Revit divided mass with custom family giving a 'spike' look

I was trying to follow a video on how to do the gherkin which requires a special frame family that when i input into my model makes it look like theres spikes. (Left is tutorial Right is Mine) please help me. The tutorial can be found here: https://www.youtube.com/watch?v=EmNgjMpn7bk at around 11:20

What's your "Border Tile" Parameter set to? "Overhanging"? "Partial"?

They are set to partial. I tried Overhanging but thats not what im looking for..

Try a slight All Grid Rotation value and report back. 

 

...seems to do the trick here. One side positive and the other side negative.  Maybe you missed that part in the tutorial?  I didn't watch it, so I don't know.

It comes down to how you create the curtain panel pattern based or adaptive panel family (not sure which one you use).  The geometry of the sweep should stay inside the path so you don't get 'Metallica spikes' at extreme angles.  See example below:

Another example using round profile and ball connector. 

Revit 2022 conceptual mass family is attached with both panel types.

Doing a negative grid location causes some of the triangles to be deleted.

Im not entirely sure what u mean by the geometry of the sweep should remain inside the path.. I just followed the tutorial exactly... Are u able to check my file?

You did not follow the tutorial 100% :)... you have to bare in mind that the guy who created such tutorial is not really genius and it did not come out spontaneously. He rehearsed it several times to make sure that it works when he records and casts. Otherwise he would look like a Boss. After all, Pattern Base Panels are designed and modeled to fit a specific conditions

  • The specific Form
  • And a defined pattern/GRID...it adapts to some extent but it is not meant to fit all conditions

 

That being said, I have just noticed your other post on how to revolve the form...Notice the pointy tip of that form you have, and go back to that tutorial and watch carefully the end of the spline. Such pointy and acute angles cause the panel either to deform or to cause an error forcing you to delete it => the source of the spikes at the top. To mitigate that you have 2 options:

  • Kill the point bullet top by detaching the Spline from the axis of the revolve
  • Reduce the Section of the Profile so that it works with those nasty slim pattern triangles at the top

For the Panel...I have nothing against the square shaped profile and/or modeling both frame and glass in one pattern based panel, but personally I would use

  • a Triangular Profile. 
  • and I would nest 1 family for the Frame and another for the Panel (not 2in1)

Detaching the spline doesnt make a difference using my original frame... Upon using the new triangle frame it creates an even more absurd spike

Maestro... The form you have created is not the same as his (the guy from tutorial) ...SEE GIF BELOW...

  1. I used the frame you uploaded
  2. applied to a shape similar to that in the youtube you provided ca. H:176m and Base 52.5m!!!

Result: Identical

 

Match his inputs and your model will look IDENTICAL to his....EVEN THE SPIKES AT THE SECOND GRID FROM TOP which you can see at Frame 11:54 of that youtube (see screenshot below the gif taken from youtube and compare yourself). It is not rocket science

Piece of advice: look for better tutorials ... that one has been cut and edited several times and mimicking such tutorials wont really give you a good foundation for advanced modeling

Below is what I mean.  Left is when a profile centered on the path, right is when a profile is inside the path.

If you insist on keeping the profile centered on that path, then create a frame from a segment of the path, not from the triangle, then place a 'connector' at each corner.

Both types are in the Revit file I shared yesterday.
