Help - SSI

Check out http://geometrygym.blogspot.com for the SSI blog with entries containing tutorials and examples (with sample files to download and try yourself).

Commands and buttons for the set of SSI plug-ins relating to Oasys GSA, Robot, SAP2000, SDNF (Steel Detailing Neutral File), SpaceGass, Sofistik and Strand7 (Strauss7)

Help for SSI

Toolbars Commands

ssiInterpretGWA, ssiInterpretRobot, ssiInterpretSAP, ssiInterpretSDNF, ssiInterpretSpaceGass, ssiInterpretSofistik,ssiInterpretSTRAND7
buttonInterpret.jpg

Left Click prompts user for Structural model data in text file format. You can also interpret data from Windows clipboard contents by right mouse button click.

ssiGSADeleteModel, ssiRobotDeleteModel, ssiSAPDeleteModel, ssiSDNFDeleteModel, ssiSGDeleteModel, ssiSOFDeleteModel, ssiSTRAND7DeleteModel

Delete Rhino model objects generated and identified by SSI plug-in (Objects are tagged with SSI keywords in User Strings).

ssiGSAExportPoints, ssiRobotExportPoints, ssiSAPExportPoints, ssiSDNFExportPoints, ssiSGExportPoints, ssiSOFExportPoints, ssiSTRAND7ExportPoints

Any Structural nodes in the model that are visible will be copied to the clipboard in text data format, allowing you to paste into a text document or the GSA gateway to update/generate a model. Any nodes "hidden" in Rhino willl be ignored.

Sample files and worked examples of using this command can be found here : http://geometrygym.blogspot.com.

ssiGSAGetStructText, ssiRobotGetStructText, ssiSAPGetStructText, ssiSDNFGetStructText, ssiSGGetStructText, ssiSOFGetStructText, ssiSTRAND7GetStructText

Extract structural model data in text file format from Rhino model.

ssiGSAListDialog (Note other model list implementation in progress)
buttonList.jpg

Applies GSA list to model data, either as a selection or by hiding objects.

ssiGSAGetSelectSummary, ssiRobotGetSelectSummary, ssiSAPGetSelectSummary, ssiSDNFGetSelectSummary, ssiSGGetSelectSummary, ssiSOFGetSelectSummary, ssiSTRAND7GetSelectSummary

Get Structural summary of object selection

ssiGSASelectString (Note other model implementation in progress)

Select direct line of elements forming straightest string line

ssiGSAGenStructure, ssiRobotGenStructure, ssiSAPGenStructure, ssiSDNFGenStructure, ssiSGGenStructure, ssiSOFGenStructure, ssiSTRAND7GenStructure

Generate structure from primitive rhino curves and points

ssiGSALabelNodes, ssiRobotLabelNodes, ssiSAPLabelNodes, ssiSDNFLabelNodes, ssiSGLabelNodes, ssiSOFLabelNodes, ssiSTRAND7LabelNodes

Draw node numbers on Rhino Screen Conduit

ssiGSALabelElems, ssiRobotLabelNElems, ssiSAPLabelElems, ssiSDNFLabelElems, ssiSGLabelElems, ssiSOFLabelElems, ssiSTRAND7LabelElems

Draw element numbers on Rhino Screen Conduit

ssiGSAContourConnectivity, ssiRobotContourConnectivity, ssiSAPContourConnectivity, ssiSDNFContourConnectivity, ssiSGContourConnectivity, ssiSOFContourConnectivity, ssiSTRAND7ContourConnectivity

Draw on Rhino Screen Conduit the number of elements connected to each node.

Available Options for SSI interpretation.

Refer to the examples on this web page for demonstration of these interpretation flags.

Section Property Interpretation Flags.

http://geometrygym.blogspot.com/2009/08/interpreting-structural-models-with.html contains a tutorial on these settings

Duplicate Member (-rhD w#,#,#)

Will make a copy of the element, the vector describes the positive and negative offset for the duplicates. Offset relative to local coordinates available soon.

Extend 1st End of Member (-rhE1 #.##)

Extends element at end 1, numerical length of extension specified.

Extend 2nd End of Member (-rhE2 #.##)

Extends element at end 2, numerical length of extension specified.

Loft Sections (-rhL)

Also used for Tapering Members, adjacent elements must be same orientation with sequential property ID

Mitre 1st End of Member (-rhM1)

Member end is defined by bisection plane with adjacent element instead of square to element axis. Adjacent element must be numbered sequentially with defining element but may have different property and orientation.

//Planned, Mitre to global Plane (ie XY, YZ) and possibly arbitrary plane //

Mitre 2nd End of Member (-rhM2)

Member end is defined by bisection plane with adjacent element instead of square to element axis. Adjacent element must be numbered sequentially with defining element but may have different property and orientation.

Relocate Member (-rhR w#,#,#)

Not yet available, coming soon.

Shrink 1st End of Member (-rhS1 #.##)

Shrinks element at end 1, numerical length of reduction specified.

Shrink 2nd End of Member (-rhS2 #.##)

Shrinks element at end 2, numerical length of reduction specified.

Unconnected Member from Element (-rhU #.##)

Interpreter will not connect element to adjacent elements that have same property and orientation (useful for unwanted mitre connections)

List Interpretation Flags

Group Member Layers (-rhG)

Groups generated layers into a parent layer with name derived from list name. List must comprise elements by property (with no to/step intervals for time being)
