: dmpath3d

Prompts you in the command bar:

Select path (any curve-like entity): (Select a polyline, 3D polyline, spline, or helix.)

Select a point/vertex [WOrld/BLock]: (Select a point or choose an option.)

Specify the value of the curve parameter (min 0, max 412) or [Geometry-driven] <174.34>: (Type the desired distance or choose an option.)

Option	Description
WOrld	Allows you to select the WCS subentity as an argument; prompts you in the command bar: Select reference coordinate system subentity [Origin/X axis/Y axis/Z axis/XY plane/YZ plane/ZX plane] - (Select a reference coordinate system subentity as an argument.)
BLock	Allows you to choose, as an argument, the subentity of the coordinate system of the block; prompts you in the command bar: Select block reference - (Select a block reference of which the reference coordinate system will be used as an argument.) Select reference coordinate system subentity [Origin/X axis/Y axis/Z axis/XY plane/YZ plane/ZX plane] - (Select a reference coordinate system subentity as an argument.)
Geometry-driven	Accept the current value and create a geometry-driven constraint.

DmConstraint3D - applies geometric relationships and dimensional constraints between subentities (faces, surfaces, edges, ...) of 3D entities.

DmUpdate - Forces 3D constraints to update.

DmCoincident3d - applies a coincident constraint between two edges, two faces or an edge and the face of two different solids.

DmDistance3d - applies a distance constraint between two subentities of a solid or of different solids.

DmTangent3d - applies a tangent constraint between a face and a curved surface of different solids.
