Direct modeling commands

BricsCAD® direct modeling commands can create both solid and surface geometry. To distinguish direct modeling commands from other commands, all direct modeling commands have a prefix DM.

Direct modeling commands are available in Pro, BIM, Mechanical and Ultimate license levels. Commands that create geometry are also available in BricsCAD® Shape, along with basic modification commands such as DMPUSHPULL, DMCHAMFER and DMFILLET.

Creation commands

EXTRUDE: creates 3D solids or surfaces by extruding open or closed 2D entities, faces of 3D solids, regions or closed boundaries. Optionally adds volume to solids or removes volume from solids.

REVOLVE: creates 3D solids or surfaces by revolution of open or closed 2D entities or regions about an axis.

DMTHICKEN: creates 3D solids by thickening (i.e. adding thickness to) surfaces, their faces, faces of 3D solids, regions and wire entities.

DMCOPYFACES: copies a set of 3D solid faces forming a feature (e.g. hole, rib or protrusion) to a new position on the same or another 3D solid.

DMSTITCH: converts a set of region and surface entities that bound a watertight area to a 3d solid.

Modification commands

DMCHAMFER: creates equal distance and variable chamfers between adjacent faces sharing a sharp edge.

DMDEFORMCURVE: deforms one or more connected faces of a 3D solid/surface by replacing their edges with given curves.

DMDEFORMMOVE: deforms one or more connected faces of a 3D solid/surface by moving and rotating their edges.

DMDEFORMPOINT: deforms a region, one or more connected faces of a 3D solid or a surface by moving a point lying on one of them in arbitrary 3D direction. The selected faces are deformed as smooth as possible.

DMFILLET: creates a smooth fillet between adjacent faces sharing a sharp edge.

DMPUSHPULL: adds or removes volume from a solid by moving/offsetting a face.

DMROTATE: rotates solids, faces, edges, or vertices of a solid around an axis.

DMTWIST: modifies a 3D solid, surface or region by twisting a portion defined by two points around an axis.

Helper commands:

DMAUDIT: fixes inconsistencies in 3d geometry supported by ACIS kernel (3D solids, surfaces).

DMAUDITALL: fixes inconsistencies in 3d geometry supported by ACIS kernel (3D solids, surfaces) in drawings inserted as external references.

DMGROUP: creates group features, which are named persistent collections of faces and edges of 3D solids and surfaces.

DMSELECT: selects edges and faces of 3D solids or surfaces based on their geometric properties.

DMSELECTEDGES: selects the edges of faces and solids.

DMSIMPLIFY: simplifies the geometry and topology of 3d solid entities. The command removes unnecessary edges and vertices, merges seam edges, and replaces the geometry of faces and edges by analytic surfaces and curves, if possible within the user-specified tolerance.

The direct modeling commands are available in:

  • The Model tab on the Quad cursor menu when the cursor is over an entity or subentity or when a selection set exists.
  • The Direct Modeling menu.
  • The Direct Modeling, Fillet, Chamfer and Deform toolbars.
  • The Home / Direct Modeling ribbon panel (Modeling workspace).
Icon Command Applies to
DMPUSHPULL command Any face of a 3D solid or surface.
DMMOVE команда Cylindrical, spherical, conical, and toroidal faces of a 3D solid or surface.

Linear and circular edges of a 3D solid or surface.

Whole 3D solids, surfaces, and other entities.

DMROTATE команда Planar, cylindrical, spherical, conical, and toroidal faces of a 3D solid or surface.

Whole 3D solids, surfaces, and other entities.

DMSIMPLIFY команда 3D solids, surfaces, and their faces.
DMSTITCH command Surfaces.
DMAUDIT command 3D solids and surfaces.
UCS command Planar faces of 3D solids and surfaces.

This tool launches the UCS command with the Face option selected.

Note: When the Dynamic UCS feature is ON, the UCS aligns automatically to the solid face under the cursor and the UCS-icon changes accordingly.
EXTRUDE command

Solid mode

Closed 2D entities and detected closed boundaries.

If the Select detected boundaries option of the SELECTIONMODES system variable is switched ON, boundaries enclosed by 2D linear entities in the XY-plane of the current UCS are detected automatically.

Planar faces of 3D solids and surfaces.

Closed 2D entities and detected closed boundaries on a planar face of a solid.

REVOLVE command

Solid mode

Closed 2D entities and detected closed boundaries.*

Planar faces of solids and surfaces.

Closed 2D entities and detected closed boundaries on the planar face of a solid.

XFACES command

Extract Faces

Surfaces and faces of 3D solids.
DMCOPYFACES command A set of 3D solid faces.
DMTHICKEN команда Faces of 3D solids and surfaces.

Surfaces.

Wire entities; lines, polylines, circles, ellipses, arcs, helices, and splines.

DMFILLET command

Constant radius mode

Sharp edges of a 3D solid or surface.
DMFILLET command

Variable radius mode

Sharp edges of a 3D solid or surface.
DMCHAMFER command Sharp edges of a 3D solid or surface.
DMCHAMFER command

Advanced Mode

Sharp edges of a 3D solid or surface.
ERASE команда Faces of a solid or a surface.

Whole 3D solids and surfaces.

Free edges of a surface (a surface edge is called free if it has only one adjacent face).

Edges between coplanar faces.

EXTRUDE command

Surface mode

2D linear entities and edges of 3D solids and surfaces.
REVOLVE command

Surface mode

2D linear entities and edges of 3D solids and surfaces.


DMDEFORMPOINT command Faces of a 3D solid or a surface.


DMDEFORMMOVE command Edges of a 3D solid or a surface.


DMDEFORMCURVE команда Edges of a 3D solid or a surface.
