Use the 
Volume Extract tool in the Analysis group on the Prepare tab to create a solid based on the volume enclosed by a single body or set of bodies (including meshes). A solid named Volume is created in the Structure tree
, and the bodies used to generate the volume are temporarily transparent when the volume is created.
If a surface intersects all of the edges you select to enclose the region, it will be used to cap the created volume. You can create cleaner caps by placing surfaces at each of the edges you use to define the enclosed region.
|
If an edge will be removed when you use the Volume Extract tool, that edge will flash red and you will receive a warning message. This can happen when you select a capping edge that will be removed when it is merged with the rest of the model. The highlight identifies the problem so you can pick a different edge. |
Click the Volume Extract tool in the Analysis group of the Prepare tab.
Click the Select Edges tool guide to select the edge loops that enclose the volume of the area.
You can double-click to select more than one contiguous edge. You can also click a selected edge to deselect it. Select edge loops only that you intended to use to enclose the volume area. If you hover over a face that contains internal edge loops, the edge loops are highlighted. Click the face to select the highlighted edge loops.
If necessary, click the Select Cap Faces tool guide to cap a face.
(Optional): Select the Preview inside faces checkbox to activate the Preview slider. Your model immediately updates to paint a preview of the inner faces shown in red at 100%. Move the slider to the left and right to preview the faces, and see a progression of how the faces were captured.
When previewing the faces, all Select tools and context menu Select tools, as well as all Volume Extract tool guides, are disabled until the Preview checkbox is turned off.
Click the Select Seed Face tool guide and select a face inside the volume area. The Select Seed Face tool guide is used to select a face to determine the inside of the enclosed volume. You only need to use this tool guide if the Volume Extract tool fails to correctly identify the inside of the volume.
Click the Complete tool guide.
SpaceClaim creates a surface part based on the volume you defined.
Right-click the volume part (named Volume by default) in the Structure tree. Select one of the following commands:
Regenerate Volume Body as Created updates the volume body based on objects that were visible when the volume was created (regardless of their current visibility). Use this option for simple regeneration.
Regenerate Volume Body in Context updates the volume body based on objects that are currently visible in the design area. Use this option to remove bodies from the volume calculation.
The following tool guides help step you through the process:
|
|
The Select Edges tool guide selects edge loops that enclose a region. Edges are used to stop the propagation of face selection, emanating face-wise outward, starting at the selected seeds. |
|
|
The Select Faces tool guide activates by default when you select the Volume Extract tool, and selects faces whose edges seal an enclosed region. This is a shortcut to selecting all the edges that are detected in a face. You can Ctrl+ Select multiple seed faces, and then choose to click on a different tool guide. Once you create a volume, the Select Faces tool guide resets by default. |
|
|
The Select Cap Faces tool guide selects optional capping faces. This is important when an internal edge loop is either not simply fillable, or when you want some non-standard fill geometry to be created. |
|
|
The Select Seed Face |
|
|
The Complete tool guide creates the volume solid based on the edges and seed face you select. |
