If you have a DWT that has all the layers, linetypes, blocks, scales etc already in it and you want Stringer Topo to work inside this DWT, you can run the Import Stringer Imperial Point Styles or the Import Stringer Metric Point Styles. This will bring in all the blocks and Point Styles that are required to get Stringer Topo working in your original DWT or DWG.
Then it will be easier for you to set the right layers for each code in Stringer Settings and have the points use the right Attributed blocks when trying to run a survey through Stringer Topo.
Have a look at this and see how you go.
Good for clients using an Imperial setting.
