BIM_SIG_027 Special Interest Group July 2013

In this meeting all we looked at was walls, Wall Styles, and assigning textures to wall. There are a lot of places for you to assign textures to walls, so the first part of the meeting is looking at those. The movie finishes with the best and easiest place to assign your textures.

Topics covered:

  • unstyled walls
  • applying a texture to a wall
  • texture by object
  • texture wall by overall/left/right/startcap/endcap/holes
  • wall style
  • wall components
  • classes on wall components
  • overall class on a wall, how this relates to wall components classes
  • turning off wall component classes
  • using wall classes in viewports
  • using class overrides on walls in a viewport
  • assign textures to the wall by using the wall style and the overall wall object

    • Thank you Neil. If you don’t take this topic slowly it is easy to get confused about assigning textures to walls. My favourite way of assigning the textures to the walls is to assign the textures to the components. This is a huge advantage when you are using wall styles with complex buildings, Because you can control all the textures through the wall styles and not have to worry about whether the wall is facing one way or the other.

  1. Around the 19 minute mark you discuss the parent / child classes of the wall and wall components. I am wondering what is the best practice for creating a Wall-Proposed class since it will be the class on top of my components (child) classes. If I create a simple interior partition wall, 13mm Wall board (0.05 class thickness), 89mm Wood Framing (0.18 class thickness) and 13mm Wall board (0.05 class thickness) and draw the wall as a Wall-Proposed, is it correct for me to think that the Wall-Proposed class should be 0.05 or thinner as to make sure the wall board is seen at its correct line thickness? I am trying to make the Wall-Proposed class function as a “container” for my wall assembly and not interfere with the line thickness I have used to create that assembly.

    • Hi Rob, I think this topic requires more explanation. If I get time I’ll write another blog about it. But to answer your question, the parent is the Wall, the children are the components, Which means that the Wall – Proposed class is assigned to the parent, the Wall – Component classes are assigned to the children. These classes are used for visibility purposes, but they may also be used the graphic style. I would say that the parent class shouldn’t be used for graphic style, just the children.

      • I understand that Jonathan, but the way VW is set up, the parent’s class attributes is displayed on top of the wall components which could override the graphic style of the wall component below. What is the best practice for choosing graphic attributes / line weights of the wall-proposed class vs the wall components classes? Do you make your wall proposed class thin or non print so it doesn’t appear thicker than the class line weight of the finished face of my thin wall component of gypsum wall board?

        • Actually, it would be good know the best practice for this, especially thinking of going from Schematic Design (when the designer will simply want to work with a component-less wall style) to Working Drawings (where an architectural technologist will want to show and dimension the very same sized wall, but now with its components showing.) Given that these stages are often handled by two different people, knowing the most compatible approach/workflow would be great.
