The insert pole spec tool will automatically match the three birthmark attributes (pole height, pole class, and pole species) to a pole spec for your model. Pole specs will be required before running pole loading analysis (so this tool may only be needed in PLA workflows) but it's convenient to insert the spec now during the data entry phase. It's important to note that for the tool to work properly, the three birthmark attributes need to match the input for the spec exactly. This is pretty easy for the numeric pole height and class, but you will want to ensure the characters for pole species match the characters for pole spec (i.e. "Southern Pine" vs "Southern Yellow Pine" won't be the same thing).
When using this tool, if the pole height, pole class, or pole species attributes were not entered during the classification step, you will see warnings appear to prompt the user to go back and enter that information.
