Overview

Nexus gets a drawing most of the way there: it picks views, places initial dimensions on the view that reveals them, adds notes, and helps apply tolerances and GD&T. You describe the intent and the standard; Nexus drafts to it, following ASME Y14.5, ISO 128/8015, or your own house rules.
Treat Nexus as a drafting assistant, not a replacement for a final check. It gets you to a strong first pass — views, dimensioning scheme, tolerances, notes — but a full production-grade, release-ready drawing still needs a pass from an engineer. Run Drawing Review and a human check before it goes out.
Always select the Drawing agent — then describe the goal, attach context, and send. Capabilities: Part & Assembly Drawings · Multi-view · Section & Detail · BOM & Balloons · GD&T

​
Doing the same drawing over and over? Train a workflow

If you generate the same style of drawing repeatedly — same template, same view scheme, same tolerancing rules, just a new part each time — this is the best way to do it. A Workflow turns that entire drawing procedure into a button: train it once on a real part, then create every drawing after that with a click instead of a prompt.
1

Build it on one part

Produce a drawing exactly the way you want it — your template, your views, your dimensioning scheme — in a workflow chat.
2

Test run to validate

Run it once for real on a representative part. Once it passes, Nexus saves it as a validated workflow.
3

Run it for every new part

For the next part, open the workflow, swap in the new file, and hit Run. Same template, same views, same rules — no re-prompting.
See Workflows for the full guide to building, validating, and running one.

​
Two ways to work

You can steer every step or hand Nexus the goal and let it run — either way produces the same drawing.

Step by step — fast & precise

You make the calls. Each step runs straight through and lands exactly what you asked for.

Hands-off — least effort

Describe the goal and Nexus picks the views, scheme, and layout for you.
What steering looks like — one prompt at a time:
Each step is small and you can check it before the next. Prefer hands-off? The same drawing from one prompt: “A3 third-angle, fully dimensioned, with a section through the bore.”

​
Three built-in workflows

Nexus ships with three predefined drawing workflows. Launch them from the buttons at the top of the chat. Treat them as starting points — open any workflow and edit the steps to match your standards: your template, your planning rules, your review checklist.
Decides how to draw the part first — manufacturing method, primary view, the view set, dimensioning scheme, sheet, scale, and GD&T. You approve or adjust, then it executes.Edit it to encode your planning standards.
Produces a standard drawing end to end, the way your shop always does it.Edit it to point at your template and house conventions.
A manufacturing and standards review — checks the drawing feature by feature against ASME/ISO and your house rules: missing or wrong-view dimensions, blank title-block fields, missing tolerances, overlaps.Edit it to match your review standards. See Drawing Review for the full workflow and example prompts.

Example prompts

​
You’re in control

​
1. Attach a template — anywhere

Drop your .drwdot into a workflow, attach it in the chat with the clip icon, or specify its path. Nexus uses it either way.

​
2. Select it, then say what to do

Select dimensions or views in your CAD modeler, tell Nexus you’ve selected them, and it edits, deletes, or updates just those.

​
3. Stop it when it deviates

If Nexus heads the wrong way, hit stop and redirect — you’re never locked into a run. Correct it in a sentence and carry on from where it was.

​
4. Teach it once, reuse it forever

Run a task — say, applying your tolerance standard. Once it’s right, tell Nexus to save those steps as a skill, then reuse it by name:
For a full drawing you regenerate for every new part — not just one sub-step — save it as a Workflow instead: same idea, but triggered with a Run button instead of a prompt. See Doing the same drawing over and over? above.

Tips for drawing creation prompts

  • Specify the standard upfront — ISO and ASME Y14.5 have different annotation conventions, projection methods, and tolerance interpretation rules. State which applies.
  • Be specific about views and layout — name the views, sheet size, projection angle, and scale. The more you name, the more precisely Nexus lands it.
  • Name datums explicitly — when applying GD&T, specify datum letters and which faces they correspond to so references are consistent across features.
  • Describe what’s already there — if a drawing exists and you’re adding to it, tell Nexus what views and dimensions are already present so it doesn’t duplicate them.
  • Run Drawing Review before sending it out — after generating, run Drawing Review to check for undimensioned features, blank title-block fields, and missing tolerances before sending for approval.
  • Plan for a final human check — Nexus gets views, dimensions, notes, and tolerances most of the way there in one pass, but treat the output as a strong draft. Have an engineer review it before it’s treated as production-grade and released.
  • Train a workflow for repeat jobs — if you generate the same drawing style from a template over and over, validate it as a Workflow once, then run it for every new part instead of re-prompting.
