I also have problem with spooler module in E3D.
During add spool drawing, when i choose pipe, there is error massage (83,499) Unexpected internal SPOOLER error, could you help me?, its possible the problem come from design?
Try re-modelling your pipe...
For those who are using SPOOL module, I would suggest to take a look at the Pipe Fabrication tool set within Piping Discipline in MODEL.
That is a powerful, modern and up-to-date set of functionalities dedicated to pipe fabrication needs.
We are fabrication company , not authorized to Change the model (By Detail Design Consultant). this is pure Design Problem or there is any other problem related spooler.
