Editing a List of Elements

This task shows how to edit a list a elements within any other command allowing multi-selection for input elements, when the list is not already explicitly available from the dialog box. In the latter case (spline, join, fill, loft, split, and so forth) Add/Remove/Replace buttons are usually available, along with a contextual menu on the elements from the list.

The list edition capability is available with the following commands:

	Intersections
	Projections
	Extracting
	All transformations: translation, rotation, symmetry, scaling, affinity and axis to axis.

Open the Projection1.CATPart document.

Select the Extract.1, Translate.1 and Translate.2 elements and click the Projection icon .

The Projection Definition dialog box appears, indicating that three elements have been selected.

Click the icon to display the Element list dialog box. It allows you to:

	view the selected elements
	remove any element clicking the `Remove` button
	replace any element using the `Replace` button and selecting a new one in the geometry or the specification tree.

Select Translate.2 in the list and click the Remove button.
Click Close in the Element list dialog box to return to the initial command: projection in this case.

The Projection Definition dialog box is updated accordingly: only 2 elements are identified as being selected for projection.

Select the surface as the support and click OK.

The two selected elements have been projected onto the surface and two separate elements appear in the specification tree. Being distinct elements, they be edited separately.
