Hole by Boundary tool

The Hole by Boundary tool allows you to create holes in regions when you are in the process of creating a new model or adding to an existing model. To access this tool, click (Geometry tab > Create panel > Regions > Hole By Boundary).

The Hole by Boundary command is used to define an area to remove from a part surface by the curves that you select.

Dialog element	Explanation
Select region	Allows you to select the region in which you will create a hole.
Select curves	Allows you to select the curves that define the hole you wish to create.
Enable automatic search for connected curves	When this check box is selected, all curves that are connected to the selected curve are automatically added to the selection.
Create as	Allows you to simultaneously create a modeling entity and assign properties to it. For example You can create a curve and assign runner properties to it. You can create a region and assign part surface properties to it. In some cases you have the option to Create as modeling entity. No properties will be assigned. This option may be appropriate if, for example, you are creating curves to construct a region. You must assign properties to the region, but you don't need to assign properties to the curves. Tip: To change the properties of an entity, click Change.
Filter	The filter helps you select a desired model or mesh entity. When you use a filter, the pointer will snap to the specified entity.
