Issue: When importing a point file into Civil 3D, there is a message in the import point dialog that reads: Import Points No point file format match found. This may apply to different point file formats, like CSV, TXT, etc. Causes: The causes of this issue include: The source point file is open while trying to sample it in Civil 3D. Bad data in the point file (i.e. extra periods, blank spaces or formatting issues). The point file format is not compatible with the one selected in Civil 3D. Solution: In order to solve this issue, consider the following: Make sure the point file is closed before importing it. Check that there are no unwanted characters inside the point file, like %,&,$, etc. Be aware of the format used inside the point file, so the corresponding one is selected in Civil 3D. It may be necessary to create a custom point format if the necessary format doesn&exist in Civil 3D. Check the following article that contains a detailed explanation on How to import point data from Excel into Civil 3D. If the issue applies to a single computer and the file can be imported successfully in another machine: Reset user specific settings for Civil 3D. See: How to reset Civil 3D to defaults. Repair/ Reinstall Civil 3D. See: How to repair or reinstall an AutoCAD installation. Note: Use a text editor (like Notepad++) to review the point file for unwanted characters and to confirm its format. (Ref: AKN)
