Use this macro for many things, including labeling cross-sections imported from PDF where the text in the PDF is absent (replaced with polylines that look like text, but are not text). Often PDF files have text drawn as polylines, rendering the text useless for station labels and grid labels (for offsets and elevations).
The TML allows you to specify the text style, layer, text height, etc. and then specify a start value and an increment (like
station 0 with an increment of 100), and then rapidly click all of the section zero offset line end points to place station text on the cross-sections which can then be used to convert them into stored cross-sections or 3D lines. The "Template Text" defines how the text is computed. Using just "{}" will convert the compute value to a string without any decimal precision. If you want to include more precision, specify the number of decimals inside the "{}" text. For example, "{2}" would format the computed value with 2 decimal places.
If you want the computed value to be formatted as a station, use "{s}" for the "Template Text". Any extra text in the "Template Text" will just be included in the result. For example, in the attached image, the "Template Text" included the "Sta " text.
