Key Terms
DefinitionTerm
A dimension that is aligned to extension lines and read from the bottom or
right side of the drawing.
baseline dimension
Line in the center of a symmetrical object.centerline
A standardized frame that is used for technical drawings.drawing border
Range of tightness or looseness in mating parts (for example shafts or holes).
Tolerances in these dimensions are expressed in standard form.
fit
Name of the selected fit (for example, H7).fit name
An option where you determine a selection set of dimensions and edit them
together.
multi edit
Power Dimensioning is a tool for generating linear, radial, angular, and diameter
dimensions, which minimizes the number of the individual actions required
Power Dimensioning
while generating a dimension. Power Dimensioning selects the type of linear
dimension (horizontal, vertical, or aligned), based on the selected point, and
the dimensions of the drawing can have a uniform style using the distance snap.
Command for deleting. Use Power Erase when you delete part reference numbers
or dimensions that were created with Power Dimensioning and Automatic Di-
mensioning.
Power Erase
A title block contains a series of attributes. Some already have values. The pre-
assigned values can be modified, and the vacant attributes can be completed
with new values.
title block
The total amount by which a given dimension (nominal size) may vary (for ex-
ample, 20 ± 0.1).
