Description
A revision triangle symbol – the equilateral triangle enclosing a revision letter that flags amended areas on a drawing. This block is drawn with a large clear letter (shown as B) that is quick to edit per revision, and the triangle proportions hold up from 1:1 details to 1:500 site plans.
Place it beside each amendment, cross-reference the letter in the titleblock revisions panel, and your drawing revision trail stays auditable. A tiny block every drawing office needs. Free DWG download for AutoCAD and all compatible CAD software.
