Alternative to M4 PLANT.
M4 PLANT from CAD Schroer is a mature Windows CAD suite for 2D and 3D plant design. If you only need a standards-compliant P&ID with BOM — in the browser, no Windows requirement — piblaster is the direct route.
What M4 PLANT is built for
M4 PLANT is a factory and plant design suite with a 2D drafting system (M4 DRAFTING), a 3D plant model and steel construction. System requirements match that: Windows 10 or 11 Pro (64-bit), DirectX 10 capable 3D graphics card, three-button mouse, installation with admin rights. It fits engineering offices that actually do 3D design, derive piping isometrics, and work inside a classic CAD environment.
What piblaster is built for
piblaster is scoped to one job: producing standards-compliant P&IDs per DIN EN ISO 10628, maintaining them in a team, deriving the BOM automatically. No 3D, no CAD core, no installer — a browser tool that runs the same on Mac, Windows, Linux and iPad and is productive in minutes.
Head-to-head
| Criterion | piblaster | M4 PLANT |
|---|---|---|
| Platform | Browser (Win, macOS, Linux, iPad) | Windows 10/11 Pro 64-bit |
| Install | Not required | Setup with admin rights |
| Graphics requirement | Current browser | DirectX 10.1+ GPU |
| Focus | 2D P&ID plus BOM | 2D/3D plant and factory design |
| Symbol standard | DIN EN ISO 10628 | DIN EN ISO 10628 (and others) |
| Bill of materials | Automatic, Excel export | Via M4 PLANT modules |
| Team collaboration | Web-native, roles built in | File / license server based |
| Trial | 30 days, in the browser | 14 days (M4 P&ID FX) |
When M4 PLANT is the better pick
- You need 3D piping, steel construction or factory layout — not just P&ID.
- You already have a Windows CAD stack (AutoCAD, MicroStation) and want to stay in it.
- Isometrics, DWG interoperability and classic plotting workflows are mandatory.
When piblaster is the better pick
- The team fully or partially runs on Mac, Linux or iPad.
- New projects or working students need to be productive without an IT ticket.
- You need the P&ID and the BOM — not the 3D suite.
- External reviewers (customers, auditors) need to look in without installing software.
Frequently asked
What's the core limitation of M4 PLANT?
According to its datasheet, M4 PLANT only runs on Windows 10/11 Pro 64-bit with a DirectX-10 capable graphics card and needs a classic install. For macOS, Linux or iPad users, only a Windows VM bridges that gap.
Is piblaster a functional replacement for M4 PLANT?
No, and that's not the goal. piblaster fully replaces the 2D P&ID share — BOM and team workflow included. For 3D plant design, steel construction or factory layout, M4 PLANT (or a comparable CAD suite) remains the right tool.
Can piblaster export DWG or DXF?
piblaster supports export in common exchange formats. For specific DWG/DXF needs talk to us directly — we help evaluate whether the intended workflow is covered.
Is there a price comparison?
M4 PLANT is licensed via CAD Schroer (quotes on request, with a choice of modules). piblaster is a SaaS subscription, monthly or yearly. The classic cost block “Windows license plus hardware for 3D graphics plus setup” disappears with piblaster.

More comparisons
Alternative to PlantEngineer.
PlantEngineer from X-Visual is a strong Visio add-in — but that's exactly the problem if you don't have Visio, don't want Visio, or work on macOS or Linux. piblaster does the same core job without the Visio dependency.
Alternative to Smap3D P&ID.
Smap3D P&ID is a database-driven standalone software for Windows — capable, but with a clear IT footprint: SQL Server, client install, Windows landscape. piblaster delivers the same core result in the browser, without running a database in-house.
When Lucidchart isn't enough for P&ID.
Lucidchart is a solid general diagram tool in the browser. As soon as the P&ID has to carry standards compliance, a BOM, tag logic and reviewer workflows, the tool runs out. piblaster keeps the browser comfort — and adds the P&ID specialisation.
