# SOLIDWORKS automation without writing macros

> Macros and API scripts automate a fixed sequence and break when the model changes. CADABRA resolves intent against the actual file at run time, so one instruction covers the cases you would otherwise script.

# Automation that survives the next revision.

A macro encodes one sequence and breaks when the tree changes. CADABRA reads the model and resolves what you asked for against what is actually there.

## Why the macro library stops growing.

The reason is structural: a macro addresses features by name and position, so it works until somebody renames a feature, reorders the tree, or models the next part slightly differently. When it breaks, someone has to open the code.

The cost is not writing the first macro. It is that **every variation needs another one**, and each one has to be maintained.

## Macro, API script, or copilot.

|  | Recorded macro | API script | CADABRA |
| --- | --- | --- | --- |
| Who writes it | Any engineer, once | A developer | Nobody, you describe the outcome |
| Handles a renamed feature | No | Only if coded for it | Yes, it resolves against the model |
| Handles a part it has not seen | No | Rarely | Yes |
| New variation costs | A new macro | A code change | A different sentence |
| Maintenance | Silent breakage | Ongoing developer time | None to maintain |
| Best used for | A fixed, repeated click sequence | Deep, stable integrations | Everything that varies |

## The work worth automating first.

Where customers start.

### Batch drawings

One sheet per part across a whole assembly, on your title block. See [CAD to drawing](https://cadabrai.com/cad-to-drawing/).

### Family-wide edits

The same change applied across every part or configuration in a family, without writing a loop.

### BOMs from the assembly

Built from the assembly structure and ballooned to match the sheet, rather than retyped. See [BOM generation](https://cadabrai.com/bom-generator/).

### Component lookup

Fasteners sized to the hole and inserted from Toolbox instead of modelled by hand.

### Legacy conversion

Old prints rebuilt as live models, in bulk. See [drawing to CAD](https://cadabrai.com/drawing-to-cad/).

### Error triage

Rebuild failures and mate problems diagnosed in context.

## Keep the macros that work.

A macro that runs a fixed sequence on a stable template stays efficient. The API is the right tool for a deep, permanent integration with a PDM system.

What CADABRA replaces is the automation you never wrote: the long tail of variations where scripting was never worth the maintenance.

## Automation, answered.

### Why not just write a macro or an API script?

Macros work for a fixed, repeated sequence: they break when the feature tree changes, they need a developer to maintain, and each new variation is a new script. CADABRA resolves intent against the actual model at run time, so one prompt covers cases that would otherwise need a separate macro each.

### Can it generate drawings for every part in an assembly at once?

Yes. Batch generation runs the whole assembly in a single pass, producing one sheet per unique component plus the assembly drawing, each on your title block with the scale chosen from the geometry.

### Can it find the right component instead of me modelling one?

For fasteners, yes: CADABRA inserts them from SOLIDWORKS Toolbox, so you get the standard part your seat is already configured with rather than a modelled lookalike. It can also insert and mirror components you point it at. For anything else, Ask Mode can search the web for supplier and specification data, but nothing places a catalog part into your assembly for you.

### Does CADABRA integrate with PLM or PDM?

Not today. There is no PLM or PDM connector. CADABRA works on the files you have open and the drawing standards you upload, and your PDM rules around those files keep applying. If a connector matters to your team, tell us which system.

### How accurate is it, and who checks the work?

You do. CADABRA performs real operations on your model and shows exactly what it changed, so every edit is reviewable in the feature tree and revertible.

### How much time does it actually save?

It depends entirely on the work. The gains concentrate where the task is repetitive and well specified: generating drawings across an assembly, applying the same edit to a family of parts, and batch hole or fillet changes. On one-off modelling that needs judgement, expect little. The free plan exists so you can measure it on your own parts before paying.
