Casework door will not flex

Casework door will not flex

Hi,

 

I am trying to create a casework family for an upper corner cabinet with a diagonal door. I had brought in a door from an existing family. When I create different types with different heights, the door will not flex along with the case. I have tried to nest the door family, copy and paste the door, and nothing helped. Any ideas?

You need to reassign parameters and constraints for your nested door family.

You need to associate the door family's dimension parameters with the host family's parameters.  Example below:

Nope. Still not working. Now it says that it can't create the Door family.

You assigned the door height parameter to the casework height param. correctly, but the door family itself is falling apart. Flex it, make sure to apply all constraints.

FYI, it is better to create a ref plane skeleton first, create parameters, flex it and then create geometry and lock it to the ref planes. Locking geometry to other geometry is not the best approach.

I created a formula for the geometry to flex correctly when you increase the door Width.  I am a bit busy to fix the model but I think you can take it from here.  Let me know if any troubles.

Thank you! I re-created the Door family and reloaded it. Awesome!

One last question - would there be any way to make this sit on corner walls without too much hand-eye coordination? The way that out-of-the-box casework families grab hold of walls?

If you created it as a wall based or face based family then it will hosted by one wall or one face when placed in the project. You still need to align it to the other wall so that it sits right at the corner.

The one you have is non hosted. So you need to manually align the back reference planes with the corner walls one by one, or move it using endpoint snap.

The formula works beautifully. I changed it so that the casework size flexes when we keep the width constant and input the desired end width. A question - can you explain why the square root of 2 was needed?

pythagorean triples:
a: length of short sides of the triangle
b: length of long side of the triangle

a2 + a2 = b2
a2 = b2 / 2
a = b / sqrt (2)

Can't believe I missed it! Smiley (Zunge)

 

Another question - when the new value of EndWidth comes up, the geometry at the angled face does not flex. Quite simply because the end of Depth (it is now a reference line, which works no better than a reference plane) is not locked to the diagonal reference planes. This is what I get when the value of Depth is changed from 2' to 1'9".

Any attempt to lock the ends of the reference lines to the reference planes at that intersection make Revit say that this would over constrain the sketch.

Hey all... @Sahay_R

 

I hope you don't get me wrong but after having a look at what you attached,  that family (with or without that formula) is a disaster...starting from the whole down to the nested doors and handles

 

Using formulas for that purpose is not the ideal approach, it is not wrong but to get that family to flex properly with the nested elements one shouldn't need a formula..  Forcing Elements to resize using formulas means more computation where it is not necessary, means more complexity, means less performance, means less likely I would use such family as a 3nd choice. And most likely the family will break again and you will need a new formula to fix it!

 

The proper solution is more or less what @PijPiwo suggested and you should start off from the handles to the panels to the cabinet. And while at it, you might want to

  1. consider using Family Type parameter for the panel instead of all those visibility parameters
  2. and try to lock geometries to reference plains and label the dimensions to those planes rather than constraining to other geometries.
  3. and model the nested panels neutral without elevation
  4. optional: I would nest the handles into the host rather than the panels but if you nest them into the panel also lock them to ref planes
  5. try to use a consistent family category instead of once generic and once casework ...etc

Of course it's a disaster! If it worked I wouldn't be posting here!

 

Sending it as is to Interiors for use - it works beautifully - disaster or not - for the 24" depth. For the 21" depth - I may start over just for the purpose of education. Or I may not. Wish me luck.
