Mechanical CAD modeling services
For machine shops, manufacturers and design studios that have defined requirements and need checkable 3D geometry. We confirm part count, assembly relationships and file formats before modeling. We also support peer studios with drafting and modeling overflow.
What to send for a quote
- Current drawings, dimensioned sketches or reference models, with the applicable revision identified.
- Confirmed dimensions, units, interfaces and features to retain. Photos help explain shape but do not replace missing dimensions.
- Part count, intended use, receiving software or required format, and your target delivery date.
What you receive
- 3D part models or small assemblies within the agreed scope.
- STEP / IGES or other agreed model files. Native files and software versions are confirmed when quoting.
- Key view notes where needed. Manufacturing drawings, complete annotations, sheet-metal flat patterns and new design work require a separately agreed scope.
How we review the work
- Review main dimensions, part count and model revision against the confirmed input.
- Check the agreed assembly relationships and interface representation; raise ambiguous dimensions for confirmation.
- Deliver the agreed formats and track feedback against the approved inputs and revision allowance.
Scope and production requirements
This service starts from existing design requirements. Concept development, engineering calculations, simulation, physical measurement and machining/fabrication are not automatically included. Manufacturing dimensions cannot be inferred from appearance alone, and a checkable model is not a substitute for design optimization or process validation.
UAV landing platform — 3D modeling
- Client provided
- Assembly references and modeling scope for a UAV landing / docking platform.
- CadBear delivered
- Built the landing platform and related mechanisms as a checkable 3D assembly, with model views that make assembly and mechanism relationships easy to review.
- Deliverables
- 3D assembly model, Key view notes
Questions before starting
Can you build a model from photos alone?
Photos can explain a shape, but critical dimensions, units and interface requirements still need confirmation. Send the available material first so we can identify gaps and assess the scope.
Can you revise an existing model and export STEP?
We check the source file, target software and requested changes first. Files retain different levels of editable information, so an extension alone does not establish which revisions are possible.
How is this different from design-plus-manufacturing or 3D scanning?
This service delivers models and drawings only — it does not include machining or fabrication, and it does not include structural concept decisions or material selection. 3D scanning and on-site measurement are outside the agreed scope for this item. For flat patterns or manufacturing drawings, see Related services below.
Quotes and lead times depend on source completeness, part count, complexity and agreed revisions. Send the available package first; we clarify gaps before confirming a schedule.
