more or less, the steps are descibed in the previous post from epsilon.
1. create a new csv file (syntax see previous post)
2. run PD or PS on eMS.
3. select e.g. your working folder.
4. Importe eBop from file (change file filter to csv and select you file)
I renamed PmWeldPoint to just WeldPoint and got the same error you got when i did an import.
Try to rename to only WeldPoint and see what you get.
If i create a path and a location and convert the location to a SPOT end then export the path to an .xml-file the "class" is PmWeldPoint
When you create the csv file, if you right click and select edit (or if you try to import the text file in Excel from "Data" - "Get External Data" - "From Text"), the separator between the text is a comma?
The message you receive indicates the class attribute was not found in the file, which means:
1 - PmWeldPoint class does not exist in your customization (you need to check your customization settings using EMPlanner on administration tools). I don't believe this is actually the problem because you probably can see weld points from other sources or studies right? Did you check the class name of those weld points?
2 - The class attribute was not correctly read because of wrong separator in the csv file. This is really tricky when using excel, sometimes I have csv files that I need to re-open, click to save the file again, and then I can import correctly.
