# Quick reference

Symptom	Cause	Fix
One-click dimensioning wiped your manual dimensions	It clears previous dimensions of the same type	One-click first, then manual
Interior / exterior dimensions muddled	They are two separate types	Mind interior vs. exterior
Elevation dimensions are cluttered with tiny dims	Minimum value not ignored	Enable "ignore minimum value"
Offset / nudge command does nothing	Not a same-direction dimension group	Nudge prerequisite
Material tag shows "?" and won't refresh	—	Use the material tag refresh command
Ceiling material elevation text offset is wrong	Broken on 2018 / 2020	Use another version
Sloped glazing panel tags are misplaced	Revit can't tag them natively	Choose relative-to-floor elevation
Editing one elevation changes all elevations	"Apply to all elevations" was used	Apply to the current elevation only
Sheet viewports are scrambled	Viewport scales weren't set first	Set scale before arranging
Command won't create in a 3D view	Annotations need a drawing view	Switch to the right view

Getting the order wrong wastes the work

One-click dimensioning (and box-select dimensioning) clears previous dimensions of the same type on regeneration.

So: after adding manual dimensions, do not run one-click dimensioning again — it will wipe everything you added by hand.

Correct order: run one-click / box-select dimensioning → top up the few you need by hand → done. If you must redo it, redo the whole run.

Dimensions come in two types — interior and exterior:

Get them the right way round, because regeneration clears previous dimensions of the same type
Mixing them up is exactly how "my added dimensions disappeared" happens
The same distinction applies to partition dimension drawings versus finished-surface dimension drawings

WARNING

The offset behaviour in "nudge up / avoid" only works when the selected dimensions form a same-direction dimension group.

Select dimensions of mixed directions and nothing happens — that's expected.

Version trap

The annotation elevation text offset issue in "ceiling material elevation" is reproducible on Revit 2018 / 2020. Use another version.

Revit itself cannot tag glass sloped glazing panels; the plugin recognises and writes the value in.

Fix: when tagging panels in sloped glazing, choose "relative-to-floor elevation".

If material tags show "?" and won't refresh, run the material tag refresh command.

Viewport layout is arranged automatically based on viewport size and title block size
⚠️ So set the viewport scales first, then arrange — otherwise the result is a mess

WARNING

When adjusting an elevation with multiple storeys, do not use "apply to all elevations" — use apply to current elevation only.

Most annotation commands must be created in a drawing or plan view; they cannot be created in a 3D viewport
"Quick fill" needs an air cavity region box-selected first as its boundary
"Fill colour scheme" and "align headers" are display refinements, separate from the dimensioning commands
Light control lines (fixture connection lines) and point annotation (MEP points) go together; point annotation has V1 and V2 versions — pick as needed
