Thanks Gaieus,
I think the answer to your query is yes. When I load the data the ruby requests the selection of a point object in the dialog box. If I select Construction point the program runs fine. If however I select a predefined component from the list the program stalls with a message "Adding point 1/ 5262". Hope this clarifies my problem. If there's a way of exchanging all the construction points automatically for a component that would get round the problem.

Please can somebody help...
I have successfully used Cloud_V6 to import point data from txt files into SU7 free as construction points. Unfortunately it seems to get stuck on the first point when I try using a predefined component instead of the default construction point. Is there a subtlety in how the component needs to be defined or is it that this feature doesn't work in SU7 free?
Any help would be greatly appreciated.
