No matter how they are created, all members that are created from standard sections have many common properties available.

Figure 7-8  Section & Material tab

o Section: Select the required section type and size. The first drop-down arrow enables you to select the family of sections (e.g., I, Channel, or Round), the second drop- down arrow selects the section class in the family (e.g.,

IPE, UK Universal Beam, or JIS H) and the third drop-

down arrow enables you to select the size of the beam in the selected section class. The fourth drop-down arrow displays a list of recently selected sections for quicker re- selection.

o Material: Enables you to select the material from which the beam is to be made. The first drop-down is the type of material (e.g., Steel or Concrete) and the second drop- down is the exact material of the selected type (e.g.,

S275JR or St37-2).

o Coating: Select the required coating/finish for the beam (e.g., Iron Oxide Primer or Galvanised).

The list of entries displayed in the short list is controlled by a system called Preferred Sizes. Although outside the scope of this training guide, you can customize them to suit your requirements. Contact your Autodesk representative for more information.

 Positioning tab

Figure 7-9

o Offset: Select how you want the beam to be positioned relative to the selected points. The image of your beam type has 10 positions from which you can select. Nine of these positions represent the four corners, the middle of the four sides, and the center. The tenth dot represents the

Centre of Gravity of the section. Normally vertical

members, such as columns, are placed using the Center position. Horizontal members, such as floor beams, are typically placed using the Top Middle position.

o Angle: Rotates the section about the system line. Select the dot corresponding to 45° increments or enter the required value in the box. When a beam is first placed the

Note: Each of these drop-down lists is filtered to only display

options that are common in your location (depending on the language selected during the installation). If the required option is not displayed in the short list, you can use the All option at the bottom of the list. Selecting it displays the full list of all of the entries that are included in the Autodesk Advance Steel software.

Note: A line is drawn between the two selected points. It is called

the System Line and does not move when you select these position offsets. The beam moves around the line. Always draw the system line between your nominal design points and enable the Autodesk Advance Steel software to determine the detail.

Warning: For non-

symmetrical sections, such as Channels, Angles, and T sections, the positions in the middle of each side line up with the center of gravity and

therefore are often NOT in the middle of that side.

top flange is parallel with the current UCS XY or YZ plane. The angle setting always displays zero when the dialog box is first opened and this corresponds to the current position of the section.

 Naming tab: Displays the Single Part and Assembly numbers of the part plus additional identification, such as lot/phase and

Model Role.

Figure 7-10

o Single Part/Main Part: There are boxes to the left of the

Single Part Number and Main Part Number. If the box

next to single part is checked, it indicates that the part is a single part. If the box next to Main Part is checked, it indicates that the part is the main part of the assembly. o Model Role: To identify what part a specific object plays

in the structure and to assign an appropriate number prefix, the object needs to have a Model Role assigned, such as Beam, Column, Rafter, End Plate, or Railing

Post Landing. This is selected in the drop-down list.

When an object is created by an Advance Steel macro, the appropriate model role is assigned automatically. When you create an object manually, you must manually assign the model role.

If you want to align one beam with another at an

unknown angle (such as having roof beams align with rafters), rather than trying to find the correct angle to enter, set the UCS to match the other beam (UCS at

Object) before

placing this beam. The flanges align automatically.

 Camber Properties tab: If you design a cambered beam you can enter the properties on this tab. The Autodesk® Advance Steel software can then recognize the type of beam so that it is drawn and identified appropriately for manufacture. Only straight beams can be cambered. You might need to manually specify a Cambered Beam drawing style to benefit from this feature.

 Fabrication data tab: Model Objects (beams, plates, gratings, etc.) and Assemblies (groups of elements joined by certain criteria) have different fabrication information available in the model, depending on the project state.

Draw Beams and Sections

1. Draw the remaining members of the structure.

2. Model all of the remaining beams and sections in the structure (except the bracings). Carefully orient and position each beam on the outside platform correctly.
