Setting Prohibited Gate Regions

The Prohibited Gate Regions tool is used to block a Gate Location analysis from placing an injection location in the area defined.

Setting Prohibited Gate Regions is an optional prerequisite to running a Gate Location analysis.

Use the Prohibited Gate Regions tool if you want to set a constraint on areas where you do not want an injection location. The areas selected may be based on part or mold geometry, or where a defect caused by an injection location must be avoided.

1. Select (Boundary Conditions tab > Injection locations panel > Prohibited Gate Regions).
2. Select a Selection Method.
   • Tolerance Angle works by the user clicking a point on the model. Adjacent areas meeting at an angle less than the tolerance angle are included in the selection. You can change the tolerance angle in the tolerance setting.
   • Clipped works by the user band-selecting the area they wish to prohibit from having an injection location. When the Near Side Only check box is selected, only areas on the visible side is selected, otherwise areas on both the visible and back sides are selected.
   Tip: You can use a combination of both selection methods when defining prohibited gate regions.
3. Use the mouse to define prohibited regions. Define multiple regions as necessary. The areas defined are added to the Prohibited Gate Regions list.
   Note: To delete a Prohibited Gate Region, select a region from the list and then click Delete.

The areas defined as Prohibited Gate Regions blocks the Gate Location analysis from placing an injection location.
