When an engineer goes to the field, they discover that their computer is no longer a workstation. The computer on site is usually locked down by company policy: no new software can be installed, no license is available, cloud services are blocked. Add a weak field connection and the question "who is allowed to see this file?" and classic CAD is almost unusable on site.
The three walls in the field
- Install permission: no software can be installed on the on-site stations; a tool that requires an install is a tool that cannot be used on site.
- Weak connection: the field office works over the local network; when the connection drops, everything cloud-based stops.
- The going file: every cloud transfer is company data leaving the device. In a client's facility, uploading the client's files to a cloud is often unacceptable.
The fix: no install, the connection is optional, the file stays home
EupCAD gets past all three walls at once:
- No install — a modern browser is enough. Nothing is installed on the on-site station; you type the address and the drawing opens.
- The connection is optional — the application also works offline. When the connection drops, drawing, reports and file access continue; when it returns, you pick up where you left off.
- The file stays home — the project is created in the browser and downloaded as a single file. It is never uploaded to a server; if it is not meant to be shared, it is never sent. A panel drawn in a client's facility stays on the client's device.
Practical scenario: a change order on site
On site, the client requests a circuit change. In the classic flow: the engineer on site notes the change, returns to the office, updates the drawing, and regenerates the lists. Days pass; meanwhile the field works from the old schematic.
In the EupCAD flow: the change is made on site, in the browser. Even offline, the drawing is updated and the BOM and terminal schedule are re-downloaded. By the end of the day, the field is working from the current drawing and the current lists — the change produced office-grade output without a trip to the office.
Next step
In the demo project (ZONE1_PUMPS), browse the pages in the browser; then turn off your connection and reload the application. See that drawing and report access continues.
