Creating a Partially Threaded Rod

There are times that you may need to create a partially threaded rod, such as you get for an anchor bolt. The system components will create them with clearly defined threaded areas that you can see and dimension to on the drawings.

You cannot create a similar rod with a single command, since there are no profiles that allow you to define that certain portions of them are differently sized.

First model in the section of rod that will not be threaded. This will be the main piece.

Next model in the section(s) that will be threaded – use a rod diameter that is slightly smaller.



Currently these are three separate pieces and if we attached them to one another in the traditional fashion, using welds or Add to Assembly, they would still be billed out as three distinct parts.

Instead we will use the Attach to Part command. Go to Detailing > Added material > Attach to Part.

First select the main section of rod, and then the threaded end(s). Finish with a middle mouse click.

This will add the threaded section(s) to the main rod, so if you hover over the main part the entire thing now highlights as a single part.



If you create a drawing of the part it displays the entire length in the BOM and the threaded sections can be dimensioned.



To complete the assembly you can model in nuts and washers with the beam tool (profiles are found under ‘other’ in the catalog) and weld them in place.
