Specifications

Specifications and Required Results
Standard Specification
Clash and Contact

By default, this option is selected.

Clearance
Computes clearance during simulation.
Clearance Value
Specify the minimum clearance value. This value is only available when Clearance is selected.
Engineering Connection Specification

See Assembly Design User's Guide for information on creating an engineering connection specification.

Activate

By selecting this check box, the specifications for simulating the interference are taken from the Engineering Connection interference check options.

Check No Clash
An interference result is generated only if the clashes are identified.
Check Contact
An interference result is generated only if the contact is identified.
Check Clearance
An interference result is generated only if the clearance between two components is less that the specified minimum clearance.
No Check
No interference result is generated.
Compute Quantifier
Minimum Distance

Computes and store the clearance minimal distance. This value appears in the interference simulation result, in the Quantifier column.

Note: This option reduces the simulation speed.

This option is available when Engineering Connection Specification is activated.
Penetration Vector

Computes penetration vector and value during simulation.

Note: You can search an interference simulation using advanced search by specifying the penetration value as search attribute.

By default, the option is not selected.

Context

The options for the interference context are as follows:

Inside Groups
You can use Inside Groups to define the interference simulation between the parts or products belonging to one group. You can select one or more groups. However, the computation is done within the objects of the same group.

When you apply engineering connection specifications, the interference is detected between the parts of the individual group.

Groups Against Groups
You can use Group Against Groups to define the interference simulation between the parts or products belonging to several different groups. The computation is done between combination of groups. All parts of one group are checked against all parts of other groups.

For example, if we have three groups: Group1, Group2, and Group3 the system will check:

  • All parts of Group1 against all parts of Group2
  • All parts of Group1 against all parts of Group3
  • All parts of Group2 against all parts of Group3
Note: Combination between the parts belonging to the same group is not checked to avoid unwanted computation and interference generation.

You can select one or more products within each group.

When you apply engineering connection specifications, the interference is detected between the parts of the different groups.

Group1 against Context
You can use Group1 against context option to define the interference simulation between the selected object (parts or products), against the remaining objects (parts and products) in the assembly context. You can select one or more products within a selected group. When this option is selected, you do not have to select a second group.

When you apply engineering connection specifications, the interference is detected between the parts of the group1 and parts belonging to rest of the context.

Defining Groups
Add new group
This option allows you to create one group at a time. Using this option, if you select the Product or Parts node in the graphic area or the tree, all the child objects are automatically added to a new group.
Add more groups
The option allows you to create multiple groups, in one selection, by selecting the product or part nodes. Each product selected is added as a separate group in the context.
Delete all groups
This option allows you to delete all the groups in the context.
Group Operators
Allows you to add more objects to the selected group.
Allows you to remove objects from the selected group.
Allows you to delete the selected group.
Highlights the selected group in the graphic area.
