Hi Denis,
all the required rebar sets of one layer should be generated for the whole slab at once, so there’s no need to generate reinforcement of one layer multiple times.
If it doesn’t work correctly in your project, you can send me your Revit project and Robot Structural Analysis file to investigate your problem.
Please upload your files at a file transfer service of your choice or send a mail to support@sofistik.de.
Kind Regards
Lena
