Real HLR line art — not a rendered screenshot

Generate technical drawings automatically

Upload a CAD model and get a complete engineering drawing back in about a minute: front, top and right views with proper hidden-line removal, an isometric, automatic dimensions, and a framed PDF sheet with a title block. No CAD seat, no drafting time, no manual view layout.

Drafted, not screenshotted

Views are computed by the OpenCascade HLR kernel on the exact B-rep geometry — visible edges solid, hidden edges dashed, every line a real edge of the part. It is vector line art you can measure, not a shaded 3D image.

Dimensions placed for you

Hole groups, radii, chamfer and taper angles, thicknesses and the overall width, height and depth are detected and dimensioned automatically — then you can drag, add or delete any of them before you export.

A full sheet, not just a picture

Every drawing comes as a framed PDF in A4 through A1 and Letter with a title block, plus vector SVG, 2D DXF and an STL mesh reference — the whole package in one download.

How it works

  1. 1Upload a STEP file — a single part or a whole assembly, which is split into parts automatically.
  2. 2Orient and name each part in the 3D preview so the front view is genuinely the front.
  3. 3Generate. The engine projects the views, removes hidden lines and places the dimensions.
  4. 4Adjust anything you want, then download the PDF sheet, SVG, DXF and cross sections.

Frequently asked

Do I need CAD software installed?

No. Everything runs in the browser — upload the model, get the drawing. You never open a CAD seat, and nothing is installed locally.

Which file formats can I upload?

3D: STEP (.step / .stp — AP203, AP214 and AP242) exported from any CAD system. 2D: DXF (.dxf), which skips the 3D stage and is dimensioned directly. DWG needs exporting as DXF from your CAD software first.

Can I change the dimensions it chooses?

Yes. Every automatic dimension can be dragged to a new position, deleted, or joined by ones you add yourself, and you can re-run the drawing with your changes applied.

Is it standards-compliant drafting?

The output is third-angle orthographic projection with conventional line weights, hidden-line dashing and a title block. It is built for quoting, shop-floor reference and documentation. Treat it as a strong starting point rather than a signed-off controlled drawing.

Is this an AI technical drawing generator?

It's better than that for engineering use: drawings are computed by a deterministic CAD kernel (OpenCascade), not a generative-AI image model. AI drawing generators produce pictures that look like blueprints; Drawlytic measures the real geometry, so every dimension on the drawing is exact and the DXF is usable in production.

Can I use it for manufacturing and production drawings?

Yes — that's the main use case. The package includes a dimensioned multiview drawing for quoting and shop-floor reference, a 1:1 CUT-layer DXF for laser cutting and CNC, and framed PDF sheets with a title block for documentation.

What does it cost?

Three drawings a month are free with no credit card. Pro is $19/mo for 100 drawings a month, with extra credit packs from $0.28 per drawing.
