create a diagonal facade using mass surface pattern

[Anonymous]

 Hi, i wanted to design a diagonal facade. I used in place mass to create the form and chose 1/3 step as the facade patter. i did a new family for it but it seems to have some lines on the panels. Can i know how to solve it? Thanks

I'm not following. Post your file so we can how you are doing it.

I think I figured it out.  You need to create a Pattern-Based Curtain Panel Family that uses the 1/3 Step Pattern. Sounds like you did this already. Now, you need to load your Pattern-Based Curtain Panel into the Mass Family with the Divided Surface, select the Divided Surface and then change the Pattern from 1/3 Step to the Pattern-Based Curtain Panel Family you just loaded.  It will be listed in the Properties Type Selector under 1/3 Step Pattern. 

How'd I do?

Hi Sir, Yes i did what u say. But i dont know why the curtain panels seems to have the lines on it. Is it because i rotate the pattern? and will it affects when it comes to rendering? 😥

The Panel Geometry isn't constrained properly.  

...if I remove everything but the "mullion" geometry from the Family, it looks correct in the Project.  

Make sure all your Family geometry is hosted and constrained to Adaptive Points. The geometry of the "panels" in the Family are not.  Are you familiar with how to host Reference Points to other Reference Points?

Hi sir, sorry i dont really know how to constraint it. 😥

It is just a basic geometry, if four points are not on the same plane then they will form two planes, each from 3 points.  Hence the diagonal lines you see.

Below is an example, when one point is out of plane then you will have that condition.  You facade is not flat so obviously you will see a lot of this.

I see. I redo the facade and it has a smoother curvature now. Then is there anyway to solve the problem that u mentioned jus now? and can i know how to constraint it to the adaptive points? Thank you very much!

Here is a roughly revised family applied on a mass in you project.

OMG sir its working! THANK YOU SO MUCH!! i really appreciate it 😭
