Cadimage Roof Coverings and Skylights

There have been a few oddities in the roof covering edges and how the interact with skylights. In particular, trying to get rid of the gutters in the skylight settings has proven a little tricky.

The first step in fixing this is to select the covering, go to the Cadimage drop down menu > Coverings > Edit Roof Edges. This is where the confusing part hits us. The roof edge was set to “None” for the top edge of the opening and “Junction”  for the bottom edge.Screen Shot 2019-06-21 at 11.32.24 AM.png

For some roof orientations and opening configurations, this becomes reversed; so that the bottom edge of the opening in the Edit Roof Edges preview controls the edge type for the top and vice versa.Screen Shot 2019-06-21 at 11.32.37 AM.png

The result is a roof covering showing correctly in the model.

Collision Detection

With the increase in MEP and Structural integration into our ARCHICAD models, we have started to explore the Collision Detection features in ARCHICAD. These have been baked into our template and explained in the BIM manual. For those who may be interested in trying this feature out, but are not using the current template, this video explains the settings:

Editing Elements

In the last two quick tip articles we looked at ways to select and isolate elements in ARCHICAD. In this video, I review the different options for editing groups elements in ARCHICAD. Selecting and isolating elements is very useful, but only in as much as it allows you to quickly model and manipulate the model.

The options for editing groups of elements are:

  1. Element Settings (Com + T)
  2. Selection Sets (Com + Opt + T)
  3. Renovation Palette
  4. Relink Home Story (Right click)
  5. Pet Palette (not included in video)

Here is the video on the first four options for editing settings:

Isolating Elements

Working efficiently in ARCHICAD boils down to isolating out only the portions of the model you need to view. Viewing the entire model at all times is inefficient and ineffective, since plans can look to cluttered, 3d can be too slow, and section and elevation views may show more content than is relevant to the work that needs to be done.

Isolating elements out is done by the following methods (and different methods may be more useful in certain views than others):

  1. By Selection
  2. By Marquee
  3. By Layers
  4. By Renovation Status (not shown in video below)
  5. By Filter and Cut in 3d Palette
  6. By Cutting Planes

The following video quickly covers most of these methods of isolating elements in plan and 3d.

Selecting Elements

Working efficiently in ARCHICAD is critical, but not always easy. There are so many ways to model or draw everything, it is hard to know if you are using the most stream lined process.

A few things can help speed up your modeling and navigation work. In a series I am working on for the next Lunch and Learn presentation, we are going to explore the following:

  1. Efficiently Selecting ARCHICAD elements
  2. Isolating portions of a view
  3. Editing elements and groups of elements
  4. Efficient modeling
  5. Efficient drafting and drawing

The first series is covered here in the following videos:

Selecting Elements –

1) Find and Select

2) Selections Palette

3) Arrow Tool Options

4) Marquee Tool Options

5) Selecting Elements by Tool or Element Type

Twinmotion Frozen?

I know this has come up in the TM lunch and learns we have done at least once, and Matt explained it to me in person, but until I actually experienced it, the “freeze up” didn’t really make sense.

I was working on a TM rendering yesterday and most of the functions and navigation seemed to be frozen. The issue was related to adjusting surface color. The Color picker palette can become hidden behind the TM application window if you click on the model before closing the color picker.

To fix the problem, just drag the TM application to the side or expose the color picker palette and close.

Once again, this is not a “computer freeze up” or even an application bug. If you have no mouse or keyboard response and can not switch apps or navigate basic menus in Twinmotion, that is another issue all together. This freeze up issue is indicated by limited menu access and navigation control.

Layer Intersection Groups

Here’s a quick note on the layer intersection group concept in our template. We use 4 numbers in most of our project layer settings:

Screen Shot 2019-03-14 at 9.54.47 AM.png

  • 0 is for layers that are hidden and should not intersect with visible items in a given layer combo
  • 1 is for layers that are set to intersect, and should be the most common, especially among visible layers
  • 2 is for layers that should not intersect with standard “1” group layers. Examples of conditions that may require a Group 2 Layer are:
    • barge rafters or sloping trim that needs to run in to perpendicular and horizontal trim (this always results in a messy connection)
    • walls being trimmed with SEO to a roof plan, whose trimmed portion is interfering with content above the roof
    • there are defualt layers for these conditions already set up:
  • 999 is commonly used for module content placed from IFC files received from consultants.
    • This is a variable not accounted for in our template, since IFC coordination is on a project by project basis
