Creating an Irregular Dispatch
To create an Irregular Dispatch rebar cage:
Distributes rebar
along / between Variable Length Guidelines and associates them with a Concrete
Element.
- Select (Irregular Dispatch). On your model, click to select a Concrete Object to add rebar. The Irregular Dispatch dialog opens.
- Select your Bar Size from the drop down list.
-
Select your
Dispatch Method from the drop down list.
- Vertex - Places Rebar between all Vertices of the Line / Smartline Connects all vertices (Distribution Values are ignored with this Method & all lines / smartlines must have same # of Vertices and/or Segments).
- Spacing - Places Bars at the Start and End of the Line / Smartline / Arc or Spline (Offset values will shift Start and End bars based on values entered) ignoring vertices then distributes bars equally across remaining distance using indicated spacing (Not to exceed).
- Combination (All Lines / Smartlines must have same # of Vertices and/or segments) combines Vertex & Spacing Methods spacing the bars at the Start & End of each segment (Offsets apply to each segment) then distributes bars equally across remaining distance using indicated spacing (Not to exceed).
- Enter Start Offset / Spacing / End Offset Distribution values if using the Spacing or Combination Methods (a spacing greater than 0 is required in these methods).
- Click (Select / Add Guidelines).
- Right Click or press <Enter> to return to the Irregular Dispatch dialog.
-
Selected Guidelines will be displayed in the Guideline Grid on the
left side of the dialog.
To Modify or Delete the selection left click to highlight the
guideline, (the Guideline will highlight in your drawing) to be modified then
right click to bring up your modification / deletion options:
- Remove Guideline – Removes current guideline.
- Reverse Guideline – (Reverses the order the points in the Line / Smartline / Arc or Spline were selected).
- Make Arc Intermediate Point – (Only an option when selecting 3 Guidelines) Creates a uniform arc bent bar between the 3 guidelines (3 point arc method).
- Make Normal Vertex – Option only appears after you have made the middle of your 3 Guidelines a Arc Intermediate Point.
- Cancel – Closes the right-click options.
In the Combination Dispatch Method the QTY can be manually adjust by left clicking in the Segment Grid on the segment # that needs adjustment and keying in the desired # of bars. The Numbers shown in parenthesis are the recommended # of bars per segment (Vertex Bars aren't included in totals) base on your spacing and the longest line in the segment.
The tool takes precaution of ensuring the guide lines'
directions are maintained same. If no reversing guide line, no cross bar is
generated. With reversing, the cross bar gets created. The "X" cross mark in
column Reversed indicates that the guideline will definitely generate the cross
bars. To generate the normal bars, toggle off all reversed status.
