To enter a distance

Enter H1 to refer to the frame height.

Enter W1 or H1 to refer to the width or height of frame 1.

Read W1 or H1 as width of frame 1 or height of frame 1. Similarly W2 is the width of frame 2, and H3 the height of frame 3.

A numeric value from H1 or W1 can be added or subtracted.

When using Sub units for English values, place the distance between square brackets.

For example: [3:7 3/16] Leave a space between the sub units and the fractions. The space is shown as an underscore ( _ ) in the command line. H1 or W1 can be multiplied or divided and numeric values can be entered.

W1/4	The width of frame 1 divided by 4.
W1-[2:5 1/16]	The width of frame 1 minus a distance (in sub units).
W1 30	The width of frame 1 minus a distance (in working units).
H1*2	Twice the height of frame 1.
4:7 3/16	A distance (in sub units).
450	A distance (in master units).

The following mnemonics can be entered in a distance field:

Mnemonic	Distance
RH	Horizontal recess.
TH	Horizontal tolerance.
RR	Roller Blind recess.
WI	Thickness interior wall.
CA	Thickness cavity.
WE	Thickness exterior wall.
RV	Vertical recess.
TV	Vertical tolerance.

Note: Mnemonic values can be used when creating parametric frames. A mnemonic value is an arithmetic function used as a substitute for a real number. For example, a dimension (or distance) for frame width can be defined as W1/3, where width is divided by three. The advantage of using mnemonic values is to enable a parametric frame to maintain its proportions regardless of modifications to the frame size.
