Dimension Text Height Tool

Dimension Text Height Tool v1.1 — AutoLISP + DCL

Resize selected dimension text with an easy-to-use dialog. Enter your desired height in inches, see its decimal value, and let the tool calculate the required DIMTXT setting for each selected dimension’s overall scale.

For example, 4.5″ ÷ scale 48 = 0.09375 DIMTXT.

Features

• Update one dimension or multiple dimensions.
• Enter decimal or fractional-inch heights.
• Preview the calculated decimal DIMTXT value.
• Calculate each selected dimension separately for mixed-scale selections.
• Choose desired drawing height or direct DIMTXT mode.
• Handle fixed-height text styles by creating a variable-height copy.
• Optionally remove inline text-height overrides.
• Skip dimensions on locked layers.

Ideal for adjusting architectural dimension annotations without editing the shared dimension style.

Your download includes

• AutoLISP routine and matching DCL dialog.
• Installation and operating instructions.
• Gray DCL preview image.

Easy setup: Load the LISP using APPLOAD, then type DTH.

Compatibility: Designed for Windows AutoCAD 2002 with Visual LISP/ActiveX. Source and calculations checked; execution inside AutoCAD 2002 has not yet been tested.

Please note: Desired-height mode assumes one drawing unit equals one inch and sets nominal text height in the drawing, not printed paper height. Automatic or zero-scale dimensions require direct DIMTXT mode. Exploded dimensions and dimensions nested inside blocks are excluded.
