Mask Panel

Location: Tool page or 1D page > Connectors module

Masking can be useful to reduce the number of entities displayed. With fewer entities on the screen, it is easier to select the desired elements or lines.

It is also possible to speed up processing time by masking off portions of a large model while you are working on a smaller, localized section of the model.

When masking connectors, you can choose to mask the corresponding realized FE by selecting the mask realized FE checkbox.

Mask Subpanel

Option	Action
(entities switch)	Select the entities to mask. Some collector-type options, such as comps, enable a series of checkboxes to allow you to select entities contained within the collectors. When you select elems, click the switch to change the selection mode. elems Select individual elements, or select all of the elements contained by a component or on a surface. Figure 1. Example: Elems Selection faces Select all of the elements on 2D and 3D faces. If there are discontinuities on a 2D face, then only the elements in between the discontinuities will be selected. Figure 2. Example: Faces Selection 2D faces ext Select all of the elements on a 2D face that contain discontinuities. Figure 3. Example: 2D Faces Ext Selection
include realized fe	Mask realized elements along with their related connectors. Note: Available when masking connectors.
face angle / individual selection	face angle Angle between the normal of facets that share an element edge. A facet can either be a shell element itself, or one of the faces of a solid element. The normal of triangular facets is that of the plane defined three corner vertices. Whereas, the normal of quadrilateral facets is calculated by taking the cross-product between its two diagonals. This special treatment for quadrilaterals is because a warped shape does not lie completely on a plane. individual selection Select individual elements on a face or select individual free/shared edges of elements.

Unmask Subpanel

Option	Action
(entities switch)	Select the entities to unmask. Some collector-type options, such as comps, enable a series of checkboxes to allow you to select entities contained within the collectors. When you select elems, click the switch to change the selection mode. elems Select individual elements, or select all of the elements contained by a component or on a surface. Figure 4. Example: Elems Selection faces Select all of the elements on 2D and 3D faces. If there are discontinuities on a 2D face, then only the elements in between the discontinuities will be selected. Figure 5. Example: Faces Selection 2D faces ext Select all of the elements on a 2D face that contain discontinuities. Figure 6. Example: 2D Faces Ext Selection

Command Buttons

Button	Action
mask	Hide selected entities.
reverse	Reveal any hidden entities, while hiding any visible ones, within the constraints of your selection.
reverse all	As for Reverse, but affects all entities, not just your selection.
mask not shown	Mask all entities that currently lie outside the current field of view (beyond the edges of the graphics area).
unmask all	Reveal all entities.
unmask	Reveal the selected entities.
unmask shown	Unmask all entities that currently lie inside the current field of view (within the boundaries of the graphics area).
reject	Undo the most recent mask operation.
return	Exit the panel
