Choosing CAD and CAM software
Pick based on the work you actually do. Sign making and relief carving suit a dedicated woodworking CAM package. Mechanical parts and assemblies suit parametric CAD with integrated CAM. Almost everyone ends up using a vector drawing program alongside whichever they choose.
Decide by the work, not by the feature list
| If most of your work is | Look at | Because |
|---|---|---|
| Signs, lettering, decorative work | A woodworking focused CAM package | V-carving, inlay and texture are first class features rather than afterthoughts |
| 3D relief carving | A package with real relief modelling | Reliefs are a specific kind of 3D that general CAD handles awkwardly |
| Mechanical parts, joinery, assemblies | Parametric CAD with integrated CAM | Dimensions, constraints and a change history are what that work needs |
| Simple flat cutting | The free tool that came with your machine | It genuinely does this, and there is no reason to buy anything yet |
| Artwork and logos | A vector drawing program, alongside your CAM | Drawing tools in CAM are rarely as good as a dedicated illustrator |
The categories
Woodworking CAM
Built around what CNC woodworkers actually do: V-carve, pocket, profile, inlay, texture, relief modelling. The strength is that the hard things in sign making are single features rather than workarounds. The weakness is that they are not parametric, so a dimensioned mechanical part is more work than it would be in CAD.
Parametric CAD with CAM
Sketch, constrain, model, then toolpath. Excellent for parts that must fit each other, for assemblies, and for anything where you will want to change a dimension later. Steeper learning curve, and relief carving is not its natural territory.
Machine-bundled software
Most machines ship with something, often free or low cost. It is usually enough for flat cutting and simple carving, and it is the right place to start. You will know when you have outgrown it, because you will be fighting it to do something specific.
Vector drawing programs
Not CAM at all, but most people end up with one. Logos, lettering layout, tracing and cleanup are all faster in a real drawing program, and the result imports as SVG or DXF. There are capable free options.
Questions worth asking before you buy
- What am I making in the next year, realistically?
- Does it do V-carving and inlay properly, if that is my work?
- Does it handle 3D reliefs, if that is my work?
- Is there a post processor for my controller?
- Is it a subscription or a one-time purchase, and how do upgrades work?
- Is there a trial version? Use it on a real project, not a tutorial.
- How good is the documentation and the community, which is where your questions actually get answered?
Software specific workflows in CHIP
Everything in CHIP's core areas is deliberately software neutral, because chipload and grain direction do not care what you drew in. Where a module covers a workflow specific to one package, it is labelled as such at the top so you know whether it applies to you.
