Modeling Preferences > Hole Analysis

Access: Invoke this function from one of the following locations:

Select the Preferences button from the Quick Access Toolbar, or
Select Tools > Main Tools > Preferences from the menu bar.

Navigate to Modeling > Hole Analysis.

Set the default values for hole analysis operations. Set the default parameters for each type of analysis performed in the Hole Safety Distance function. In addition, set the parameters that define the default tolerances to identify holes and to create groups of similar holes.

The Hole Analysis dialog is displayed.

Interaction

Set the default Hole Safety Distance parameters. These parameters set the default Min. Distance threshold and Color for each type of analysis performed in the Hole Safety Distance function. If the distance between the objects being analyzed is less than the Min. Distance value, then these are considered as collisions.

Cooling Holes vs. Active Faces	Checks the minimum defined distance of cooling holes against active faces (faces touching the plastic).
Cooling Holes vs. Other Faces	Checks the minimum defined distance of cooling holes against other faces (anything that is not a hole or active face).
Cooling Holes vs. Cooling Holes	Checks the minimum defined distance of cooling holes against cooling holes.
Cooling Holes vs. Regular Holes	Checks the minimum defined distance of cooling holes against regular (non-cooling) holes.
Regular Holes vs. Regular Holes	Checks the minimum defined distance of regular holes against regular holes.
Regular Holes vs. Active Faces	Checks the minimum defined distance of regular holes against active faces (faces touching the plastic).
Regular Holes vs. Other Faces	Checks the minimum defined distance of regular holes against other faces (anything that is not a hole or active face).

Set the default Hole Analysis parameters. These parameters define the default tolerances to identify holes and to create groups of similar holes. These parameters also appear in the Drafting Table of Holes preference and the NC Tolerances preference. The default values here are the same as those defined in the NC preferences.

Angular Tolerance	Determines the maximum angular deviation value of segments within a hole which defines them as part of the same hole. This means that if two faces of the same hole are not on the same axis (within the angular tolerance), they are not defined as being part of the same hole. ExampleExample
Diameter Tolerance	Determines the maximum deviation of the diameter value of corresponding segments of different holes which defines them as the same type of hole. This means that if the diameters of corresponding segments of different holes are not the same (within the diameter tolerance), they are not defined as the same type of hole. Example: Example:
Hole Depth Tolerance	Determines the maximum depth deviation value of corresponding segments of different holes which defines them as the same type of hole. This means that if the depth of corresponding segments of different holes are not the same (within the hole depth tolerance), they are not defined as the same type of hole. Example: Example:
Concentric Tolerance	Determines the maximum distance between the center points of segments within a hole which defines them as part of the same hole. This means that if two faces of the same hole do not have the same center points (within the concentric tolerance), they are not defined as being part of the same hole. ExampleExample
Simplify Tolerance	Determines the threshold (equal to or below) which a cylinder on a surface is regarded as a hole. This tolerance value will define as a hole, those surfaces that almost define a cylinder. If the difference between the cylinder and the surfaces is equal to or smaller than the tolerance value, a hole is recognized there.
Maximum Hole Diameter	The maximum diameter the analysis considers to be a permitted hole. A face with a diameter above this value will not be considered as a hole.
Maximum Intersection Length	If the distance between two separate holes with the same axis and the same diameter is within this value, they are considered to be the same hole with an intersection segment. ExampleExample
Minimum Drill Side Clearance	The minimum clearance required from the hole drill point so that the drill tool can enter and actually drill. When deciding if a drill side is to be used, the clearance above the drill side along the tool axis is calculated. This value is the threshold above which the drill side is available. If a Hole exists with no such clearance, it cannot be drilled and it is rejected by the analysis. Example: Example: In an enclosed environment, this value determines whether the drilling can be performed from the inside or from the outside.In an enclosed environment, this value determines whether the drilling can be performed from the inside or from the outside. For example in this picture, the diameter is greater than the Minimum Drill Side Clearance and therefore the drilling can be performed from the inside.For example in this picture, the diameter is greater than the Minimum Drill Side Clearance and therefore the drilling can be performed from the inside.
Recognize holes smaller than 180 degrees	Select this checkbox to enable the system to recognize holes with a circumference of less than 180 degrees. For example, if a hole is drilled on one of the edges of a cube, half of the hole (or 180 degrees of it) is inside the cube and the other half - outside (in void), but it is still recognized as a hole. However, if the circumference of the hole inside the cube was less than 180 degrees and this parameter is not checked, this entity would not be recognized as a hole.
