Question Regarding Eaves.

Anonymous — Wed, 28 Feb 2007 22:36:33 GMT

Hi,

i have been trying to sort out which way is the most efficient way of creating proper eaves with timbers, facia, fibro board etc for a residential house so that when i do a cross section the eaves will be accurate. Any help would be appreciated thanks.

What version of Archicad are you on and what add-ons do you have? (You might want to add that to your signature, since it will be a common question for any problems you ever have. Features vary a lot from version to version).

In that case, (as odd as it sounds), I like to use the profiled walls to make soffits/fascias.

Not odd at all - I believe it's the best way to go. It allows creation of rebates and chamfers etc.

Once the facias and soffits are in place I use them to cut the rafters using s.e.o. because the rafter objects never seem to terminate in the right place to begin with. I make similar cuts using beams as purlins and wall plates so that by building up the elements like this the resulting sections need little or no 2D "adjustment"

Forgive me for jumping in Tom. I just happen to be online.

Profiled walls can only be level, but you can use an inclined profiled beam.

If you use Beams instead of Walls, yes.

To give credit where it's due, I believe that Graphisoft have given us the tools to do this job quite well with profiled walls and beams. That wish is very old and AC 10 now copes pretty well with facias, cornices, friezes or entablatures in my opinion.

To have a specific tool for all the less common parts of the building would become very cluttered and I feel that it's better to make more imaginative use of the modelling tools we have. The best tool in the tool box is usually the one that gets used the most.

Agreed, the tools are there. ... and I think fascias are a pretty common part of buildings, at least those that have roofs.

I'm not wishing for a new tool.... just a new feature for an existing one (roof).

Wouldn't it be easier to create and edit roofs if the fascias were defined as the roof edge?

Yes!! This has been on my wishlist for some time.

Yes I understand and I agree that it would be very good to have more functionality within the roof tool. It is a little basic as very few roofs are just an inclined slab.

I would like several enhancements including the ability control the roof surfacing and edge profiles. The roof surfacing accessory does some of this but the availability of different surface profiles limits its usefulness and it is impossible to create custom ones unless you happen to be a very experienced GDL programmer.

Other features for the roof tool could be the ability to create box gutters, lead work flashings and, as you said, fascias and barge boards.

Is all this an existing wish or should it be added to the list?

Here's a novel idea......extend the ability to use custom profiles to slabs and roofs..... It would solve two long-time wishes we have had.

BTW I use a beam profile for fascia, soffit, eavestrough and frieze. I can cover most conditions just by drawing with a beam.

I am still working mostly in AC9 (AC10 transition has been slow), can you direct me to the best place (ArchicadWiki, Manual, ArchiCAD 10 Interactive Training Guide ...) for learning and practicing these technics?

First try:
http://www.graphisoft.com/products/archicad/ac10/demo/
for new features in general

Link to:
http://graphisoft.vo.llnwd.net/o1/AC10/ACClips/AC10_12.mp4
for specific intro to custom profiles

Also look in help menu under ArchiCAD new fetures guide and in ArchiCAD help enter a search for complex profiles.

So if you are using saved profiles (Say a 2x12 Fascia & a 1x6 Step Fascia) to create a fascia detail at the eave, can the saved profiles be rotated for a Rafter Square cut? Or do I have to save a different profile for every different roof pitch?

I was attempting to use the Cadimage Profile Tool in AC9 but I ran into the problem of having to create different profiles (Fascia) for each Roof Pitch. Also the "Clean-up" with the gable end was not correct.

Here is a Thread post of the kind of Fascia Detail I am trying to do. I am currently just using roofs.

And Yes, the Square cut tails of the rafter objects do not show in plan the length to the top of the rafter, but to the bottom. This is not what I want on my framing plans. Wish

I save one profile containing the fascia & eavestrough and then modify it as needed to add the soffit and frieze. The neat thing is, the profiles don't need to be saved at all. I can modify one segment and simply apply the profile and move on to the next.

I looked at your pictures on the other post. It looks as though they are rectangular in profile.

If I was modelling these I would probably just use the roof tool because it's the quickest and it gives an accurate result in plan, section, elevation and model. The extra time involved in creating a custom profile is, for me, only justified if the profile is complex, like a classical plinth or such like.

Until we have a more versatile roof tool which can model edge details and profiles, that would be my advice.

If you need more complex cuts at the ends of your fascias, could I suggest looking at an add-on called Objective.
