Being a relative new comer, I have come across a challenge that I cannot seem to solve. I’ve imported an IGES file into Rhino and would like to make a modification by removing part of the tail of this helicopter model. I’ve trying using the split command and cutting plane but once done, I am not able to select the Helo to complete the command. Please see the screen shot.
Any suggestions would be appreciated. I can upload the file but it pretty large and thought there might be a simple explanation before doing that.
Thanks in advance for any help!
