Hi Matthias,
thanks for the documents. Just had a look at this. In most of what is written I am with you.
Just one remark. In your small example all MEP openings will be adoped in the TWP and ARC modell. I am structural engineer for concrete buildings. Means we do make TWP modells and parametric modell related drawings. We do include all openings in our TWP concrete model. We do make the buildings site model and the drawings for the foam work and the reinforcement. Means we have to include the openings. But non of the architects I have worked with has ever put all openings in his modell. Some of them have tried to input all openings but have given up after the third or even more change of the opening. It is just not worth to do because we do make the model for the building site. (Die Werkplanung für die Schalung und Bewehrung).
I am curious, if it is different in other projects. Someone around here who has done BIM-Projects in real world?
The most important part is missing. How is it possible to automate the process to get the openings from the MEP modell into the TWP modell. Or even more important because the later does work if ProvisionForVoid is used (at least it does in Allplan), how is it possible to automate the process of the changes of openings. The later is what takes the most time.
cheers bernd
keep up the good work. Hopefully the VDI does not want to charge every BIM-Workflow document with 75 Euros.
