U.S. Base Plate (1047): Hole size in plate washer

Question: In component US Base Plate (1047), how can different hole sizes be created in the base plate and the cover washer per the image below? I have 1 3/8 dia anchor rods and would like 1 7/8 dia holes in the base plate and 1 7/16 holes in the plate washer.

Answer: In the Anchor rods tab, go to the Create hole in washer section at the bottom of the window. Once you are there, change the option to Yes and type in the size of the hole diameter, as is shown in the image below:


  • To achieve 1 7/8 dia holes in the base plate, set a 1 3/8 bolt size and 1/2 tolerance in the Bolts tab.

  • To have 1 7/16 holes in the plate washer, go to the Anchor rods tab and change the size of the Rod profile to match the Bolt size. Then, set the plate washer's diameter to 1/16.

Here, the diameter of the plate washer acts as tolerance to the rod profile's size:
