Complex Roof... HELP!

[griggadee]

Hi folks,

Ok, check out the attached picture of a complex roof that I need to model for my working drawings. The roof features dual pitches on a number of the sections, i.e. an element is pitched in two different planes at the same time. What is the best way to model these elements? I have imported the roof from a sketch up model, but it has no mass (depth).

Ideally I can do it with the roof tool so that each element has mass.

Any ideas?

Thanks

Two ways that I know comes to my mind right now.

In common with the two ways
- Convert to morph (this will let you snap to the point of the geometry)
- Make a mesh and match the shape and points of the geometry.

After that you could do one of these:

1- use the goodie mesh to roof (you'll probably need some adjustment after that)

2- copy the mesh down (distance will be thickness), then do a substraction (top one as target element), and finally convert the resulting mesh into morph. (with this method you will probably have better geometry but you won't have all the roof tool options).

Hope that Helps

Convert the imported sketchup object to a morph.

You can draw the roof in 3D window, it will figure out the pitch by clicking 3 points (snap to the morph). You'll end up with a whole bunch of single plane roofs, as long as they are using the same composite/thickness, it's a matter of CTRL/CMD clicking the edges to connect them if needed. The connections will be mitred by default then.

You might have to move the roofs up or down, depending on if your sketchup model is the bottom or top of your roof.

Thanks for the suggestion arqrivas, a close workaround by the looks of it, but not entirely what I was looking for.

But Erwin Edel, you are bang on the money! Your suggestion worked perfectly! I was air high-fiving you last night when I tried what you said and achieved the result I wanted (see attached). Thank you so much!

Brilliant support from the Archicad community as always! Thanks guys.

Amazing!

I didn't knew you could do that in AC, obviously Erwin's solution is the right one.
Even I'm going to practice that when I have some time.

You can also model it with the Mesh Tool with 0 thickness and then use the "Convert Mesh To Roof" Add-On to create all the roof.
