Please help with toposolid from a csv file

[IlmariLuutonen]

I get 2 errors when I try to create a toposolid from a csv file

1. no points were found in the file

2. some rows from the file could not be used

I've tried to removing decimals completely and I've tried removing the first 3 digits of the x and y columns but neither worked. I suspect the points are just so extremely far from the origin point that revit doesn't like it but am not sure.

The problem is that your numbers are separated by a semi colon (;) not by a comma (,). When your file opens in Excel, all your numbers are in the same column A, instead of being in columns A, B, and C.  Use Search and Replace to change all semi colons with commas. Then your file should work.
