Creating a lookout with an tapered bottom

Anonymous

This may be simple, but I'm stumped. I'm trying to create exposed lookout beams under a roof overhang that have an angle cut to the underside, so the beam tapers in depth towards the end. How do I do this?

Thanks

The old fashioned way is to make the rafters with skinny roofs and then use long roofs at the bottom ends of the rafters with Solid Element Operations to cut the tails.

There are also ways to do this with complex profiles, roof accessories, add-ons or custom parts.

Cadimage have produced an object called "tapered rafter" which would do exactly what you want. It's a reasonably old object so should be available to anyone from their Archicad Select website.

Or maybe someone from there could put it in the Depository (wink wink)

(Having trouble accessing their website at the moment, so can't provide a link, sorry)

Cadimage Select site here

You may have to register. It used to be that content more than 6 months old was available free, but it seems now that you have to pay a minimum of $10 per month for the most basic membership level in order to download objects via a credit system. That stinks.

Instead of trimming using SEO, if you trim one rafter tail using a roof and trim BASE to roof.

An advantage is that copies of this raftertail will retain the trim. Unlike SEO, you don't have to keep the roof you trimmed with in the file.
Disadvantage is that you have to redo should the trim angle change.

Personally think the Custom Profile is a better solution.

Me too. Much easier to be precise and to alter all rafters subsequently IMHO.
