h1. 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.


h1. 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.

h1. 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


h2. Model "RoundSolids.dwg"

!Figure 01.png|hspace=30px,width=800px!

!Figure 02.png|hspace=30px,width=800px!

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


h2. Model "RoundSolids2.dwg"

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


h2. Model "SolidImporttest.dwg"
