Hi, I try to create a vault structure by the part builder tutorial of civil 3D.
The tutorial site : https://knowledge.autodesk.com/zh-hans/support/autocad-civil-3d/getting-started/caas/CloudHelp/cloud...
But in the step 23 of exercise 2 - Right-click Modifiers -> Add Boolean Subtract.
I find that problem(following photo): the Boolean Subtract function of Modifiers could not be used....
My civil 3D version is Autodesk Civil 2019 Student.
Is not this version provide this function?
Or I need to set some setting before I use this function?
Thanks for anyone's help!
Emmm.... I'm very confuse for this question...
Can anyone help me?
