You can activate this selection method by clicking a point on the model. Adjacent areas that meet at an angle that is less than the tolerance angle are included in the selection. The tolerance angle can be changed in the Tolerance setting.
The tolerance setting controls the amount of curve the selection algorithm factors in when selecting an area. The tolerance ranges from 0-89 degrees, with 0 being the lowest amount of tolerance and 89 being the highest amount of tolerance. A low tolerance level selects a narrower range of curve, resulting in a more precise selection. A high tolerance level selects a broader range of curve, resulting in a broader selection area. Modify the tolerance levels to suit your requirements.
The Tolerance Angle selection method is best suited for models that are thick and chunky, or for areas that have many curves and grooves.
The most efficient way of selecting prohibited gate regions is to use a combination of the two selection methods. Multiple prohibited gate regions can be stored and displayed on the same model. Prohibited regions can also be saved with the model, which enables you to duplicate a model with its prohibited gate regions or export the model to Autodesk Moldflow Insight to view or edit the prohibited areas as nodes.
The Prohibited Gate Regions dialog is used to set constraints on areas of the part to block a Gate Location analysis from placing injection locations.
Before running a Gate Location analysis, you can set constraints by defining areas of the part where you do not want injection locations. Prohibited Gate Regions works on both algorithms when using the Gate Location analysis. The prohibited regions can be based on part or mold geometry, or where a defect caused by an injection location must be avoided.
