Frequently asked questions
What is this symbol library?
A browsable reference of our original construction markup symbols — electrical, CCTV, security, fire alarm, AV/data, MEP and estimating — each with a stable ID, abbreviation, drawing layer and use case.
Is the library free to browse?
Yes — browsing and inspecting every symbol here is free and requires no account. The paid BTX packs contain the import-ready Tool Chest files; this page is the open reference.
How do I use these symbols in Bluebeam Revu?
Buy the trade pack, download the BTX file, then in Revu open the Tool Chest, choose Manage Tool Sets and Import the .btx file. Every symbol appears as an organised, reusable tool.
What is a BTX file exactly?
A .btx file is a Bluebeam Tool Chest export: an XML document containing tool definitions with compressed appearance streams. Our free BTX tools can open, validate and report on any .btx file.
Do the symbols follow a naming standard?
Yes. Every symbol carries a stable CMT ID (for example CMT-ELEC-001), a short abbreviation, and an assigned drawing layer so markups stay organised across teams.
Can I see the symbols before buying?
Yes — browse this library freely, and download the free sample pack to test import behaviour in Revu before purchasing.
Which pack should I start with?
Start with your own trade. If you work across several disciplines, the bundles cover multiple packs at a better price — the comparison page shows every option side by side.
Are these symbols royalty-free for commercial work?
Yes — purchased packs are licensed for commercial project use. The licence terms page details individual and team scope.
