There are multiple ways to select 3D parts in the 3D Model Tree tab and 3D Model Window.
Select the desired parts in the 3D Model Tree section of the 3D Model Tree tab.
Note: Selecting a part in the tree will select all of the children parts in that branch of the model tree.
Click Select from the Mouse Interaction menu.
You can also use the ALT key to select parts without using Select.
The direction the selection area is drawn affects whether a part is selected when it is enclosed within or intersects the area.
Single parts can be selected or unselected after drawing a selection area by holding down SHIFT or SHIFT+CTRL when clicking on the part.
Selected parts will be highlighted in the 3D drawing area and in the 3D Model Tree to show they are selected.
3D parts can be selected, copied, and then pasted to create a new 3D model window. This is useful if you want to create a new 3D model window of a small section of a larger model, for example to use as an RFI.
To paste parts into a new 3D model window:
Click and drag a rectangle to define the area of the 3D model to be pasted. The Add 3D Content dialog box appears.
Use the 3D Editor to the edit the size or location of the new 3D model window.
