Bespoke door opening in section

What is the best strategy to create a bespoke door family, when the opening at the head has two levels? The screenshot shows the opening in section:

The same way you model any door but instead of using the OOTB Opening Cut (Shown in the image below...Use a nested Wall or Face Based Void family. And use that to cut the Host in the Door family. This way you can form the opening in any shape you wish and give it any offsets/recesses you desire.

 

NOTE: you can model the cutting void in the same door family HOWEVER I have noticed that these might/could create an issue when exported to IFC ... When having joined walls, which allows a door or window to cut through both walls, if the opening void is modeled directly in the door, the cut opening generated in the non-hosting door sometimes is not exported to IFC.

thank you, appreciated

 

so I would not start with the door family template, but with another template? metric generic model?

would you be so kind please and describe your steps more specifically?

I need the head dimensions at the top to be parametric.

 

I could not do any additional cut when using the door template, I was getting a message that there cannot be two voids or openings in the same host.

You start with the door template...the door family template uses by default an "opening cut" which is a line placed usually on the inner face of the host/wall....you can parametrize it as you wish 

 

  1. Select the opening cut and delete it
  2. Start a new face or wall based generic model
  3. Model the void to the shape you need similar to what you would do if you model that in-place (use reference lines constrain the recesses and set the parameters needed to control width, depth, height of the void)
  4. Use cut so that the void cuts its host
  5. Save this family
  6. Go back to the door family template and Load the above void you modeled in 
    • place it on the face of the wall if it is face based
    • host it in the wall if it is a wall based
  7. Constrain the void family and associate its parameter with the relevant parameters in the door family 

 

Below is the same modeled in place...in the door family...above I am suggesting that you model the same void in a wall based family and nest it into the door family - If nesting is too hard, just model it as per below GIFF strain in the Door template
