Units and Dimension Format

The Units & Precision section controls how dimensions display across the entire app. It does not change the underlying measurements of your project - a 10-foot wall is the same 10-foot wall whether shown as 10'-0" or 3.05 m. The setting is purely a display preference.

Unit System

A two-option dropdown:

• Imperial - feet and inches family.
• Metric - meters, centimeters, millimeters family.

Whichever you pick determines what options the Dimension Format dropdown below it offers, and whether the Fraction Precision dropdown is visible.

The Unit System affects every place a dimension is shown:

• Tape dimensions on the canvas
• Saved dimension lines
• Wall lengths in entity panels
• The Value Command Bar (the numeric entry that appears when you draw or move)
• Print output dimension labels
• The Schedule columns where lengths appear

Dimension Format

Different options appear based on Unit System.

Imperial:

• Feet-Inches (default) - e.g. 8'-6" or 8'-6 1/2"
• Inches only - e.g. 102" or 102 1/2"
• Decimal Feet - e.g. 8.5'

Metric:

• Meters - e.g. 2.59 m
• Centimeters - e.g. 259 cm
• Millimeters - e.g. 2591 mm

Pick what matches the drawings you produce. Architectural plans in North America typically use Feet-Inches. Cabinet shops sometimes prefer Inches only. European plans typically use Millimeters.

Fraction Precision (imperial only)

This dropdown is hidden when Unit System is set to Metric. It only applies to imperial display.

Options:

• 1/16" (default)
• 1/8"
• 1/4"
• 1/2"
• 1"

This controls how dimensions round for display. The underlying geometry is still full precision - the rounding only affects what shows on screen and in print. A wall that's actually 8'-6 3/32" displays as:

• 1/16" precision: 8'-6 1/16" (rounded to nearest 16th)
• 1/8" precision: 8'-6 1/8"
• 1/4" precision: 8'-6 1/4"
• 1" precision: 8'-6"

If you draw walls by snapping to other features (corners, midpoints), you'll rarely see odd fractions. If you free-draw, you'll see the rounding more often.

What it doesn't change

• Project geometry - changing units doesn't resize anything. Walls, fixtures, and rooms stay at their exact dimensions.
• Stored values - the underlying numbers are always in millimeters internally. Switching display units is purely cosmetic.
• Other modes - Customer mode and Contractor mode each have their own Unit System and Dimension Format preference. Setting Imperial in one mode doesn't set it in the other.

Switching mid-project

You can switch units at any point in a project. Nothing breaks. Existing dimensions re-render in the new format immediately - no re-entry needed.

Common workflow: draft a plan in Imperial because that's what you know by feel, then flip to Metric for the print pass because the client requested metric drawings. Print, flip back. The project file is the same throughout.

Custom fixture sizes

When entering custom fixture dimensions (vanity width, island length, custom rectangle size, etc.), the input field accepts whatever format matches your Unit System. The field also accepts common shorthand:

• Imperial: 8'6, 8' 6, 8'-6", 8'-6 1/2", 8.5', 102, 102", 102 1/2"
• Metric: 2591 (bare number = mm), 2591mm, 2.59m, 259cm

The Value Command Bar (the numeric entry while drawing) accepts the same shorthand.
