Angular Dimension from Datum |
Scroll |
Angular dimension from datum is a group of simple angular dimensions, with the first sides matching.
Parameters are set separately for each dimension in the group. If all dimensions must have the same parameters (e.g. arrows of a certain type), call the Remember setting command from the menu of the 
button in the header of the Parameters Panel. You will see a tick mark next to the command name, and selected parameters will be stored for subsequent dimensions.
Dimensions included in the group are independent objects. They can be selected, edited and removed separately.
To create a group of angular dimensions with a common base, do the following.
1.Run the Angular from common base command 
.
2.Set the first side of the angle that is common for the group of dimensions to be created; then create the second side of the angle to set the first dimension in the group. To do this, specify rectilinear objects or points in the graphic area that can be joined to create angle sides (see section Angle sides configuration).
The graphic area will display the angle vertex and dimension phantom.
3.Select the type of the first dimension using the Type group of buttons:
Minimum angle — dimensioning an acute angle,
Maximum Angle — dimensioning the obtuse angle,
Greater than 180 degrees — Dimensioning an angle of greater than 180 degrees.
4.Select how dimension’s extension lines are to be drawn using the Leader lines group of buttons:
Not from center,
From the center.
5.Edit the dimension text, if required. To start working with the dimension text, press any alphanumeric key. See section on editing the dimension inscription...
6.Set the number of decimal places in the dimension text. Details...
7.Set a dimension tolerance. Details...
8.Set up additional dimension parameters, if required: dimension text placement option, arrow display parameters, etc. Details...
9.Set the point defining the dimensional line location.
•If you select automatic, fixed or manual placement of the dimension text, the specified point also defines the text position. After this point is specified, dimension creation is automatically completed.
•If you select to place dimension text on the landing, the specified point defines dimensional line location and start of the leader. In this case, you need to specify one more point – a starting point of the landing. After this point is specified, dimension creation is automatically completed.
10.In sequence, set the second sides for angles and the points that define position of the dimension line and text for the other dimensions in the group. Configure their parameters, if required.

Setting angular dimensions from datum
(angle sides set using segments)
11.If you want to switch to setting a group of dimensions from a different common base, cancel selection of the first side of the angle. To do this, press the Start New Entry 
button or delete the name of the selected segment from the Objects field.
12.To complete operation of the command, click Finish 
.
