Say the run the way you’d tell a drafter: direction, length, fitting. Type it or use your phone keyboard’s mic. The app draws the iso and numbers each field or shop weld. Built for API 570 inspectors and CWI weld mapping.
Create your ISO in the field, then finish your review in Bluebeam. Export a PDF and open it in Bluebeam Revu to add notes, revision clouds and stamps.

You walk the line. Count the joints, mark field or shop, note the lengths and take readings at each CML (condition monitoring location). Then the sketch sits in the truck until report day. The pipe hasn’t moved. The paperwork has.
Weld Map ISO Drafter AI draws the iso while the run is in front of you, and the weld map is on it from the first joint.
Type it or dictate it: direction, length, fitting. N 21'2", S 25'6", UP 6', W 78', BV. Split the pieces with commas. A bare number keeps going the same way and reads as feet — and the sheet says so.
The iso has dot paper and a north arrow. Each joint gets a weld number in route order. Tap FW/SW to switch between field and shop welds. If a turn has no fitting listed, the app adds a 90° elbow and marks it ASSUMED. Check it.
The route is a list of rows. Change a length, add a fitting or move a row. Add a CML where you took readings. Then tap Draw it.
Print letter-size or 11 × 17-inch sheets. Save the editable job file (JSON) as a separate backup. Every sheet says: FOR WELD &/OR CML MAPPING — NOT FOR CONSTRUCTION.
Every joint auto-numbered W1 to Wn in route order. Field weld solid, shop weld open — one tap flips it, on the list or on the drawing. The title strip counts them: FW, SW, total.
Tap a run or fitting to add a thickness point. Take 4 readings: 0° at the top, then 90°, 180° and 270°. The lowest reading prints beside the tag. Import the gauge’s spreadsheet file (CSV), or paste the readings.
Check the ASSUMED elbows and any “length?” flags. If you say only “valve,” the app puts it in STILL NEED so you can choose the type.
Long runs split across sheets. Match marks show where they join. A connector at the end opens the next iso and saves the current one first.
CMLs, welds, lengths, fitting names, supports, dot paper. Whatever you hide, the sheet says so: NOT SHOWN ON THIS SHEET.
Straight runs are proportional; fitting symbols are not to scale. Every sheet carries the line number, size and schedule, total footage, date, and FOR WELD &/OR CML MAPPING — NOT FOR CONSTRUCTION.

Built for API 570 piping inspectors and CWIs doing weld mapping on pipe — the field-weld/shop-weld map and the CML survey sketch that go in the report. If you sketch runs for a living and hate redrawing them, it's for you too.
$14.99 a month includes watermarked field sheets. Clean sheets use 0.5 credit each, from your account balance.
Need a weld log too?
No. It's a drafting hand, not an inspector. It doesn't accept anything, reject anything, or make one call on your behalf. You describe the run, it draws the iso with the weld map, and you review it the way you'd review anything out of a drafting department.
Check the route against the pipe while you’re still at the job. Fix wrong lengths, fittings or directions in the rows and draw it again. Check each item marked ASSUMED before you use the sheet.
Straight pipe runs are drawn in proportion to their entered lengths, using one common scale within each sheet. Each sheet fits its available space, and fittings remain readable symbols. It is not a calibrated construction drawing: use the written dimensions, not a ruler or Bluebeam measurement tool, for actual pipe lengths.
Yes. Export the ISO as a PDF, open it in Bluebeam Revu, and add your review notes, clouds and stamps. Existing weld tags and CML labels are part of the drawing; they are not separate editable Bluebeam markups. Changes made in Bluebeam do not update the job in this app.
Clean files from this website include PDF, picture (PNG) and editable CAD (DXF) formats. Each sheet uses 0.5 credit. Watermarked field sheets are included with active access. Keep a separate editable job backup (JSON). Clean files are not available from native apps.
No. Type the route, use your phone keyboard’s mic, or build it row by row. Check the rows before drawing. The rows control what gets drawn.
The ISO subscription covers the drawing tools, weld mapping and watermarked field sheets. If the log is all you need, Weldbook AI is still $9.99/mo on its own.
