF and DWG cut files on Standard and Premium (for laser, waterjet and plasma)
- Parametric models, so small size changes take minutes, not hours
- A preview render before delivery, so you approve what you get
TYPICAL PARTS I MODEL
Brackets, plates and flanges / enclosures and housings / adapters and spacers / fixtures and jigs / functional 3D-printable parts
HOW IT WORKS
1. Message me with the function of the part and its key dimensions, or attach a sketch or photo.
2. I confirm the scope and delivery time.
3. You receive STEP/STL (plus DXF/DWG and a PDF drawing on higher packages), plus a preview render.
PLEASE NOTE
- I deliver STEP and DXF files, not native SolidWorks files or 3D DWG.
- I do not do reverse engineering from scans or certified/stamped drawings.
- For something complex, message me first and I'll confirm the right package.
Delivery style preference
Please inform the freelancer of any preferences or concerns regarding the use of AI tools in the completion and/or delivery of your order.

I create clean, parametric CAD models and the files fabricators and 3D printers actually need.
- STEP and STL 3D models (open in SolidWorks, Fusion, FreeCAD)
- DXF and DWG cut files for laser, waterjet and plasma
- Sheet-metal flat patterns
- PDF engineering drawings
- Simple assemblies
Mechanical parts: brackets, plates, adapters, enclosures, printable parts. Parametric = fast revisions. No native SolidWorks files or certified drawings.
Send your sketch or key dimensions and I'll send a preview before delivery.

FAQ
What files will I receive?
You get the STEP and STL of the model. Standard and Premium also include a DXF cut file and a PDF technical drawing. STEP opens in SolidWorks, Fusion, FreeCAD, NX and Inventor. I don't provide native SolidWorks files.
What do you need from me to start?
The function of the part and its key dimensions. A hand sketch, a photo with a ruler, or a written list all work. If you already have a STEP or STL, send it and I'll work from that.
How many revisions do I get?
Basic includes 2 revisions, Standard 3 and Premium 5. A revision covers size and feature changes to the agreed design, not a completely different part.
Can you make a 3D-printable part?
Yes. I model it with printable wall thickness, no thin walls and a flat base, then deliver a print-ready STL. Tell me your printer and material so I keep the tolerances realistic.
