Prismaticdialog

Opens when either:

Prismatic is clicked on the Properties - Whole Structure dialog, or
the Prismatic tool is selected in the Beam Profiles group on the Specification ribbon tab

Note: The Properties - Whole Structure dialog also opens simultaneously so that some of the other options available from that dialog may be utilized.

Circle tab

Setting	Description
YD	Section diameter.
Material	Check this box and select the material from the drop down list if the new member property tag should include the material constants.

Setting	Description
YD	Depth of the member in local y direction (local z direction with Z up).
ZD	Width of the member in the local z direction (local y direction with Z up).

Setting	Description
YD	Depth of the member in local y direction (local z direction with Z up).
ZD	Width of the flange, parallel to the local z-axis (local y-axis with Z up).
YB	Depth of the stem (web), parallel to the local y-axis (local b-axis with Z up).
ZB	Width of the stem (web), parallel to the local z-axis (local y-axis with Z up).

Setting	Description
YD	Depth of the member in local y direction (local z direction with Z up).
ZD	Top width, parallel to the local y-axis (local b-axis with Z up).
ZB	Bottom width, parallel to the local z-axis (local y-axis with Z up).

Setting	Description
AX	Cross sectional area of the member.
AY	Effective shear area in local y-axis (local z-axis with Z up).
AZ	Effective shear area in local z-axis (local y-axis with Z up).
IX	Torsional constant.
IY	Moment of inertia about local y-axis (local z-axis with Z up).
IZ	Moment of inertia about local z-axis (usually major, local y-axis with Z up).
YD	Depth of the member in local y direction (local z-axis with Z up). Used as the diameter of section for circular members.
ZD	Depth of the member in local z direction (local y-axis with Z up). If ZD is not provided and YD is provided, the section will be assumed to be circular.
YB	Depth of stem for T-section parallel to the local y-axis (local z-axis with Z up).
ZB	Width of stem for Tee section or bottom width for trapezoidal section parallel to the local z-axis (local y-axis with Z up).

Setting	Description
F1	Depth of section at start node.
F2	Thickness of web.
F3	Depth of section at end node. Note: F3 should be less than F1 (i.e., the section should decrease in depth from start to end). You must provide the member incidences accordingly.
F4	Width of top flange.
F5	Thickness of top flange.
F6	Width of bottom flange. Defaults to F4 is zero.
F7	Thickness of bottom flange. Defaults to F5 if zero.

Setting	Description
Type of Section	Select one of the profile shapes: Round Hexdecagonal – 16-sided Dodecagonal – 12-sided Octagonal – 8-sided Hexagonal – 6-sided Square – 4-sided
d1	Depth of section at start of member.
d2	Depth of section at end of member.
th	Thickness of section (constant throughout the member length).

Notes:

Section properties are calculated using the rules applicable for thin-walled sections.
Shear deformation is not considered for tapered I-Beams and tapered poles. This means that the SET SHEAR command has no effect on the deformation computed for members with these cross sections.

Used to instruct the program to select a suitable steel section based on a profile classification, such as beam, column, double-angle, etc.

Setting	Description
Select Profile Specification	Specify a profile by selecting one of the options: Angle Double Angle Beam Column Channel The program will then assign a section based on that profile from the relevant built-in Steel table.
