Hi
I switched to v4 and have not had any issues with the layers…make sure your condition layer (demolished,existing or new) is nested accurately as the plan generator is very sensitive to this. Keep to LELC…Level,Element,Location,Condition.
You can even try the configuration to customise your own layers ,line weights and scenes to fine tune your drawings…for example to create an Elevation that shows parts of the building to be demolished.I must say you have to understand the system of grouping/nesting/layering throughly before you tackle customisation….the effort is worth it to fully get the most out of CONDOC V4.
