01
3D part modeling
Accurate solid models created from sketches, measurements, existing drawings, or reference parts—with manufacturing intent kept in view.
Parts · Configurations · Native CAD · STEP
02
Assembly modeling
Multi-part assemblies organized to check fit, motion, access, and the relationships that matter before work reaches production.
Assemblies · Exploded views · BOM-ready structure
03
Production drawings
Clear drawings with the views, dimensions, notes, and details needed to communicate the part without unnecessary clutter.
Part drawings · Assembly drawings · PDF · DWG/DXF
04
Legacy drawing conversion
Old prints, scans, and 2D files rebuilt as clean, editable CAD so future revisions stop depending on marked-up paper.
Redrawn prints · Editable models · Updated title blocks
05
Revisions and cleanup
Fast updates to existing models and drawings when dimensions, materials, features, or production details change.
Revision-controlled files · Clean geometry · Updated PDFs
06
Overflow CAD support
Flexible project support when your CAD-capable employee is needed on the floor, quoting work, or handling higher-priority problems.
One-off projects · Recurring support · Direct communication
Customer sketches need to become usable files.
The one CAD-capable employee is tied up in production.
Old drawings need revisions nobody has time to make.
A short-term workload does not justify another hire.
Where Haldan fits
When CAD work is slowing down real work.
Finish with what you need
Deliverables stay organized.
Final files are provided in the agreed formats with clear naming and revision status. Native CAD, STEP, PDF, DWG, and DXF can be included when appropriate.
Start with what you have
Inputs can be rough.
Clear information matters more than perfect presentation. Projects can begin with a sketch, marked-up drawing, reference file, measurements, photos, or a short call.
