Screens as Automatic Wing Walls

Using Hero’s automatic detection of Screens as Wing Walls feature, is a highly recommended way to improve your productivity and reduce data-entry errors.

This unique feature can be slightly confusing to new users who are used to more Manual Wing Wall style creation experience from other software packages.

It is also slightly different to how Screens are used as parallel Vertical Shade Objects (i.e. their “traditional” functionality as Screens inside Chenath) inside Hero where you are required to manually attach them. You don’t need to do that for Screens as Automatic Wing Walls.

When you use a Screen to represent a Wing Wall(s) and let Hero automatically detect that Screen (as a Vertical Shade object) and automatically create a Wing Wall Shade object (used in Chenath), you give yourself much greater flexibility and accuracy.

Benefits of Screens as Automatic Wing Walls

1. Model the Screen dimensions and height once - then let Hero handle the vertical offsets and other calculations for each Wall connected to the Screen as a Wing-Wall.

2. Screens are commonly already required to be modelled as Parallel (i.e. traditional) Shading Screens for the same situation that require it to be modelled as a Wing Wall, so combine the two into the one Hero model object.

3. Design change flexibility - if that shade object height or position changes in the design, you again only have to change one screen height or width, with manual Wing Walls you update every Wall that has such a Wing-Wall.

4. Reduce data-entry error - it is easy to miss or forget to edit a Manual Wing Wall Vertical Offset dimension or Projection dimension when you are manually entering wing-walls for each and every Wall.

How To Use Screens as Wing Walls

Enter the Height of the Screen as you would for when using it as a Parallel Shading Screen.

If the Screen line is within a certain distance to the edge of the Wall (note it can be slightly “in front” of a Wall in which case Hero just caps the Horizontal Offset of the Wing Wall to 0mm) then Hero will automatically calculate and create an Automatic Wing Wall to visual show our best guess at the appropriate Wing Wall.

The Wing Wall projection, horizontal and vertical offset values are then updated automatically on model changes such as level heights and wall or shade object position changes.

Remember there’s no need to manually Attach Screens to Walls for them to be utilised as Automatic Wing Walls by Hero, we calculate and detect these automatically at the end of certain Hero actions! Attaching Screens to Walls is only required for Parallel traditional Shade Screen model creation where some user judgement is currently required.

When are Manual Wing Walls appropriate?

There's always a place for overriding wing-walls. The limitations of Chenath (only one wing-wall shade object allowed per wall end) require Hero to select just one of the many possible Wing-Wall shade objects configurations that are possible in a typical design. There will inevitably be times where user-judgement is required to provide a more human educated guess at what would be the appropriate shade object. In these situations, Manual Wing Walls provide a quick and flexible way to lock a Wing-Wall shade object to a Wall .
