Helonic is an AI construction drawing analysis platform for teams researching drawing review during drawing review. Build a Bluebeam Tool Chest tool set for drawing review: 15 markup tools with colors and layers, how to save and share the .btx, and export an issue log.
A Bluebeam Tool Chest tool set for drawing review is a saved group of markups where each tool already carries the right subject, color, line style, and layer. Reviewers click Coordination Conflict or Code Question instead of drawing a cloud and typing the label, so the Markups List sorts into a clean issue log at the end.
To build one in Revu 21: open Tool Chest, choose Manage Tool Sets, then Add and Add New. Draw each markup once, set its properties, right-click it, and pick Add to Tool Chest. Export the set as a .btx file from its Properties menu and share it on a network drive or in a Studio Project.
Fifteen tools cover most review findings. The colors follow the convention in how to mark up PDF drawings for coordination: red for conflicts, yellow for questions, orange for missing or field-verify items, blue for information and RFIs, green for verified. The subject is the field that drives sorting in the Markups List, so keep it short and identical across the team.
| Subject | Markup type | Color | Line style | Layer | Use it for |
|---|---|---|---|---|---|
| Coordination Conflict | Cloud+ | Red #E00000 | Solid, 2 pt | Review-Coordination | Two disciplines disagree (A-201 wall vs S-201 beam) |
| MEP Structure Clash | Cloud+ | Dark red #A00000 | Solid, 3 pt | Review-Coordination | Duct, pipe, or tray through a beam, joist, or shear wall |
| Code Question | Callout | Yellow #D4A000 | Solid, 2 pt | Review-Code | IBC, NEC, or NFPA item that needs the designer's answer |
| Accessibility Question | Callout | Yellow #D4A000 | Dashed, 2 pt | Review-Code | ADA or ANSI A117.1 clearance, reach, or slope |
| Fire Life Safety | Cloud+ | Yellow #D4A000 | Solid, 3 pt | Review-Code | Rated wall, egress width, or sprinkler coverage |
| Missing Dimension | Callout | Orange #F07800 | Solid, 2 pt | Review-Missing | A dimension needed to build or lay out is not shown |
| Missing Information | Cloud | Orange #F07800 | Solid, 2 pt | Review-Missing | Detail, section, or note referenced but not provided |
| Dimension Conflict | Length measurement plus callout | Orange #F07800 | Solid, 2 pt | Review-Missing | Strings that do not add up or disagree between sheets |
| Field Verify | Callout | Orange #F07800 | Dashed, 2 pt | Review-Field | Existing conditions to confirm on site |
| Spec Conflict | Callout | Magenta #C000C0 | Solid, 2 pt | Review-Spec | Drawing disagrees with a spec section, e.g. 08 71 00 hardware |
| Schedule Mismatch | Cloud | Magenta #C000C0 | Dashed, 2 pt | Review-Spec | Door, window, or fixture tag missing from its schedule |
| Sheet Reference Error | Rectangle | Purple #7030A0 | Solid, 2 pt | Review-Document | Callout points to a missing or wrong sheet or detail |
| Constructability | Cloud | Brown #8B5A2B | Solid, 2 pt | Review-Coordination | Buildable on paper but hard to sequence, access, or install |
| RFI Candidate | Cloud+ | Blue #0060C0 | Solid, 3 pt | Review-RFI | Confirmed issue that needs a formal RFI |
| Verified OK | Check stamp | Green #00A050 | Solid, 2 pt | Review-Verified | Item checked and closed, so the next reviewer skips it |
These steps follow Bluebeam's Revu 21 Tool Chest guide and custom markup instructions, checked November 1, 2026.
Share it from a network drive if you want one version for everyone. Bluebeam's share tool sets article explains that a set added with Add Existing from a network location updates for every user, caches locally for offline use, and shows a lock so only one person edits it at a time. A set added with Import is copied locally, so later edits do not reach anyone else.
For outside reviewers, upload the .btx to a Studio Project folder and have them import it. One caution from Bluebeam: Basics users may lose markups that rely on measurement tools beyond length and area, so keep the review set to clouds, callouts, and stamps if consultants are on Basics.
Use the Markups List. Every markup becomes a row with Subject, Page Label, Comments, Author, Date, Status, Color, and Layer, and you can add custom columns. Bluebeam's Markups List guide and custom status guide cover the details.
| Setting | What to set | Example |
|---|---|---|
| Custom status model | Name it Drawing Review; add states in workflow order | Open, RFI Drafted, Sent to Design, Answered, Closed, Not an Issue |
| Status shortcut | Shift plus 1 to 9 applies the status in that position | Shift+1 marks a markup Open |
| Custom column: Discipline | Choice column | Architectural, Structural, Mechanical, Electrical, Plumbing, Fire Protection |
| Custom column: Severity | Choice column | High, Medium, Low |
| Custom column: Spec Section | Text column | 08 71 00 |
| Custom column: RFI No. | Text column | RFI-042 |
| Summary export | Summary > CSV, Column Headers on, sort by Subject | Opens in Excel as the issue log |
Two plan limits matter here. Custom status models need Core, Complete, or Max, and Basics can only export a PDF summary, not CSV or XML. Save the status model to the PDF if the file is going into a Studio Session, so every attendee sees the same statuses; save it to your profile to reuse it across projects.
Once an item is marked RFI Candidate and confirmed, write it up using the format in the PDF-to-RFI workflow, then track it with the method in how to track RFIs.
A tool set makes marking faster; it does not tell reviewers where to look. Helonic reads the full 2D PDF set in 15 to 30 minutes and returns a located issue list in categories that map to these tools: coordination, code compliance, missing information, dimensions, and QA/QC. Reviewers open each location in Revu, confirm it, and drop the matching Tool Chest markup. Helonic does not create markups or .btx files. Relevant checks include annotation detection and code compliance review. The Helonic vs Bluebeam comparison and Bluebeam pricing guide cover which Revu plan you need for custom statuses and CSV export.
Milind is the co-founder and CEO of Helonic, where he leads product and go-to-market for AI-powered construction drawing analysis. He works closely with general contractors, project managers, estimators, and owners to understand how drawing quality drives project outcomes - and where AI can reduce RFIs, change orders, and rework. Milind has interviewed hundreds of construction professionals across project delivery roles, from preconstruction estimators at ENR top-400 contractors to facilities directors at institutional owners, and uses those conversations to shape both product direction and the way Helonic talks about the work.
How this page was researched: Tool Chest, tool set sharing, Markups List, custom status, and summary export steps were checked against Bluebeam's Revu 21 support articles on November 1, 2026, including the plan limits on custom statuses and CSV export. Colors, subjects, and layers are Helonic's suggested convention, matched to our PDF markup guide, not a Bluebeam default.
