Turn Window and Door Sketches into CAD Drawings

LaunchAI converts window and door sketches and field measures into CAD drawings. Create opening layouts and approval elevations for custom doors and windows. The drawing is built from the supplied measurements, notes and specifications. Unclear details are flagged for your team to review.

Monday after the home show. Thirty-one contracts, thirty-one measure sheets.

Every one came back on the measure tech's clipboard, photographed at a kitchen table. Opening by opening: "BR2 DH 35¾ 36 35⅞ x 59⅞", a full-frame box checked on two of them, an "XO" on the slider with an arrow pointing at something. A homeowner email switching the front to prairie grids. A builder's rough-opening list for a spec house. And a custom door request: a phone photo of an arched entry with "RO 48 x 96, 2 sidelites 12"?" written on the drywall.

So you open the supplier's configurator and build it, opening by opening. Series, type, size off the smallest of three minus your deduction, or the RO minus a half inch. Operation and handing, from the outside. Glass package, tempered where the code says, obscure where the homeowner says. Grid pattern and type, colors inside and out, jamb depth, fin or insert, screen. Then the mulls. Then check the united inches against what the rep sold, and send the PO.

Custom windows don't go back on the shelf. A wrong size is a remake, another lead time, a second install trip and a homeowner with a board in the bathroom window. The rep's commission waits, and so does the next job on the crew's calendar.

What the job looks like today

  1. Read the sheet

    Which number is RO, which is frame, and which side the tech stood on.

  2. Do the deductions

    Smallest of three, minus your number, opening by opening.

  3. Build every line

    Type, size, handing, glass, grids, color, jamb: in the configurator.

  4. Check it against the contract

    Count, united inches, mulls, the change email from Saturday.

  5. Chase the gaps

    Text the tech about the slider. He's on a ladder. Wait.

Where it goes wrong

Every remake was a number that looked fine on the sheet

Measure techs are good. The trouble is in what the number was measured to, and which side of the glass they were standing on.

  • RO, frame or unit?

    On the full-frame job the tech measured the rough opening. On the insert next to it he measured inside the old jambs. Both say 36 x 60, and only one of them is the window you order.

  • Smallest of three

    Three widths, three heights, and the order goes in off the smallest minus your deduction. Type the middle one because it's the neatest and the window doesn't go in the opening.

  • XO from which side?

    Sliders and patio doors are handed from the outside. The tech stood in the living room. Now the operating panel is behind the couch.

  • The glass the code wanted

    A window over a tub with the sill low enough needs tempered glass. The sheet says "bath." The inspector says remake.

Why it's still manual

Software hasn't fixed this. Here's why.

Window and door suppliers have built good configurators. They are only as good as the person reading the measure sheet into them.

  • Your CAD and quoting software

    Waits for someone to type

    Paradigm, Soft Tech, A+W and Windowmaker configurators price and validate a unit once it's entered. For custom doors, AutoCAD draws the elevation once someone decides the sizes. None of them reads a clipboard photo.

  • Generic AI and OCR models

    Confidently wrong

    A chat model reads "35⅞" as 357/8, "6/8" as three-quarters, and hands back an XO slider without asking which side the tech was standing on. It won't notice the tub, and it won't tell you which sizes it guessed.

  • Image-to-CAD converters

    Traces lines, not intent

    Image-to-CAD converters trace the rectangles on the sheet. You get boxes in a DXF with no deductions, no handing, no glass and no idea which one was the bathroom.

  • Measuring apps and configurators

    Only if everyone uses them

    Laser measures and measuring apps help the techs who use them. The sheet still comes in as a photo of handwriting, and the custom door still comes in as a sketch on drywall.

How the agent does it

From sketches to CAD drawings and layouts

LaunchAI converts the sketch and its measurements into CAD geometry, applies your drawing standards and prepares the related order information. Missing dimensions and unclear notes are flagged for your team to review.

  1. Reads what came in

    Measure sheets, RO lists, emails and voicemails, with a confidence score on every value.

  2. Applies your rules

    Your deductions, tempered and egress rules, default glass, jamb and screen.

  3. Builds the order

    Opens your supplier's configurator and enters each opening the way your best order desk would.

  4. Asks only what it must

    Three widths that don't make sense? It drafts the text to the tech instead of guessing.

  5. You approve

    Confirm the flagged glass; the PO goes to the supplier.

FAQ

Windows & doors: questions we hear

We order from three suppliers, each with its own portal. Does it work in all of them?

Yes. LaunchAI agents use each supplier's configurator or dealer portal through the screen with your logins, the same way your order desk does. There's no integration to request from the manufacturer.

Does it replace our measure techs or the re-measure?

No. Your techs still measure. The agent reads what they wrote, checks it against your rules, and turns it into the order, so the office stops being where the mistakes happen.

What if a measurement is missing or the three widths don't make sense?

The agent never invents a size. It flags the opening, drafts a short text to the tech with the photo attached, and holds that line while the rest of the order is built.

Who approves the order before it goes to the supplier?

Your people. The agent builds the order and stops. Every flagged value has to be confirmed by someone on your team, and no PO is sent without that approval.

Can it handle custom and radius-top entry doors?

Yes. A sketch with the rough opening, sidelites and transom becomes an elevation in AutoCAD for the homeowner or contractor to approve, then the order or the shop's cut list.

How does it know our deductions and glass rules?

You give it your rules once: deductions by install type, tempered and egress rules, default glass, jamb and screen. They live in a rules table you can change, and every line shows which rule it used.
