[SEC 02]Services
Capabilities
Four services, one standard of output. CAD and drawings that go straight to quote, programme and machine without a round of clarification emails first.
[SVC 01]3D Modelling
3D Modelling
Parametric solids built the way a machinist or fabricator needs them, not geometry that only looks right on screen.
Models are fully constrained and dimensioned from functional datums, so a design change is a parameter edit rather than a rebuild. Sheet-metal parts carry the correct bend allowance and K-factor for your press brake, which means the flat pattern you cut is the flat pattern that folds to size.
Assemblies arrive properly mated, with interference checks run and a bill of materials that matches the drawing tree. If you machine straight from the model you get clean solids: no orphan surfaces, no sliver faces, no imported geometry left unstitched.
What you get
- Native CAD files plus STEP AP214 and IGES exports
- Watertight STL exports, checked before release, where additive work is involved
- Assembly structure, BOM and part numbering to your scheme
- Sheet-metal flat patterns in DXF with the K-factor stated on the drawing

[SVC 02]Technical Drawings
Technical Drawings
Drawings a shop can work from without ringing up to ask what a dimension means.
Every drawing is produced to BS 8888, with projection, line work and annotation to ISO 128. Functional features carry GD&T to ISO 1101 (position, flatness, perpendicularity) taken from datums that match how the part is actually fixtured and inspected. Everything else runs on general tolerances to ISO 2768-mK, stated in the title block, so nothing is over-toleranced and nothing is left ambiguous.
Surface finish callouts, thread specifications to ISO 261 and ISO 262, weld symbols to BS EN ISO 2553 and hole tables for CNC drilling are included wherever the part needs them. Drawings are checked against the model before release: dimension chains close, the datum scheme holds up, and the tolerances are achievable on the machines that will cut the part.
What you get
- PDF drawing packs, plus DXF or DWG where you need editable 2D
- GD&T to ISO 1101 applied to functional features only
- General tolerances to ISO 2768-mK, or -fH where you specify it
- Your title block and numbering scheme, or BS 8888 defaults

[SVC 03]Design for Manufacture
Design for Manufacture
A second pair of eyes before the part reaches the machine, from someone who thinks in cutter diameters rather than CAD features.
A DFM review walks the part through how it will actually be made: internal corner radii sized to standard cutter diameters, tool access and workholding considered, wall thicknesses checked against chatter and distortion, tolerances relaxed wherever function allows. The usual outcome is fewer setups, standard tooling, and a cheaper part that still does its job.
For fabrications and sheet metal the review covers bend sequence and brake reach, minimum flange lengths, hole-to-bend distances, and whether a weldment could be a folded part instead. Where fit is critical the tolerance stack is calculated and written down, with a note on where precision is buying you something and where it is only costing you money.
What you get
- Marked-up review listing specific, actionable changes
- Revised models and drawings once the changes are agreed
- Tolerance stack-up calculations wherever fit is critical
- Setup count and tooling implications noted against each change

[SVC 04]Reverse Engineering
Reverse Engineering
For when the part exists but the drawing does not: obsolete spares, legacy tooling, components whose supplier has gone.
Working from the physical part, your measurement data or 3D scans, the geometry is rebuilt as clean parametric CAD with design intent restored. Real dimensions and sensible tolerances, not a point cloud frozen into a dumb solid. Critical fits are taken from the mating parts wherever you can supply them, so the remanufactured component actually assembles.
The output is a manufacturing pack: a fully dimensioned drawing to BS 8888 and model files in whatever format your machine shop quotes from. Material and finish are documented from what inspection can establish, and flagged clearly wherever they need confirming by test rather than assumed.
What you get
- Parametric CAD rebuilt with design intent, not a surface wrap
- Fully dimensioned manufacturing drawing to BS 8888
- STEP AP214, IGES and DXF exports for quoting and programming
- Assumed materials, finishes and critical fits listed and flagged
