Gutter & Eave

As I like using the roof object (not slabs - article coming!) I needed to find a way of quickly replicating gutter & fascia and after my first effort gave reasonable results, I found that it was even more capable for the task than I first thought. I know that some have used structural elements for gutters but I like the wall object because;
  1. Walls cleanup automatically ( I put my eave 'wall' on it's own cleanup group),
  2. Every element can have different material applied. (you can only have two with slab edge styles – fascia & soffeit).
  3. Can be on their own layer and turned off in plan views, you can even assign different componants for different views for the same part if required. (we'll explore that one here).
  4. I can use the wall width to set my eave width (0 = no eave) which adds the eave ceiling in for 3D renders and sections.
  5. You can also use it with slabs and get multiple material assignments for rendering.
So to explain what I have done with no.3 I found that adding a nicely profiled gutter shape that gives me a nice shadow and shine line for a rendering adds far too many lines in an aecElevation. So by doubling up on the componant for the gutter (& fascia), I can turn on whichever componant will give me the desired result.  This is done automatically in your display representations.   For the elevations, my profile is simpler giving a cleaner elevation (actually should be simpler and cleaner than what I have shown here).

Now if you love palettes, unfortunately they don't carry the sweep profile, so I would usually apply this style by the old cut & paste method. If you do use palettes, you can select multiple eave objects (try using 'select similar') and apply the profile to all of them at once. Don't forget to tick the 'Mitre selected Walls' box so you don't have to do it as a 2nd step.

See the Eave wall style in action here (item no.2 in two of the images).

So again with the drawing of one line, I can have my gutter, fascia, boxed eave ready for rendering, elevations and sections.

Tip: Select your eave wall and right click for the add selected option. Unlike palettes, this does retain the sweep. So you can cut from a template drawing, paste into and then 'Add selected' around. My eave wall is set to be setout from the top edge of the roof and it's done in Iso mode though if you lock your Z, you could do it in plan.

Tip: I used to turn off the display of the eave style in plan view but then it couldn't be selected. Now by assigning it the invisibility plot style (Aec Standard.stb) I can see it but it doesn;t print.
