Cut sections, place components, organize parts and prepare drawings in Bill-Builder. Keep your complete project, then take the exact files into CAD when you need them.
Open Design with library → Library. Import a STEP or STL component and choose Choose fit & preview. Position it on a picked scan surface, at a datum or relative to a parent part; inspect the preview before committing.
Surface normals and inward offsets assist placement. The layout screen does not certify running clearance, motion or structural strength.
Name layers, isolate a part and control visibility. Add the part number, material, revision and notes before producing drawings or handing the project back.
These project properties follow saved revisions and complete-project files. Imported STEP metadata does not recreate a native CAD feature tree.
In Surface & color → Automatic scan → NURBS, pick a small patch and set its size and tolerance. Fit the patch, inspect the deviation result and export the accepted STEP sheet.
This creates a local open surface. It does not automatically rebuild the full character into a smooth, watertight solid.
In Export → Prepare shop drawing, choose the selected geometry or visible assembly. Add the title and revision, then create front, top and side views with dimensions.
Save the scaled SVG/PDF and full-size millimetre DXF views. Check dimensions and engineering requirements before using a sheet for fabrication.
Select the region or saved cut. Choose Export selection → STEP → Generate review STEP. Wait for Ready, download the ZIP and extract its STEP.
The current C01 STEP service makes bounded faceted review solids. Changing the cut requires a new export. STL is mesh geometry; a DXF is a drawing or section profile.
Use Save complete project to retain the review geometry and design recipe in a .go3d.json file. Use Open complete project to continue that work. Save a named checkpoint before a major change.
Cloud history keeps design settings and revisions; a complete-project download also carries the review meshes. Keep original supplier CAD separately.
Open Project QA, describe one issue or improvement, add the relevant revision and choose its priority. Keep the receipt so you can update that item and see its recorded result.
For CAD feedback, include the exact file, part, units and operation. A useful report says what you tried and what happened.
