Form: Wall Shell Object Curve Type Options
Use the Edit menu > Edit Shells > Modify/Show Wall Curve Type command to review or modify the shape of selected wall type shell objects.
Note: This command works only with shell objects that were drawn as walls and if only one wall object is selected.
Select a wall object or edge and use the Edit menu > Edit Shells > Modify/Show Wall Curve Type command to access the Wall Shell Object Curve Type Options form.
Shell Object Information:
Story; Label: The story/label of the wall object selected is listed.
Line Type: Select Straight, Circular Curve, Multilinear Curve, Bezier Curve, or Spline Curve from the drop-down list for the line type as viewed in plan. The selection here will affect which items are displayed in the Curve Definition area.
Start Joint Object (Bottom of Wall): The coordinates and name of the starting joint for the line are listed.
End Joint Object (Bottom of Wall): The coordinates and name of the ending point for the line are listed.
{Straight Line Data, Curve Definition}: Enter additional geometric parameters to define the line curves selected in the Line Type drop-down list in the Shell Object Information area.
If the line type is Straight, no additional information is required.
If the line type is Circular Curve, specify either the Radius or the coordinates of the Third Point on Curve. When using the radius option, ”Line” refers to the imaginary straight line defined by the start and end joints of the edge.
If the line type is Multilinear Curve, enter the number of internal points (IP) needed to define the line in the edit box and then the coordinates of each IP in the spreadsheet cells.
If the line type is Bezier Curve, enter the number of internal control points (ICP) needed to define the line in the edit box and then the coordinates of each ICP in the spreadsheet cells.
If the line type is Spline Curve, enter the number of internal control points (ICP) and the spline curve tension needed to define the line into the edit boxes, and then the coordinates of each ICP in the spreadsheet cells. The higher the spline curve tension, the more taut the curve will be through the control points; this value should not exceed 1.
Area Edge Midpoint Coordinates display boxes. These display boxes identify the location of the X and Y coordinates of the midpoint of the area edge relative to the global coordinate system.
Refresh Window: The Refresh Window button updates the display with any changes made to the wall geometry without leaving the Wall Shell Object Curve Type Options form.
