When placing ductwork and using the autolayout features (i.e. choose a plus sign on a duct segment to place a branch), takeoffs are automatically centered in the sides of the duct segment. However, if you want to place a takeoff that is offset from the center of the segment, you need to manually place the takeoff fitting first, then continue duct from the fitting.
To place an offset takeoff:
1. Draw the main duct segment first.
2. Use the Add Duct Fitting tool (from the Duct tool palette), and choose the type of takeoff you wish to use.
3. The command prompt will ask you to select an insert point or ductwork – choose the duct at or near the location you want the take off placed.
4. Before choosing the rotation of the fitting, go back to the Add Duct fitting dialogue and choose the Off Center tab.
5. Check Enable off-center placing, change the side to the side of the duct (top/bottom/left/right) where the take off will be placed, then choose the offset distance. Note that for a takeoff on the right or left side of a duct, a positive distance will place the takeoff up towards the top of the duct, while a negative number will place the takeoff towards the bottom of the duct, if the Center justification is set. The distance is measured to the centerline of the take – make sure you don’t try to place the takeoff beyond the size of the duct segment you’re attaching to.
This will place a takeoff at a location other than the centerline of duct. To adjust after placement, right click on the fitting and choose Duct Fitting Modify from the pop-up menu (note – the off center tab is not available for fittings placed during autolayout).
Try this out and let us know how it works!
