I’m working in AutoCAD Plant 3D 2026 and need the ISCO SDR11 HDPE piping spec to behave properly. At the moment the program simply refuses to model flange connections with manual created equipment. I have the ISCO datasheets and a half-finished spec, but I need an expert who can open the Spec Editor, correct or rebuild the catalog, and hand back a file that lets every nominal size route and connect without errors. All these remotelly connected for fixing Deliverables • A fully functional Plant 3D 2026 catalog and spec for ISCO SDR11 HDPE • A short demo model proving that all components connect cleanly • A brief write-up or screencast so I can maintain the spec later Please work directly in the 2026 release to avoid compatibility issues. If you know HDPE fusion fittings and the quirks of Plant 3D catalog creation, this should be straightforward. I’m ready to test as soon as you send the updated files and eager to get my model running smoothly again.
