I want to create contour lines from Google Earth on AutoCAD. I have done everything shown on YouTube, but once I opened the file in TCX converter and clicked on Track Modify, I have been unable to update altitude. Do you know why?
Unfortunately, you still need to use the tutorials listed through Google Search. I have watched the video tutorial from YouTube and the user successfully creates the lines. Try watching it again and follow his directions closely, because most likely you are missing an important step.
