What are the steps to create Groups?

  • Groups can be created by selecting from pre-populated common ones from the Type combo box or by selecting New Group, New Room Group, New Window Group option.
    • Once the name is selected or input on the Name text box, Create button should be pressed which offers to select items to be added to the new group.
    • Room or Window group automatically filters only room/window when adding items.
    • Any  item under a category which is ticked on the exclude list is ignored when selecting items to be added to the group.
      • Some categories such as Plumbing and Furniture are always excluded from the groups by default.
      • If those items need to be added to a group, they can be unticked from the exclude list temporarily.

What are the steps to Update Groups?

  • Remove items under certain category
    • Tick the categories on the exclude list and then Select the Group name and then Update button.
    • Any items under newly ticked categories will be removed from the group.
  • Remove items by selecting them
    • In order to remove items, press Remove button and then select the items to be removed from the group.
    • In order to remove items by selection, the category which a item belongs to must not be ticked on the exclude list.
  • Add new items to the group
    • To add items by selection: Press Add button and select elements from the model to be added to the group.
    • In order to add items under a category: Untick the category on the exclude list first, and then press Add button to select elements.
      (unticking a category from the filter list would not automatically add category elements to the group.)

How to exclude objects from Revit Links?

  • Revit Links are inserted as single object to the group so it is not possible to exclude objects when adding them to the group.
  • They are filtered at the conversion time based on the exclusion list.
  • Tick the categories on the exclude list and then close the group dialogue. The list is saved on Project settings and will be used on conversion time.

How to exclude objects from Imported Autocad DWG instances?

  • Autocad DWG Links are inserted as single object to the group so it is not possible to exclude objects when adding them to the group.
  • However it is possible to exclude objects by layer from the import instance itself.
  • Select the imported dwg instance and then Click Modify and the Delete Layers. Select the layers to exclude and Press Ok.
  • Refer to Revit help topic “Delete Layers in CAD files” for step by step guide.

Which groups should the windows be on?

  • Windows should be added to the group where they exist.
    • Windows on Proposed buildings should be added to Proposed group.
    • Windows on Surrounding building should be added to Surrounding group.
    • Any windows on Existing buildings should be added to Existing group.

What are the steps to register Revit windows?

  • Standard Revit windows and doors and curtain panels with glazing can be registered as windows.
  • Open Register Dialog and go to Register Mode then Window tab.
  • Detect All Levels button shows all the windows which can be registered. Users can also pick windows to register by using Select Manually button. Any windows which are already registered will not show up here.
  • Register Windows button registers the windows which are selected on the data grid.
  • Window Id
    • Building Name is read from the Building combo box.
    • Floor name is read from the Revit Level where the window is placed. If Revit Level is not defined then the centre of the window is used to detect the correct level name.
    • Window name is read from the Revit Paramter ‘Mark‘. If the Mark is empty, UnNamed will be used with a counter.
  • Window Normal
    • The normal is decided by intersecting with room or floor in the direction of window facing orientation then on the opposite direction. It handles the situation when window/wall flipped are incorrectly.  If there is no room and floor then window’s facing orientation will be used.
  • Shared parameters
    • Some of the window properties are added as shared parameters in the model and they can be updated via Window tags or schedule.
    • Building name, description, property type, glazing transmittance, adf, vsc and apsh offset values can be updated.

What are the steps to register Revit Rooms?

  • Standard Revit Rooms which are placed in the model and are correctly bounded by walls can be registered as rooms.
  • Open Register Dialog and go to Register Mode then Room tab.
  • Detect All Levels button shows all the rooms which can be registered. Users can also pick rooms to register by using Select Manually button. Any rooms which are already registered will not show up here.
  • Register Rooms button registers the rooms which are selected on the data grid.
  • Room Id
    • Building Name is read from the Building combo box.
    • Floor name is read from the Revit Level where the room is placed.
    • Room name is read from the Revit Paramter ‘Number‘. If Number is empty, UnNamed will be used with a counter.
    • Room type is read from the Revit Paramter ‘Name’. If the Name is empty, Undefined will be used.
  • Ceiling Height is set at time of registration based on ray intersection of the nearest ceiling or roof. If this method fails then value defined in the register dialog is used. It can be changed later by simply modifying the shared parameter property MBS_CeilingHeight  on revit room.
  • Shared parameters
    • Some of the room properties are added as shared parameters in the model and they can be updated via Room tags or schedule.
    • Building name, description, property type, required adf value, adf reflectance values, ceiling height and grid spacing can be updated.

How to specify offset values for VSC, APSH and ADF?

  • The reference calculation point is on the Outside face of the wall for windows hosted on the wall and on the glazing itself for the curtain and door panels.
  • Offset value should be positive to go towards the room and negative to go away from the room
  • The VSC and APSH offset values are read from the textboxes but ADF offset value is set based on the type of the window and/or its host as below. The offset can be updated later on the Update mode.
Window Type ADF Offset
Windows hosted on Wall/Roof Half of the Wall/Roof width
Curtain or Door Panels 0

Can room/window groups be automaticaly created?

  • Yes. Register dialog/Create Groups

What unit is used by the software?

  • Meters. If the model is in millimeters, Registration and conversion process would take forever and/or give error. Model must be scaled to meters.

Why the graphical results are not saved in the model?

Room point based calculation results such as Daylight Distribution, Daylight Factor and Climate Daylight, are graphics and NOT residents of the database – so they don’t add to the size of the Revit
model and they don’t persist.

If you want them again later you need to rerun the calculation or load back the saved results using Load Results dialogue.

How is the target area calculated for room point based calculations, from the graphical result?

The target area(as in the exported report) for Daylight Distribution, Daylight Factor and Climate based calculations might not tally up exactly with the graphical results visible in the model.

This is due to the fact that the Waldram Tools software uses Autodesk® Revit Analysis Visualization Framework to represent the graphical result on surfaces while the calculations are done in MBS.

The target area for

  • Daylight Factor and Climate based is simply calculated by (equally weighted)averaging the calculation points result within the room area.
  • Daylight Distribution(No Sky Line) the contour is interpolated from the points result(in the same way as in Waldram AutoCAD package).

How is the window frame affecting the calculations?

  • It would not affect calculations, such as VSC, where the sensor is located on the outer face of the window.
  • The frame if presents blocks the view and daylight for all room point based calculations such as Daylight Distribution, Daylight Factor and Climate Daylight.
  • For ADF where the calculation point is behind the glazing by a small offset the frames do not take part in calculating the Sky Component(and to eventually derive the theta angle) as there is a chance that the sensor gets blocked
    by part of the frame. The frame factor therefore is set to 1 automatically for registered windows. And (to compensate) the glazed area is exactly calculated as the sum of all the glazing elements in the window.

What transparency value should be used for Waldram image?

  • Transparency: 0 = When overlapping, Proposed on top, Existing Hidden
  • Transparency: 255 = When overlapping, Existing on top, Proposed Hidden
  • Transparency :155 (or anything in middle) = Both visible

Highlight Room Interiors

  • To visualizes the process you can try the “Highlight Room Interiors” utility on the Waldram Tools ribbon toolbar which paints the interiors of all the Revit Rooms in three different colors for floors, interior walls and ceilings.

What are the steps to register a facade and run the facade analysis?

  • Select the faces to run the facade analysis and then press Register Facades
  • They will appear as a group for calculations such as VSC and APSH.
  • Run the calculation for the selected facade group.

  • They can be saved as an Image. Right click the view and Save to Project as Image. The image will be saved under Views-Renderings.
  • The full results can also be loaded to the view by going to Calculation dialogue – Tools- Load Results and then selecting the .Out file for the facade result.

How can I assign materials to surfaces for ray tracing calculations?

Material Dialogue is possibly the easiest way to assign material to surfaces. The Layer name box is populated with all Revit Material Library including three MBS specific materials:

“MBS_InteriorWalls”

“MBS_Floors”

“MBS_Ceilings”

The indoor surfaces, ceiling and floors of all Revit Rooms(either MBS registered or not) will be detected and pick the assigned material from this table during the conversion process if any record exists.

To visualizes the process you can try the “Highlight Room Interiors” utility on the Waldram Tools ribbon toolbar which paints the interiors of all the Revit Rooms in three different colors for floors, interior walls and ceilings.

Another way to apply material is to select Revit elements and use Revit Paint tool to directly apply material to the face of the element. This way no material assignment is required through the Waldram Tools Material Dialogue.

Why am I getting "Cannot modify group" errors?

  • The Revit model groups don’t like if object within a group is modified without entering the Edit group mode. And Revit API doesn’t provide simple option to edit groups in order to modify objects.
  • It is highly recommended to avoid putting Windows and Rooms in such groups to avoid errors.
