I will attache a .VCE file here with a corridor and one template. Is someone can import it and see what i am doing wrong here. I get holes in the corridor at different places and it seems like it has to do with my alignment, but it does not occur everywhere. Its 2 surfaces, Finish and subgrade "Terassbotten". At one place the whole last slope is missing in the model and i cant fix it.
I cant change my alignment because thats a line wich is used in many other projects so i need it to present the correct station. Thats why i have my own line in the middle wich i am constructing the corridor from.
We are going to deliver models to machines and it would be nice not to need to export the surfaces and import the again as poly 3D to fix it every time.
