Spotlight: HP SitePrint, and a browser editor for the layout file

HP added a cloud CAD editor to SitePrint at AU 2026. Field crews can tweak a print-ready file without sending it back to Revit or AutoCAD.

Yesterday’s unused story was a new terrestrial scanner. The leftover Autodesk University note that still matters on site is a file-handling change: HP put a cloud CAD editor inside SitePrint.

That is not a new robot. SitePrint already prints walls, points and text onto the slab from a 2D CAD file, locked to a robotic total station. The usual waste is the round trip before the first line goes down. Someone exports a DXF, someone else runs the HP plug-in, the file sits in the cloud, and a last-minute opening or a moved shaft sends the crew back to a Revit or AutoCAD seat they do not have on the floor. AEC Magazine says that preparation can now happen in a browser editor built into the SitePrint platform.

What actually changed

The editor is the useful sentence. Previously the print-ready file had to be built in a separate CAD application and uploaded. Now HP says teams can edit and prepare that file in the cloud, with dedicated tools and automations for pre-layout setup. Operators on site can correct the job themselves instead of waiting on the office. Large Format Review repeats the same claim and calls out smart setup tools in the browser.

Do not read that as “the BIM model now drives the robot.” SitePrint still wants a 2D CAD file. HP’s product page is unchanged on the first step: if you have a 3D model, convert it to DXF. The new editor shortens cleanup on that 2D sheet. It does not replace a coordinated model, a written layout scope or a check that the printed line sits on the grid.

The other AU change is navigation while the job is running. AEC Magazine describes Smart Navigation as depth cameras and sensors that see unmapped obstacles — material, plant, temporary works — and re-plan the path without an operator stepping in. Large Format Review adds intelligent recovery for debris, obstructions and small path deviations. HP already sold a Smart Navigation package on earlier SitePrint units. Treat the AU note as an extension of that autonomy, not a second robot.

Xavi Juarez, HP’s Large Format AEC product director, told Large Format Review the machine has been used on more than 3,900 projects in over 20 countries. That is scale, not a tolerance. HP lists layout accuracy up to plus or minus 2 millimetres on a high-accuracy setup with a specified prism, print mode and a 1-second total station, at 5 to 30 metres. The same page is blunt: the layout is as accurate as the control points.

HP also restated Build Workspace version control, drawing comparison and QR checks. Those drawing-management pieces were already on the table earlier in 2026. They are not the reason to write this week’s method.

What a BIM or VDC lead should do

Do not open the authoring model from the slab because a browser editor appeared. Keep the coordinated 2D layout as a issued file. If a superintendent moves a door in the cloud editor, that change still has to come back as a revision, not as tribal knowledge on the floor.

If the firm already loses a half-day every time a shaft moves after the DXF left the office, this is worth a trial on a non-sensitive floor. Export the same layout you already trust. Make one controlled edit in the browser — a held opening, a note, a line you would have sent back to CAD. Then ask four questions: did the printed geometry match the issued file except for that edit; did the change get recorded as a revision; did the robot finish around the clutter that is actually on the floor; and did the ink sit on the control you already use.

If the answers are yes, you can shorten the office loop. If a 50 millimetre hold disappears because someone “fixed” the file on a tablet, keep the authoring seat in charge.

Quick answers

Frequently asked questions

What did HP announce?

On 15 September 2026 at Autodesk University, HP introduced a cloud-based CAD editor built into SitePrint and accessed in a browser. The same briefing describes Smart Navigation that re-plans around unexpected floor obstacles, plus drawing-management updates in HP Build Workspace.

Does this replace AutoCAD or Revit for layout?

No. SitePrint still prints a 2D CAD file onto the slab. The new editor is for preparing and correcting that print-ready file. Authoring and coordination stay in the tools you already use.

How accurate is the printed layout?

HP lists layout accuracy up to plus or minus 2 millimetres under a high-accuracy setup with a specified prism, print mode and 1-second total station. HP also says the layout is as accurate as the control points. Treat the figure as a vendor number until you close it on your control.

Is Smart Navigation a new robot?

No. It is a navigation update on the existing SitePrint unit. HP and AEC Magazine describe depth cameras and sensors that detect unmapped obstacles and re-plan the path without an operator stepping in.
