Selection Aids
Several selection aids are available to help you assign dimensions:
• When dimensioning single elements, you do not have to precisely identify the end points of each element. You can click two points on the element that are close to each end point and the cursor will catch to the end points automatically.
• When selecting multiple elements for dimensioning, a filter can be applied to the selection process to selectively exclude items from being considered. Geometry can be filtered based on geometry type, line slope, linetype, pensize, color, and/or linesize. You set up the filter using the Filter options in the Dimension Settings dialog box. The current filter can be enabled or disabled by clicking or clearing the On check box in the Filter settings in the Dimension Settings dialog box.
• A dimension trace appears after you have identified the dimension points of the geometry features you want to dimension. Creo Elements/Direct Drafting then displays a movable dimension trace which shows:
◦ The orientation and location of the dimension(s).
◦ The location of the dimension line terminators.
◦ The length of extension lines.
◦ The dimension text represented by a box.
When multiple elements are selected, the dimensioning trace shows the proposed dimensioning for all the selected elements, allowing you to place the dimensioning text for all of them with a single click.
