Why will this workspace not contour?

Workspace will not contour, could I please get a pointer as to what I am doing wrong?

I can’t tell exactly what’s going on from that screenshot. I opened your workspace and did two things

  1. disable curves only
  2. provided an area op alternative with specific surface selection

Thank you. What is happening is the contour is showing up on the bottom of the part not the top. I will have to learn the area op command.

interesting. your workspace opened and contoured properly for me. try opening the workspace in a private browsing tab and see if the behavior is different.

Yeah I did before I submitted a thread. Not sure but thank you so much for the help.
