Generative Components Tutorial - Modelling The Gherkin

Hi All,

I finally uploaded the first part of a 3 part series on modelling the Gherkin in Generative Components.

It explores some of the techniques I have used throughout the year on various projects.

Thought I would share it with the community first.

Wish everyone a Happy Holiday and New Year!

  • Hi All,

    I have just finished off the final part of the Gherkin modelling series I started last year.

    Hopefully you will get something out of the series.

  • Great vid, Wayne !

    Some questions:

    1. I wonder if Parametric Cells can be used in lieu of GNT's? This would theoretically allow some flexibility to modify the panels after the GC model has been exported.

    2. Exporting: an hour to export? Why so long? Isn't the model already on screen. What is happening behind the scenes? Probably a question for Jeff Brown.

  • Hi Dominic,

    Thanks for the comment.

    I agree, when the we can utilise the Parametric Cells in GC it will completely change our workflows. We currently have multiple GNT's that could be replaced with simple Parametric Cells, not only would it speed up the process and reduce the file size, in delivery we can then schedule the panels as an item rather than the current situation where we have individual object for each panel which makes it difficult to deliver. We have had some success in running another process that then converts the placed GNT into a cell but on a large building it creates so many cells it starts to become a management issue.

    The other benefit would be the reduced time to export IFC, shared cells save so much time on that end.

    With the export I believe it is a bit of both the laptop I was running on and the solids. However it isn’t a slouch and has 32gb of ram.

    What we have found is there is a memory issue with solids overall which could extend back to platform level. In some scripts that we run a recursive transaction to say process facades floor by floor the memory expands and doesn’t flush out and requires a program restart. Given this is probably due to the older solids (I don’t believe the new parametric solids are supported in GC update 6?) focus is probably better spent developing those than fixing the existing solid issues?

    Hence on some of our workflows we are now moving the surfaces to keep memory in check J

    I am heading up to Singapore next week, would be great to catchup.

    Thanks
