I was digitizing a profile data from a DGN file into civil 3D. I was wondering if there is a faster way to convert directly the polyline profile into civil 3D profile. In the Pofile Layout Tools, there is Convert AutoCad Line and Spline but a message prompt that the "Selected entity cannot be converted." (Spline or Polyline) except for the line which is from the exploded polyline. The prompt also specifies "Select a line, quadratic spline to convert:" I am not sure and do not know how to create a quadratic spline. Only the one I know is just a spline.
Converting Line, Polyline & Spline into a Profile in Civil 3D.
A few links that might help:
Spline Command, SPLINETYPE, How to convert Splines to Polylines.
Can you post a drawing with one of the splines in it?

He attached a zip file, with a dll file in it. You would extract that dll to a folder, use the NETLOAD command to load the dll into Civil 3D then type PFP to run the command in that dll file.
Not sure why it didn't work for you. Did you use NETLOAD to load the dll into civil 3d?
It loaded fine for me, but I'm running 2019.2. Perhaps your version isn't supported by that app?
I ran it on the test file you provided and it worked, except the profile it generated was shifted to the right. I moved it to line it up with your polyline, just to verify it was correct.
