Autocad/Intellicad and DXF Entity Type Selection

Geometry to Convert

This information applies for setting up geometry data import both for direct import when running within Autocad/Intellicad and when importing data from a DXF file.

3D FACEs
3dfaces will be split to two triangular polygons if not planar.

Extruded and Flat 2D SOLIDs
Solids will appear as a single polygon or as a box if the thickness is not zero.

Extruded and Flat TRACEs
Traces will appear as a single polygon or as a box if the thickness is not zero.

Extruded 2D-PLINEs
2d-polylines with a thickness different from zero will appear as a set of polygons. With R14, this includes lightweight polylines.

Wide 2D-PLINEs
2d-polylines with a starting width different from zero set in their header entity (not the vertexes!) will appear as a polygon following the trace of the polyline with a constant width. This option will override the one below for poly- lines that match both categories. Together with a thickness and the respective option set this will will result in a kind of a quadrilateral worm. With R14, this includes lightweight polylines.

Closed 2d-PLINES as Polygons
2d-polylines with the closed flag set in their header entity will appear as a polygon of the shape of the polyline. polylines with a width will not follow this rule if the option above is chosen as well (Wide 2d-plines). Together with a thickness and the respective option set this will result in a prismatic volume of the shape of the polyline.
This option is off by default.

3D-MESHes
The Faces of 3d-polygon meshes will appear as a set of polygons ignoring spline fits of any kind. Nonplanar faces will be split into two triangles.

POLYFACEs
The faces of polyface meshes will appear as a set of polygons. Nonplanar faces will be split into two triangles.

Extruded LINEs
Lines with a thickness different from zero will appear as a single polygon.

Extruded ARCs
Arcs with a thickness different from zero will be segmented according to the given arc tolerance.

Extruded and Flat CIRCLEs
Circles will appear as a ring with a inner radius of zero or as a cylinder/tube with a ring at either end if their thickness is different from zero.

POINTs as Spheres
Point entities will appear as spheres or bubbles depending on either their thickness (if any) or else on the value of the DXF variable "PDSIZE". if the result is zero the entity is ignored.
This option is off by default.

ACIS 3D Solids
ACIS solids are topologically closed volumes in boundary representation, and will be converted to sets of triangle polygons.
This selection is only available when importing directly from Autocad 2000.

ACIS Bodies
Bodies are partial 3d solids, which may be topologically open.
This selection is only available when importing directly from Autocad 2000.

ACIS 2D Regions
Regions are planar entities that can be manipulated per boolean operations, and will be converted to sets of triangle polygons.
This selection is only available when importing directly from Autocad 2000.
