To Perform an Interference Detection Query

Detecting Interferences > Interference Detection > To Perform an Interference Detection Query

1. Click Tools >

Interference Detection. The Interference Detection Settings dialog box opens.

2. Select a Query Name from the list or type a new name.

If you select a query from the Query Name list that was calculated using the Penetration-based calculation method, you will receive a message about the option of switching to the current Volume-based calculation method. If you do not receive the message, continue to step 4.

3. Close the message to continue, and then select an Interference Calculation Method.

◦ Volume-based tolerance—New queries automatically use this calculation method.

◦ Penetration-based tolerance—Legacy calculation method.

▪ You can still load or recalculate old reports that calculate Tolerable Penetration.

▪ Comparing old reports with new ones may result in inaccurate results.

▪ Penetration-based tolerance will not be supported in future releases.

4. Under Calculation Mode, select Accurate or Approximate.

• To calculate the interference volumes in Approximate mode, Calculate interference volumes when running in approximate mode must be selected in the Interference options.

• Interferences with no calculated volume are treated as interferences, and Unavailable appears in the Volume column.

5. Select an interference Detect option of the following type or combination of types:

◦ Interference

◦ Interference + Contact

Interference + Contact + Clearance

(See Setting Interference Detection Types)

6. Type a value for one or more of the following fields:

◦ Using Volume-based tolerance

▪ Tolerable Volume

▪ Tolerable Distance

▪ Required Clearance

In addition, input items can have their own Clearance value. See To Create Input Lists and Exclusion Lists for details.

◦ Using Penetration-based tolerance

▪ Tolerable Penetration

▪ Tolerance

▪ Required Clearance

7. Create Input and Exclusion lists. (See To Create Input Lists and Exclusion Lists for details.)

8. Perform the following steps to save the query settings:

a. Click Manage Queries. The Manage Queries dialog box opens with the given Query Name inside.

b. Click Save. The Save dialog box opens.

c. Click OK to save the query, or change the name and then click OK. The query name is added to the list in the Manage Queries dialog box.

d. Click Close. The Manage Queries dialog box closes.

9. Click Calculate. The results appear in a list in the

Interference Detection panel and graphically in the Interference View.
