Selection of 3D Elements |
|
Any 3D element can be selected in a 3D view window (considering filters), in the 
3D model tree or in the 
Model elements window. Elements of some types may also be selected in other tool winows.
The selection is performed in accordance with general principles described in the Selection of Elements section. During selection you may use object snapping and hints.
In order to select some of the 3D elements (e.g.: 3D profiles, workplanes), you have to place the cursor over their contour line. In order to select a body, you may place the cursor over any part of the body, using the 
Select Operations filter. 3D elements may overlap each other. Therefore, it is necessary to correctly orient the scene, so that the desired element is in front of others.
Unlike 2D window, by default, frame and curve selection in 3D windows may be performed only using the right mouse button 
, as the left button 
is assigned to rotation of the 3D scene. Also, this method of selection has additional options in 3D windows.
By default, only visible elements may be selected in 3D window. However, you can allow the selection of invisible elements if necessary (Document Parameters > 3D > View > Selection > Elements Selection > All). Keep in mind that some elements are visible in 3D window only if the Show in 3D Window checkbox is enabled in their parameters (e.g.: workplanes, 3D sections). Unlike 2D elements, 3D elements may be not only 
Hidden, but also 
suppressed.
When working with assemblies containing nested assemblies, selecting bodies in 3D window selects the top-level fragments by default. In order to select fragments of nested assemblies, activate the 
Select operations by created faces option in the Filter toolbar;
Selecting elements within a command
Command for creation of operations and 3D constructions usually require to select various elements existing in the 3D scene. E.g.: the Extrusion command requires to select an extrusion contour and allows to optionally select a vector or two points defining a direction of extrusion, objects defining extrusion boundaries, a point or a plane for calculating a length of extrusion and a body for an automatic Boolean operation. The selection can be performed after activation of corresponding automenu options or input boxes of the command's parameters window. It activates a suitable set of element's type filters and geometry type filters. Other than that, the selection is performed in the same way as in the command standby mode.
Within a command 3D elements created by 2D elements can be selected by selecting a parent 2D element. E.g.: if you need to use a 3D Node constructed by two projections as an origin within the LCS creation command, it is enough to click one of the parent 2D nodes, so the child 3D node will be selected in result.
Unlike the command standby mode, you can not call an element's contextual menu by clicking on an element in the 3D window. Instead of invoking a contextual menu, it cancels the last action. However, you can still call the contextual menu in the model tree and model elements window.
In some commands, you may also use the Select Other Element option.
