Does someone know why there is a issue when i create the solid ?
Civil 3D 2020.4
it works just fine, you are not up to date, learn how to ask the right questions and PLEASE do not draw your conclusions because 99% of the time are wrong.
I am sorry about that. It’s ture it works when i am update my Civil 3d, i just haven’t thought about it.
Still thank you for your response and all you have done for the CivilToolkit, it’s a amazing und powerful Toolkit.
