Everytime i try to insert a .dmx file for the airfoild for the planes wing. I get this error message "The DXF/DWG imported with the following error:
- Could not import unrecognized entity." DOES ANYONE know how to fix this https://cad.onshape.com/documents/1186b7ba783480919ff0bbd0/w/ccd66d15efeebb87b376e1b6/e/098dad38282d4e9186efc4dc

What is a DMX file?
I would expect all supported files to appear in this list. If it isn't, that might explain it:

I've only run into issues with .dxf imports when there's an egregious amount of data or something in the file that's broken from the export from the outside software but either way my recommendation would be to use the airfoil custom feature to generate your profiles instead of relying on an imported .dxf. https://www.onshape.com/en/blog/streamlining-airfoil-design-custom-features
Derek Van Allen | Engineering Consultant | MeddlerThank you guys for the feedback. The thing is I need a book for the HAVF fomat of the B-52s airfoil(s). However I could not find the airfoil I needed in HAVF format. So I was forced to use an outside utility that allowed me to download the airfoil I needed. Also I do not know why I put .DMX when I had attempted to import .DXF so that is my fault. If you find or know any other workarounds please let me know.
You could import a formatted text file with point coordintes and build a spline on it. There is an older feature script called JSpline to do this, or another one that takes CSV files and is called CSVxyz1. It may be easier to fiddle with bulk text re-formatting than with DXF file import.
thank you @martin_kopplow I'll try it out
ok, I checked it out and for some reason i was able to add "Jspline" in the add custom feature thing however i dont know how to view the .dxf points in order to put them into the featurescript. I was able to add the CSVxyz to it, however whenever I import the csv file it says it couldnt regenerate properly.
IT WORKED!!! I was able to add in the spline using the CSVxyz featurescript after I found one with xyz coordinates. Thank you so much!
