SAP2000 DWG Export

SAP2000 support export of DWG objects as described in the table below:

	SAP2000 Object	DWG Entity
1	Point	AcadPoint
2	Line	AcadLine
3	NLink (2 or 3 Points)	AcadLine
4	NLink (1 Point)	AcadPoint
5	Area	Acad3DFace
6	Solid	AcadPolyFaceMesh

Note: If you try to export DWG file without AutoCAD installation then you get a warning message. It is normal. In SAP2000, we use ActiveX late binding and try to create AutoCAD objects. If we are not able to create them then its mean AutoCAD is not installed. But this is only done for AutoCAD DWG import/export, import from DXF and export to DXF does not require AutoCAD to be installed.

SAP2000 DWG Import

SAP2000 support import of DWG objects as described in the table below:

	DWG Entity	SAP2000 Objects
1	AcadPoint	Point
2	AcadLine	Line/NLink
3	Acad3DFace	Area
4	AcadDb3DSolid	Solid

Notes:

DWG Solid objects is different in import and export. AcadDb3DSolid easy to build in dwg file (good for import). AcadPolyMesh is good to know the coordinates (good for export).
DWG Solid import was available in SAP2000 V11.0.4, but not it is not currently available in SAP2000 V12 and V14.

Sample DWG files for Import

SAP2000 supports following AutoCAD2007 entities for solid import:

Box
Wedge
Pyramid (or frustum)
Extrusion of 3DFace - possible for all "3DFace" entities making a legal shell (four nodes)

Following three files have been used for the testing of above mentioned entities

RoundSolids.dwg
RoundSolids2.dwg
SolidImporttest.dwg

Model "RoundSolids.dwg"

AutoCAD "3DFace" entities were converted to Solid by using command "Extrude". After performing ‘Rotate3D’ operation all solid entities were imported into SAP2000.

Model "RoundSolids2.dwg"

AutoCAD "3DFace" entities were converted to Solid by using command "Extrude".

Model "SolidImporttest.dwg"

Import of AutoCAD "3dSolid" entities (box, wedge and pyramid) in to SAP2000.
