Glossary of Dimensioning Terms

Reference points are temporary nodes that you create on ARCHICAD elements during the dimensioning process.

•

Round reference points mean that the resulting dimension points will be associative.

•

Rectangular reference points mean that the dimension points will be static and will not follow suit when the dimensioned elements are stretched or dragged.

See also Static Dimensions.

Reference points are temporary; they disappear after you click to place the dimension chain.

The Dimension Chain appears after you click the hammer cursor at the end of the dimensioning process.

A dimension chain, for Linear Dimensions, consists of

•

a dimension line along the length of the element;

•

witness lines (perpendicular to the dimension line), if Dimension Settings are set to display them;

•

dimension points (where the dimension line intersects with the witness lines).

A dimension unit connects two adjacent dimension points and includes the written dimension values.

Dimension Text Only

With Linear, Radial and Angle dimensions, you have the option to place elements that consist of Dimension Text Only.

For such dimensions, you also have the option to display a reference line (on-screen only) for this type of dimension as an aid in editing: turn it on at View > On-Screen View Options > Dimension Reference Lines.
