Select by Solid
Source file: select-by-solid.htm
Select by solid allows you to select all objects associated in some way with a particular solid surface object. Selection policies give you options for comparing spatial relationships. For example, you can select all objects inside, outside or intersecting a particular solid shape, or all those that are either outside or intersecting the particular solid.
Note: For the Select by solid function to work, the object used as the selection policy’s reference must be a closed solid. That is, it must not have holes.
To select by solid, proceed as follows:
-
Select all objects that are to be filtered by the selection policy.
-
On the Home ribbon tab, go to the Selection group. From the Select By drop-down list, select
Solid. -
Click on the particular solid surface to reference in the view window. It will auto-populate the Solid of the panel. Alternatively, drag the solid surface from the project explorer into the Solid field.
-
Ensure the required Selection policy is selected from the drop-down menu. Options are as follow:
- Inside
- Inside and intersecting
- Intersecting
- Outside and intersecting
- Outside
-
Click OK or Apply to process.
-
The objects meeting the selection policy will remain selected. Others will be de-selected.
-
Where two criteria are used in the selection policy, an object only has to satisfy one criterion to be selected.
Objects intersecting, inside and outside the main complex solid surface (translucent orange), to be used as the reference solid.

Selection policy set to look for objects either outside the reference solid or intersecting it.
The selected objects met the criteria of the selection policy: the line and the tunnel intersect the main complex solid and the pink polygon lies outside the complex surface. The points are inside the complex solid, so not selected.
