AI CAD Generator

From a sketch, a photo or a few words to a clean technical flat.

Describe the garment or attach a sketch, a photo or a mockup. The CAD Generator draws it as a technical flat, front and back on one sheet, ready to download as a PNG or an Illustrator .ai file and to take into the mockup and the tech pack.

How it works

From idea to flat in three steps.

  1. 01

    Describe it or attach it

    Write the garment in the bar, or attach a sketch, a photo or a mockup to draw it from. A few words are enough to start.

  2. 02

    Ask for what you need

    Say it in the prompt: the front and the back, a detail, a different fit. Pick Studio white, or no background for a transparent PNG.

  3. 03

    Download it or keep going

    The flat comes back front and back on one sheet. Download it as a PNG or as an .ai for Illustrator (beta), or take it into the mockup and the tech pack.

Real flats

From the FUPstudio CAD library.

Next to the generator, FUPstudio keeps a library of ready-made flats. These are real files from it: 1,140 professional vector drawings, each with its .ai for Illustrator. Open one to see it there; the free ones download without an account.

What you can do

One flat, every next step.

Line up a collection

Draw every piece as a flat, front and back, and look at the whole lineup side by side before you sample anything.

Keep working in Illustrator

Download the .ai (beta) and finish the drawing in Illustrator, or use the PNG in a deck, a line sheet or a brief.

Change it in words

Ask for a longer sleeve, another collar or a different fit, and everything you do not name stays as it is.

Turn the flat into a mockup

Take the drawing into the Mockup Generator and see it as a photoreal garment, in the fabric and colour you choose.

See the Mockup Generator

Build the tech pack

From the mockup, the Tech Pack Generator writes the document a factory quotes from, with the technical flat on its own page.

See the Tech Pack Generator

Add a print

Make the artwork in the Graphic Generator, then attach it when you turn the flat into a mockup.

FAQ

Questions about the CAD Generator.

What is an AI CAD generator for fashion?

A tool that draws the technical flat of a garment: the black-line drawing, front and back, that pattern makers and factories read. In FUPstudio you describe the garment or attach a sketch, a photo or a mockup, and it comes back as a clean flat on one sheet.

What can I start from?

A few words in the bar, a hand sketch, a photo of a garment or a mockup. Ask in the prompt for what you need: the front and the back, a detail, a different fit.

Can I download the CAD as a vector file?

Yes, in beta. Every new CAD can be downloaded as an .ai file for Adobe Illustrator, traced from the drawing, or as a PNG. With no background, the PNG is transparent.

How much does a CAD cost?

A CAD at the default quality, High, costs 30 credits; Fast costs 10. Every account gets 250 free credits every month, no card needed.

Can I change a flat after it is drawn?

Yes. Write the change in the bar, a longer sleeve or another collar, and the rest of the drawing stays as it is. Every generation is saved in My Area.

What is the CAD library?

Next to the generator there is the Vector CAD library: 1,140 ready-made professional vector files, from garments to trims and fabric patterns, each with its .ai. The free ones download without an account; the full library comes with the Designer plan.

What do I do with the flat next?

Take it into the Mockup Generator to see the garment photoreal, in the fabric and colour you choose. From the mockup, the Tech Pack Generator builds the document a factory quotes from.
