Structural, Parts

Contains controls that define the physical characteristics of a structural member upon placement. Settings include default section, placement point and local offsets.



This Structural View menu item dialog is accessed by choosing Properties from the right-click pop-up menu in the list box, while the Parts View on Family/Part Editor is Structural.

SettingDescription
Section Name Displays the default structural section used by the part being defined.

Key in the section name or click the Select button to browse in the Structural Sections dialog.

Select Opens the Structural Sections dialog, listing industry standard section sizes. You may shorten the list using the Code and Type filters, and select a structural member's section from the listed section sizes. The selected section displays in the Section field.
Tip: The Structural Sections dialog also opens by clicking on the entry in the Section column on the list box in the Family/Part Editor.
Show Fillet When on, fillets between member flanges and web are fully modeled and displayed.
Rotation Defines a default angle of rotation about the member centroid upon placement.
Mirror Indicates mirroring. When on, flips the flanges to the opposite direction.

Applicable to members, such as angles, channels, or zees whose axis is asymmetrical about its Y axis.

Placement Point Defines the location on the section to be used as the origin of the member upon placement. There are nine physical placement points and one theoretical centroid available.

To alter the structural member's Placement Point, click on the icon to select one from the pop-up options:

  • Bottom Left – to the lower left flange's corner.
  • Bottom Center – to the lower flange's center outside edge.
  • Bottom Right – to the lower right flange corner.
  • Center Left – to an area equidistant between the outside left flanges.
  • Center Center – to the center of the beam.
  • Center Right – to an area equidistant between the outside right flanges.
  • Top Left – to the top left flange's outside corner.
  • Top Center – to the top center flange edge.
  • Top Right – to the upper right flange corner.
  • Centroid – Sets the structural member's placement point to the centroid.
The spot represents the placement point on the section that is placed at grid points 0,0 of the X/Y axis.
Place by Sets the default placement method for a single member placement such as a column or beam.
  • Two Points – Sets placing the member by entering two data points.
  • Length – Sets placing the member constrained to the length specified in the Length field next to Place by. In placement tools it is controlled by the position of the AccuDraw compass.
  • Select Path – Sets placing the member along the path of a primitive element.

    The primitive elements which can be used in the placement are:

    • lines
    • line strings
    • shapes
    • curves (including B-spline curves) – lets you place a curved member
    • complex strings
    • complex shapes
    • arcs – lets you place a curved member
Local Y/Z offset Sets the offset values that determine member placement dynamics and member positioning relative to local coordinates. It moves the physical member's placement away from the member line in the Y-/Z-axis direction.
OK Accepts changes and dismisses the dialog.
Cancel Discards changes and dismisses the dialog.
Apply Applies changes without dismissing the dialog.
