In This Topic

Checks whether two 3d objects collides each other.

Syntax

C#
C++/CLI

public bool CheckIfPlacementsCollide( 
   Placement3D pPlacementA,
   Placement3D pPlacementB,
   bool bConsiderMountingClearance,
   bool bExcludeAllowedCollisions
)

public:
bool CheckIfPlacementsCollide( 
   Placement3D^ pPlacementA,
   Placement3D^ pPlacementB,
   bool bConsiderMountingClearance,
   bool bExcludeAllowedCollisions
)

Parameters

Parameter Name	Description
pPlacementA	First of 3d placements used to check collision. Can't be `null`.
pPlacementB	Second of 3d placements used to check collision. Can't be `null`.
bConsiderMountingClearance	Use mounting clearances for checking collisions.
bExcludeAllowedCollisions	If true, collisions which are allowed are not reported.

Return Value

Returns true if a collision between two objects is found.

Exceptions

Exception	Description
System.ArgumentNullException	Thrown when necessary argument is `null`.
System.ArgumentException	Thrown in case of invalid arguments.
System.ApplicationException	The functionality is not available.

Remarks

Method checks whether two objects collides each other. This is done by checking if bounding boxes of these objects don't share common space and if they do then the check is done using their meshes.

In some cases collisions between two objects are allowed. This happens due to inaccuracy of some meshes and is acceptable for example in case of a terminal on a rail. Parameter bExcludeAllowedCollisions helps to control whether such collisions should be reported or not.

Many objects in layout space represents only logical instances without meshes. For example Cabinet or Plane are one of such objects. In this case, collision with these objects will not be reported.
