When you receive a drawing containing survey points from outside sources, many times they are not ready for use in your system. They are many times simple blocks with varying attributes (if you’re lucky) but almost always require some reworking. While there are times when you can use CAD block export to create a CSV file for import, your results will vary and it usually requires jumping through hoops.
A lot of old drawings (and some new ones created by CAD beginners) can contain text objects (along with other geometry) to represent points. The text is often the elevation but it can be the point number or description. Because the position of the text is NOT the desired position, putting the objects together manually (by picking and typing) could easily burn a day’s time that should not be justified as billable time.
