Image-to-model

Sometimes the fastest input is a picture. This walkthrough turns a photo or hand sketch into an editable parametric model.

Before you start

  • A clear reference image
  • One or two known dimensions of the object
  1. 1

    Capture a clean reference

    Use a straight-on view with good contrast. A square-on photo or a tidy sketch reads far better than an angled, cluttered one.

  2. 2

    Upload and opt in

    Drop the image into the chat panel. Image-to-model is opt-in per image, so confirm you want this picture turned into geometry.

  3. 3

    Anchor the scale

    In the same message, give a known dimension — the outer diameter is 40 mm. This anchors the size so the rebuilt solid comes out to scale.

    Tip: One real measurement is the difference between a correctly sized part and a good-looking guess.

  4. 4

    Review the rebuild

    HelioCad interprets the image and builds a parametric solid. Check it against the reference and note anything to correct.

  5. 5

    Refine by chat

    Dial in the result with follow-up prompts just like any other model — adjust dimensions, add features, and clean up details.

What you built

A parametric solid rebuilt from an image and refined to match the real object.
