  27. Converting an Arc to a Beam • Select the Beam tool of the Design tool palette, right-click, and choose Apply Tool Properties to>Linework.) • Select lines, arcs, or open polylines to convert into members: 1 found (Select the arc at p1 as shown above.) • Select lines, arcs, or open polylines to convert into members: ENTER (Press ENTER to end the selection.) • (TheConvert to Beamdialog box opens; respond to theErase Layout Geometrycheckbox. ClickOKto dismiss the Convert to Beam dialog box.) • (Edit the Properties palette to assign the structural style.)

  28. Converting Linework to Structural Members • The Structural Column, Structural Beam, and Structural Brace tools located on the Design tool palette each include a shortcut menu option to convert linework to the structural member. • Therefore you can draw an arc, line, or polyline and convert the geometry to a structural member. The linework becomes the axis line for the structural member.

  29. Accessing the Style Wizard • Command prompt: MEMBERSTYLEWIZARD • Select Manage tab. Choose Structural Member Wizard from the Style & Display slide-out menu.

  35. Accessing Structural Grids • Command prompt: COLUMNGRIDADD • Select Column Grid from the Build panel or the Design tool palette. • Column grids are developed to uniformly place structural columns in the plan view. • The grid can be rectangular or radial in shape.

  36. Basic-General Description Shape Boundary Dimensions X-Width Y-Depth X AXIS Layout type Number of Bays Bay Size Start offset End offset Y AXIS Layout type Number of Bays Bay size Start offset End offset Column Style Dimensions Start offset End offset Logical length Justify Justify cross-section Justify components Location Rotation Elevation Additional Information Advanced Trim Planes Structural Column Grid Properties

  37. Rectangular Layout Types • Manual–The Manual option is only available for editing existing column grids. The Manual option creates a Bays button in the Properties palette. The Bays button opens a Bays along the X Axis dialog box which list the distance to line for each bay of the grid. • Space Evenly–The Space evenly expands the X-Axis allowing you to specify the Number of bays, Bay size, Start offset, and End offset. • Repeat–The Repeat option allows you to specify the bay distance.

  40. Accessing the LayoutGridClip Command • Command prompt: LAYOUTGRIDCLIP • Select a column grid choose Set Boundary from the Clipping pane of the Column Grid tab. • The clip is defined by a closed polyline. • Clipping a column grid allows you to only see that part of the grid, which is inside the closed polyline. • The clip can be applied when the grid is inserted or added to an existing grid.

  41. Placing Hole in a Column Grid • (Select a column grid, choose Add Hole from the Clipping panel of the Column Grid contextual tab.) • Select layout grids: 1 found (Select the column grid at p1 shown below.) • Select layout grids: ~EnterKey~(Press the ~EnterKey~ to end the below.) • Select a closed polyline for hole: (Select the polyline at p2 as shown below.) • (Press the ~EscKey~ to end the command and view the column grid as shown below at right.)

  42. Defining the Column for the Grid • Columns can be inserted at each intersection of the column grid by selecting a style from the Style drop-down list in the Properties palette as shown at right. • The content of the drop-down list includes the structural member styles created from the Structural Member Catalog and used in the drawing. • The column style will be inserted at each intersection of the column grid, however you can erase selected columns from the grid. • The properties such as logical length, start offset, end offset, justify, and justify using overall extents are set in the Dimensions section of the Properties palette of the column grid. • Columns inserted in the column grid can be edited independent of the remaining columns by selecting the column and changing their style or other properties in the Properties palette.

  43. Grips of the Rectangular Column Grid

  44. Adding and Removing Column Grid Lines • The Column Grid tab allows X Axis and Y Axis edits: • Add Grid Line • Remove Grid Line • Layout Mode • Choosing the Layout Mode allows you to change the grid as follows: • Manual • Repeat • Space Evenly

  45. Steps to Adding a Grid Line • (Select the column grid with Manual layout type, as shown below; and choose Add Grid Line from the X Axis panel.) • Enter X length <10’-0”>: 15’ enter (Column grid line added 15’ from the insertion point along the x axis as shown at right below.)

  46. Labeling the Column Grid • Command prompt: COLUMNGRIDLABEL • Select a column grid and choose Label from the Label panel of the Column Grid tab.
