RayCAD vs Bimrock Autotag: the Bimrock alternative for production MEP tagging

RayCAD tags your MEPF production drawings so your drafters review the sheet instead of building it. Bimrock Autotag automates MEP tagging in Revit too. We make RayCAD, and we ran Bimrock on production drawings in September 2026. Here's what we found.

A sheet you can issue

Bimrock sells "overlap-free tag placement". RayCAD avoids overlaps too, and then packs tags the way an experienced drafter would. Each tag sits close to the element it describes, goes inside the element when it fits, and gets a leader only when it needs one. Leaders join the tag square, never cross another tag, and only bend outward.

Every tag on the sheet is valid

An empty tag or a "?" on an issued sheet turns into an RFI. RayCAD checks every tag before it places it. If a tag would come out empty or as "?", RayCAD leaves it off and lists it in the review panel with the reason, so the layout is built from valid tags only.

About 15 times faster

RayCAD tags a section in under 5 seconds, often under one. The biggest floor plans take a minute or two, and 200 tags take about a second. Bimrock took 15 to 20 minutes per view on the same kind of drawing.

What Bimrock Autotag is

Autotag is a Revit plugin from Bimrock AI. It places tags from rule-based profiles that set a position priority, interval tagging, and filters by direction, size, system, type and length. Bimrock's home page now leads with "Automate MEP Design & Engineering", and the company also sells RapidDesign, an MEP modelling tool. Its FAQ says "Annotation is just the start."

What we saw on production drawings

In September 2026 we ran Bimrock Autotag on a live HVAC floor plan, the kind of sheet firms issue every week. This is what it produced.

Bimrock's own demos show the same fan on a much smaller view. The one captioned "a dense multi-trade view" is a 1:50 close-up with about 20 tags, with a column of pipe tags whose leaders all meet at one point. Every public demo we found is a sparse view with open space around each tag. Shop drawings don't look like that.

RayCAD is built on dense production sheets, where many elements need 5 or 6 tags. Here is a whole congested HVAC floor tagged by RayCAD, then a closer look at one part of it.

Questions to ask before you choose

What happens when the setup isn't perfect? Nobody configures a tagging tool perfectly on day one. A rough RayCAD config still gives you a usable sheet you can tidy up. The Bimrock run above is what a rough config looks like there.

Where does my data go? Bimrock's Autodesk listing says Autotag sends "stripped-down placement information" to a server on Google Cloud and keeps it for up to 60 days. Bimrock doesn't say what that information contains, so it could include geometry and parameters from your model, and you have no way to check. RayCAD places every tag on your machine. We send usage telemetry only (counts and timings), list it on our security page, and let you switch it off. We sign an NDA. Run Wireshark while RayCAD tags a view and check for yourself.

Will it follow our standard? RayCAD's config panel sets leader attach points, the tag layout inside ducts, orientation per tag, how often to tag, the minimum length to tag, and whether to tag before a change, after it or both. Generate Config reads your project and proposes the mappings. If your firm needs something the options don't cover, we change RayCAD for you.

Who do we call when something's wrong? With RayCAD, the founders. Every customer gets them directly on WhatsApp or Microsoft Teams. On Bimrock's $49 plan, onboarding is "self-serve via docs and videos" and support is a Discord community.

Will it crash Revit? Firms run RayCAD all day on real projects. Every crash a firm hit has been found and patched, so RayCAD almost never crashes now. Read more on stability.

Which trades? RayCAD tags HVAC and piping today, native and fabrication. Electrical and fire sprinklers ship next week. Every release is tested on live projects at several client firms before it goes out, so what ships works on real drawings.

Orbit Engineering Services reports around 70% less tagging time with RayCAD compared with its previous manual workflow. See faster turnaround.

Price, trial and onboarding

RayCAD costs $200 a month for the whole company. Every drafter gets a license and usage is unlimited, so nobody waits for a floating seat. Bimrock's $199 plan buys 5 licenses meant for "10-20 designers".

If you work alone, start on the free trial. If you need only one license after that, talk to us and we'll agree a price for one seat. You get the same RayCAD a 50-person firm gets: neat sheets, valid tags, seconds per view, your data on your machine, and the founders a message away.

Bimrock's $49 plan comes with "self-serve onboarding via docs and videos" and a Discord community, during the trial and after you pay. A trial you run alone mostly tests how well you read the docs. RayCAD's trial lasts 15 days with every feature and unlimited usage, and we spend it with you. We onboard your whole team, set RayCAD up to your standard and run it with you on your live sheets. If you didn't get to use it properly, we extend the trial. We talk price once you've seen what RayCAD saves you. See pricing.

Where RayCAD fits

Tagging is one of the biggest time sinks left in MEP drafting, and solving it takes a team that works on nothing else. Bimrock's home page now sells "Automate MEP Design & Engineering", and it has launched RapidDesign, an MEP modelling tool, while tagging is still unsolved. Firms that build their drafting habits around a tool pay for that drift. RayCAD does tagging only. We've shipped 23 releases in 15 weeks, each with fixes and improvements from customer feedback. Read the changelog.

Try RayCAD for 15 days on your own live sheets. We'll set it up with you, and you can decide once you've seen the savings.

We make RayCAD. The Bimrock facts come from Bimrock's website, its Autodesk App Store listing and its YouTube videos, checked on 9 November 2026 and listed in the sources. The screenshots and timings marked September 2026 come from our own runs of Autotag on production drawings, on the version current then.
