Redimension Elevation

Redimension Elevation puts a fresh set of A+ Tools dimensions on a curtain wall in the elevation or section view you have open — overall, detailed and segment dimensions, with your letter substitutions and text overrides — without creating new views or sheets. Use it after you have changed a wall (moved a grid line, swapped a door, re-divided the panels), or to dimension a wall in an elevation you made yourself.

Before: the panels were re-divided and the old dimensions are gone. After: a complete new set.

Before you start

• Open an elevation or section view. The button is greyed out in any other kind of view (plans, 3D, sheets, schedules, drafting views…). The dimensions are always placed in the view that is active when you start the command.
• The dimension types must exist in the project. If the Overall or Detailed dimension type saved in the settings is missing from the project, the Dimension Settings window opens before you can pick a wall.
• These settings are separate from Create Drawing. Redimension Elevation has its own settings profiles. To get exactly the dimensions your Create Drawing profile produces, load that profile into the Dimension Settings window with the profile bar — see How these settings relate to Create Drawing.
• You need to be signed in (or on a trial). On a Free licence each re-dimensioned wall uses credits.

What is removed and what is created

The new dimensions are:

“Left” and “right” are as you see the wall in the view, whichever way the wall was drawn.

The A+ Tools dimensions and their offsets from the wall.

Step by step

1. Open the elevation or section view that shows the curtain wall.
2. Click A+ Tools › Curtain Wall Utilities › Redimension Elevation.
3. On the Options bar, decide on Clear (tick it to replace the dimensions that are there) and Multiple. Use Settings to check the dimension settings.
4. Pick the curtain wall. The status bar reads Select curtain wall to re-dimension (Press Escape to finish). Only curtain walls can be picked. After the first pick, Multiple, Clear and Settings are locked for the rest of the run.
5. Single mode: the command finishes after the wall. Multiple mode: pick the next wall in the same view, and press Esc or click Finish when you are done.

The whole run is one entry in Revit's undo list (Redimension Elevation(s)).

The Options bar

The Options bar while Redimension Elevation waits for a pick (Revit 2026).

Multiple and Clear are remembered until you close Revit (Multiple is shared with the other A+ Tools commands). In Revit 2027 the same controls appear as an A+ Tools panel on the Modify tab, with a large Settings button.

Tip — Several walls in one view. Clear only touches the wall you pick, so you can tick Clear and Multiple and re-dimension every wall in a view in one run — each wall keeps the new dimensions it just got.

Finishing a run and Esc

• Esc before any wall is done ends the command with no changes.
• Esc in Multiple mode after at least one wall opens Commit Changes? — You have re-dimensioned N curtain wall elevation(s). Choose Yes - Commit changes and finish, No - discard (undoes the whole run) or Continue (Continue re-dimensioning).
• Finish keeps everything without asking.

Commit Changes? after pressing Esc in Multiple mode.

Running with a specific profile from the ribbon

When a Redimension Elevation profile has Add as menu item to ribbon switched on, the button becomes a drop-down with one item per flagged profile, a separator and Settings… (Configure this command's settings and profiles, then run it). A profile item selects that profile and runs the command; Settings… opens the Dimension Settings window and runs the command when you click OK. See Settings profiles and repositories.

Settings

The Dimension Settings window

Open it with Settings on the Options bar, Settings… in the ribbon drop-down, from the Settings Manager, or automatically when a dimension type is missing.

At the top is the shared profile bar — choose, create, rename, delete, load and save profiles and switch Add as menu item to ribbon on or off. It is described in Settings profiles and repositories. Below it the window has two tabs.

Tab: Dimension Types

Dimension Settings — the Dimension Types tab.

Dimension Types

Tip — Offsets are distances in the model, not on paper. At 1:50, a 400 mm offset is 8 mm on the sheet. Keep the order detailed < segment < overall so the chains stack neatly.

Standard Panel Size

Tab: Dimension Text Overrides

This tab is the twin of the Overrides and Substitutions tab in the Create Drawing settings: same fields, same rules. Use it to add text to dimension values, replace them, or swap repeated values for letters.

Dimension Text Overrides — an overall dimension selected.

Select Dimension Type to Override — pick which dimensions the fields below apply to. The list is grouped:

“Bottom” is the detailed chain below the wall (panel widths); “Right Side” the detailed chain on the right (panel heights). For a panel group, a line under the list repeats what it applies to, e.g. Applies to all panels of type: Glass Panel.

The tip under the list: Use {parameter name} for instance parameters and [parameter name] for type parameters. Parameters are resolved at runtime. — see Parameter values in overrides.

Override fields (all items)

Letter substitution (door, other and glass items)

Glass panel items have an extra Don't apply to column beside each field, so you can treat standard and lettered panels differently:

Glass panel overrides with the Don't apply to check boxes.

Clear All Text Overrides (button) — empties every override on every item, switches letter substitution off for all groups and resets the base letter to a. There is no confirmation; click Cancel to throw the change away.

Configured Overrides — a summary of every item that has something set, one row per item, e.g. Prefix: "ca " or Equal measurements will be substituted with a letter., with notes such as (Does not apply to standard panels). Remove on a row clears that item. With nothing set it reads No overrides configured.

Parameter values in overrides

Any override field can contain parameter tokens that are filled in when the dimensions are made:

• {Parameter name} — an instance parameter, e.g. {Mark}, {Comments}.
• [Parameter name] — a type parameter, e.g. [Type Mark], [Width]. [Type] gives the type name.
• Overall and segment dimensions read the parameters of the curtain wall; panel dimensions (glass, door, other) read the parameters of each panel.
• Parameter names are not case-sensitive. If a parameter does not exist or is empty, the token is left in the text as typed (e.g. {Mark}), so you can see what to fix.

Examples:

How these settings relate to Create Drawing

• The dimensions are made exactly as in Create Drawing: same dimension types, offsets, letter substitution and text overrides, applied in the same order.
• But each command has its own profiles. Changing the Create Drawing settings does not change Redimension Elevation, and the other way round.
• To make Redimension Elevation match a drawing, open Dimension Settings and use the profile bar to load the Create Drawing profile you used. It brings across the dimension types, offsets, standard panel width, overrides and substitution — and the glass panel family, which decides what counts as glass. This window has no field for the glass family; the Applies to line shows which family the current profile uses.

Footer and validation

When something is wrong, OK and Apply show a Validation Errors message — Some settings did not pass validation. — with a bullet list, and the fields concerned are outlined in red:

Tips

Tip — After Create Panel Divisions, always redimension. Dividing panels removes the wall's dimensions in the view; run Redimension Elevation in the same view to get a complete, correct set.

Tip — Replace, don't stack. Tick Clear when the view already has A+ dimensions you want to replace. Without it you get a second set on top of the first.

Tip — Hand-placed dimensions. Clear removes every dimension that measures the picked wall — including ones you added yourself to its grid lines, panels or mullions (a sill height, a setting-out dimension). Dimensions that only measure other elements stay. Add your own wall dimensions again afterwards, or untick Clear and delete the old A+ chains by hand.

Tip — Works on your own views too. Any elevation or section that shows the wall square-on can be dimensioned — not only views made by Create Drawing.

Tip — Walls with rows. On a wall split into rows (for example by a vertical pattern), the width overrides and letters follow the bottom row of full-height panels — the panels you read at floor level. Low strips along the floor are skipped.

Tip — A profile per drawing style. Make a profile with letter substitution for tender drawings and one with plain numbers for workshop drawings, and put both on the ribbon.
