MightyCad

Conversations

Open an earlier conversation to continue it: the chat comes back, and MightyCad continues from its summary and any plan still waiting for approval.

Benchmark

Development build. A test starts a new chat in Quick build (whatever the top bar says) and sends the test's request: MightyCad asks nothing, decides, calculates, builds, and writes the time and the AI cost under the result. Use a fresh SOLIDWORKS session and an empty project folder, and do not touch SOLIDWORKS until it has ended.

Cursor only - mouse and keyboard, no API tools (slow; to watch the cursor at work)

Company conventions

MightyCad learns how your company makes drawings from released drawings (PDF) - 10 for a first report, then add more at any time (up to 100 per batch; only new drawings are read). Each drawing is scored against ~200 parameters (title block, numbering, revisions, tolerancing per process, notes, GD&T...) plus the conventions it finds beyond them; values that keep appearing score higher, newer drawings weigh more. Drawing kind and processes are read from each drawing (e.g. die cast, then machined). Also add your template (.drwdot), sheet format (.slddrt) and note blocks (.txt) - they become MightyCad's defaults. Everything is kept in one file that survives updates; Export it to move it to another PC.

Settings

Anthropic API key OpenAI API key Gemini API key

Keys stay encrypted for your Windows account. Blank fields keep existing keys. Environment keys work in manual mode; automatic routing uses saved keys only. Use a paid Gemini project for confidential company work and review your provider's data terms.

Model combination

Suggestions are starting points, pending MightyCad drawing benchmarks. Selecting a combination changes roles below; Save applies it to new chats. When a provider hits a limit (quota, spend cap, rate limit), work continues on the cheapest default model of another provider with a key.

How work is split

Design defaults

The values MightyCad uses when a request gives none - wall thickness, clearances, fillets, holes, snap fits, tolerances per material and process. They go into every plan, so MightyCad does not ask about them; Quick build relies on them.

When SOLIDWORKS starts, continue the last conversation (instead of a new one) Draw a target vision before planning design jobs - an image model pictures the finished design from screenshots of your parts; plan, build and review work towards it (needs an OpenAI or Gemini key)

Inspects and plans, runs the work, then reviews the result. Failed checks promote the repair effort. Missing engineering requirements stop for your answers. Uses providers with configured keys; model access is checked by the API.

Routine tier override Standard tier override Advanced tier override

Repair attempts API calls per request

Estimated spending stop (USD) Checked between calls; the last call can exceed this estimate. Plan approval starts a new request budget. Provider billing may differ.

Fixed-role workflow (manual routing)

Company conventions

Plan approval (human in the loop) Design work, open questions and assumed values stop for your review: edit parameters, answer questions, or ask for changes before anything is built.

Lead model (plans) Effort

Executor model (implements) Effort

Reviewer model Effort

Scout model (cheap lookups for the lead) Lead inspects

The lead model only thinks: SOLIDWORKS basics are read automatically (no AI), other facts - geometry, dimensions, interference, mass - come from the scout.

Side questions model ("by the way") Effort

Pick a provider, then a model - or "Other…" to type any model ID that provider offers. Gemini maps xhigh/max to high; Pro maps medium to high. Unknown prices show as unavailable.

Models

Add any model your provider offers, or edit a name/price (edits override the built-in entry; Reset restores it). Prices drive the cost meter. Save to apply.

The spending stop of a request still applies. Stop it any time with the Stop button. Run scripts without asking (auto-approve) Let MightyCad use the mouse and keyboard in SOLIDWORKS (preview) Fallback for steps the API cannot do (PropertyManager options, dialogs). SOLIDWORKS windows only, only while SOLIDWORKS is in front, pauses while you use the mouse, 40 actions per 10 minutes.

Changes apply to new chats.

MightyCad chooses the AI models, the effort and the way work is split by itself, per request.
