Elements missing or not visible in Revit
Use a structured visibility check instead of changing random settings.
Medium
Revit
Visibility
Common issue
Likely causes
- Hidden in view or category
- View template override
- Filters or workset visibility
- Phase or design option mismatch
- Crop region, section box, or view range problem
Checks to perform
- Use Reveal Hidden Elements
- Check the applied view template
- Review Visibility/Graphics and filters
- Check workset, phase, and design options
- Test in a temporary 3D view
Recommended action
Identify one known missing element and trace its category, workset, phase, and host conditions before wider edits.
Linked model not showing correctly
A loaded link can still display incorrectly because of view-specific settings.
Medium
Revit
Links
Likely causes
- Revit Links visibility set incorrectly
- By Linked View referencing the wrong linked view
- Graphic overrides or halftone making content unclear
- Linked model positioned incorrectly
Checks to perform
- Open Visibility/Graphics > Revit Links
- Check whether the link is By Host View, By Linked View, or Custom
- Review the selected linked view if relevant
- Check location and positioning assumptions
Recommended action
Temporarily switch to Custom visibility to isolate whether the problem is view-driven rather than model-driven.
Worksharing or sync issues
Failures in worksharing often come from local/central misuse or ownership conflicts.
High
Revit
Worksharing
Likely causes
- Users working incorrectly against the central model
- Ownership or borrowing conflicts
- Local file corruption or poor sync habits
- Permissions or file path issues
Checks to perform
- Confirm users are opening the correct local or cloud workflow
- Check ownership of edited elements or worksets
- Save locally and retry sync
- Review whether the issue is user-specific or model-wide
Recommended action
Stop random retries. First identify whether the issue is ownership, permissions, or model health.
CADmep placing wrong items or missing services
Most CADmep placement issues come from services, content, or database setup.
High
CADmep
Services
Likely causes
- Wrong profile loaded
- Incorrect database path
- Service template not aligned with standards
- ITM content missing or inconsistent
Checks to perform
- Confirm the correct profile is open
- Check the fabrication database path
- Review service templates and item folders
- Test with a known approved item
Recommended action
Fix the content source and service logic first. Do not let users work around poor setup manually.
CADmep report, spool, or PCF export problems
Output failures usually indicate upstream content or connectivity issues.
Medium
CADmep
Outputs
Likely causes
- Bad numbering logic
- Inconsistent content
- Poor connectivity
- Wrong selection scope
Checks to perform
- Check item consistency and numbering rules
- Confirm the selected objects are correct
- Check connectivity before PCF export
- Run a small test output first
Recommended action
Treat report/export issues as a model-quality problem first, not just a command failure.
ACC / Autodesk Docs access or folder issues
Many cloud workflow problems come from permissions and folder misuse.
High
ACC
Permissions
Likely causes
- User not invited or permissions incorrect
- Wrong folder being used
- Project structure unclear
- Expected publish route not understood
Checks to perform
- Confirm the user can access the intended project
- Review folder permissions
- Check whether the model or file is in the correct area
- Confirm whether the issue is viewing, editing, or publishing related
Recommended action
Clarify folder purpose and permissions before re-uploading or duplicating files.
PDF or DWG output looks wrong
A correct model view can still produce poor output if the issue settings are wrong.
Medium
Documentation
Output
Likely causes
- Bad print/export setup
- Unexpected lineweight or layer mapping
- Wrong title block or revision information
- View not checked after export
Checks to perform
- Check sheet data and revision information
- Review print/export configuration
- Test output on one sample sheet first
- Open the final exported file and review it properly
Recommended action
Never assume the issue file is correct just because the live view looked correct.
Element visible in 3D but not in plan
This usually points to a view range or plan-view-specific visibility issue.
Low
Revit
Plan views
Likely causes
- View range cut plane issue
- Bottom/top clip mismatch
- Category visibility or filter override
Checks to perform
- Compare the affected plan to a working plan
- Open View Range
- Check category visibility and filters
Recommended action
Treat it as a plan-view setting issue first, not a missing-model issue.
