Interfere

Shows volumes and areas of interference between two sets of ACIS entities.

The Platinum edition additionally shows volumes of interference between two sets of ACIS solids, and then optionally creates new ACIS solids from the common portions of pairs of intersecting solids, placing them on layer "Interferences."

 

Accessing the Command

command bar: interfere
transparent: 'interfere
alias: inf
menu bar: Model | 3D Solids| Interfere
toolbar: 3D Solids |

: interfere

Prompts you in the command bar:

Select first set of Acis objects or [Nested selection/Settings] <Nested selection>: (Choose one or more 3D solids or 2D regions to make up the first set, or else type N or S)

Entities in set: 1

Select first set of Acis objects or [Nested selection/Settings] <Nested selection>: (Choose more ACIS entities, or else press Enter to continue)

Select second set of entities or [Nested selection/Settings/checK first set] <checK first set>: (Choose one or more 3D solids or 2D regions to form the second set, or choose an option)

Entities in set: 1

Select second set of entities or [Nested selection/Settings/checK first set] <checK first set>: (Choose more ACIS entities, or else press Enter to continue)

Comparing 1 solid against 1 solid.

Interfering solids (first set): 1

(second set): 1

Interfering pairs: 1

Created 1 interference solid on layer Interferences

The interference solid remains in the drawing when the command ends.

 

Command Options

Option

Description

Select first set of Acis objects

Specifies the first set of ACIS entities: choose one or more 3D solids and/or 2D regions.

You can respond with all to place all ACIS entities into a set, and then later use the checK first set option to check them against each other; this obviates the need to create two sets of entities.

Nested selection

Selects ACIS entities inside blocks or xrefs; prompts you:

  1. Select nested Acis objects for first set [eXit] <eXit> - (select a nested ACIS entity.)
    Entities in set: 1

  2. Select nested Acis objects for first set [eXit] <eXit> - (select more nested ACIS entities, or else press Enter to proceed.)

 Settings

Displays a dialog box:

  • Create interference solids - when on, makes new solids from the interference area or volume
  • Layer - specifies the layer on which to place the new interference entities
  • Color - specifies the color of the interference entities; the color of the layer is changed to match is color
  • OK - exit the dialog box and returns to the command

Select second set of Acis objects

Specifies the second set of ACIS entities: choose one or more 3D solids and/or 2D regions.

The entities in the first set are compared with the entities in the second set.

checK first set

 Checks the interference of entities in the first set, when it contains two or more entities, and then creates interference enty(ies) of them.
