Changing Radial Dimension References on Arcs
You can change the reference of an existing radial dimension from one arc to another, provided the new
arc is concentric with the original arc.
1
Select a radial dimension.
A blue square drag control appears at the end of the dimension.
2
Drag the control to another arc.
A valid concentric arc highlights when you place the cursor over it.
Arc Length Dimensions
You can dimension arc walls to obtain the overall length of the wall.
1
Click Drafting menu
➤
Dimension, or on the Drafting tab of the Design Bar, click Dimension.
2
On the Options Bar, click
(Create Arc Length Dimensions).
3
For Prefer, select a snap option.
For example, choose Prefer wall faces to have the cursor snap to the inside or outside wall face.
This aids in selecting the radial point.
4
Place the cursor on the arc and click to select the radial point.
5
Select the end points of the arc and move the cursor up and away from the arc wall.
6
Click to place the arc length dimension.
Baseline and Ordinate Dimensions
Baseline dimensions are multiple dimensions measured from the same baseline.
Ordinate dimensions measure the perpendicular distance from an origin point called the datum to an
element. These dimensions prevent escalating errors by maintaining accurate offsets of the features from
the datum.
