CAD image colorization

CAD output is made for engineers. Handed to a customer, a procurement team or a sales prospect, a monochrome line drawing communicates far less than the same geometry with materials, depth and a highlighted assembly.

What this service covers

We take CAD exports and turn them into presentation-quality coloured illustrations, keeping the geometry exactly as drawn while adding material differentiation, shading and emphasis.

This is not a full 3D render. It is illustration built on your existing drawings, which is faster, cheaper, and keeps drawings that engineering has already approved.

Four stages, each with an approval point

01

File preparation

CAD exports cleaned and organised into a usable illustration base.

02

Colour convention

A material and colour scheme agreed and documented before production.

03

Colourisation

Drawings coloured, shaded and highlighted to that scheme.

04

Delivery

Layered files plus flattened print and screen versions.

The deliverables, item by item

01

Material differentiation

Metals, plastics, glass and composites distinguished by colour and finish treatment.

02

Shading and depth

Tonal work that makes an assembly legible without obscuring the line work.

03

Component highlighting

Selected parts emphasised for service, sales or training documentation.

04

Exploded colour views

Coloured exploded assemblies showing how components relate.

05

Background and context

Environments or scale references added where they aid understanding.

06

Layered output

Colour kept on separate layers so the underlying drawing stays intact.

What you get out of it

Reuses approved geometry

The engineering drawing stays authoritative; only presentation changes.

Faster than 3D rendering

No model rebuilding, no render farm, no scene setup.

Consistent material language

One colour scheme across an entire documentation set.

Editable afterwards

Layers mean a component can be recoloured without redoing the drawing.

Before you brief us

DWG, DXF, STEP, IGES and PDF exports all work. If you can produce a clean vector export, we can build on it.

No. Rendering builds a lit 3D scene from a model. This is illustration applied to your existing drawings — quicker, cheaper, and it keeps drawings engineering has already signed off.

Yes. A colour convention is agreed once and applied across every drawing so the set stays consistent.

No. Line work stays exactly as supplied unless you ask us to correct something, in which case we flag it first.
