I am trying to import high-fidelity airfoil data in and create curves. The data is in a space-delimited text file, in inches with 5 decimal point precision. I am trying to create the upper and lower surface curves by:
Insert>Curve>Curve Through XYZ Points> I then Browse to the .txt file and select it. When it comes in, the values are truncated to 2 decimal places and the in is added to the end. The result is the upper and lower surface curves do not meet at the leading edge, and the precision of the geometry is not sufficient.
I tried changing unit precision using Tools>Option>Document Properties but this has no effect in the truncation problem.
Does anyone know how to get the precision in the curve created to match the precision of the original data?
There might be a better way, but here is what I have done. The data that I work in was expressed by convention as 0 to 1 of chord length, with y values (thickness being represented as units of chord length).
I had the same problem, so I multiplied out all the values by 100 in excel and resaved the text files. Then after importing I turned these into blocks with the suffix -100 so I would remember to scale them back down by that amount. I realize this is a workaround and that it should not exist as a problem, but that is how I resolved the issue. If you are working in inches, 1000 as a multiplier seems like a good start.
Best of luck
