BricsCAD CTB Missing or Not Showing: Fix the Plot Style Path
When a CTB is missing from BricsCAD, check the drawing's plot-style model and the configured PlotStyles location before changing the drawing or recreating the file.
Beginner takeaway: A missing CTB is usually a path/model problem, not a reason to rebuild the plot style from scratch.
What you need to understand first
The fastest diagnosis separates ‘file exists’ from ‘BricsCAD can see it’ and ‘this drawing can use it.’
- BricsCAD uses a configured PlotStyles location for plot-style tables.
- CTB and STB are different style-table models.
- A Page Setup cannot select a table BricsCAD does not expose for that drawing/workspace.

Step-by-step workflow
Step 1 — Confirm the file exists
Where: File manager / office standards folder
Do this: Locate the exact CTB and confirm its filename.
Check: You are not chasing an outdated shortcut or email attachment.
Step 2 — Confirm drawing model
Where: Current DWG
Do this: Determine whether the file expects CTB or STB.
Check: The requested table type matches the drawing.
Step 3 — Open Plot Styles Manager
Where: BricsCAD Plot Styles
Do this: Check the actual managed folder/path.
Check: The CTB is in a path BricsCAD uses.
Step 4 — Refresh Page Setup
Where: PAGESETUP > Modify
Do this: Reopen the plot-style list after correcting the path.
Check: The CTB now appears.
Step 5 — Test the table
Where: Preview > calibration sheet
Do this: Apply it to one known Layout.
Check: Expected black/gray/lineweights appear.
What usually goes wrong
| What you see | Likely layer | First check |
|---|---|---|
| CTB exists but not listed | Wrong folder | Use configured PlotStyles path. |
| Only STB appears | Drawing uses named styles | Use correct model/table. |
| Works on one PC only | Different user paths | Standardize PlotStyles location. |
| CTB appears but output unchanged | Not assigned/plot styles disabled | Check Page Setup options. |
Practical example
A consultant sends `office.ctb` beside the DWG. BricsCAD does not automatically know that folder is a plot-style library. Put the file in the managed PlotStyles path or configure the standards location, then reopen the Page Setup and assign it.
What not to do
- Do not create a new CTB with the same name before finding the original.
- Do not convert the drawing between CTB/STB just because a table is missing.
- Do not leave each user with a different unmanaged PlotStyles folder.
Good office standard
Use a shared or deployed PlotStyles location and a simple support checklist: file exists → model matches → path correct → Page Setup assigned → Preview verified.
Quick verification before you move on
- Use one representative drawing or sheet, not a production batch.
- Verify page size, orientation and a known dimension.
- Compare Preview/PDF with the physical output when a printer is involved.
- Save the setting or set only after the result is repeatable.

Frequently asked questions
Why does a CTB work on one workstation only?
The second workstation may use a different PlotStyles path or not have the same file.
Can an STB drawing use my CTB directly?
Not as the same plot-style model. Confirm the drawing standard before converting anything.
Should I restart BricsCAD?
After path/file changes, reopen the relevant dialogs or application as needed, but first fix the actual path/model issue.
