Having trouble with complex profiles

Anonymous — Thu, 23 Oct 2008 01:52:54 GMT

Hi there,

I'm trying to create a concave, irregular wall somewhat similar to this one:

I am fairly new to making complex profiles and am struggling. Any help would really be appreciated.

thanks.

Sorry, just some extra information.. I can make the curve fine but i cant work out how to make the wall 'bubble'. here is another picture

See how the building 'bubbles' instead of just being the same curve the whole way through. Whats the best way to do this? Would i have to make different comple profiles and then add them together?

Cheers.

use custom profiles with a horizontal section instead of a vertical one..

liek this.. then u will need to flip it over so its in the right plan for a roof

Thankyou for the reply it's exactly what i was looking for. One question but, I can't seem to find the option to change the custom profile from a vertical section to a horizontal section.. I'm sure it must be right infront of me but I cant for the life of me see it..

You save it as an object.....

nah there isnt one.. you will just draw it in teh vertical plan, but assum its horizontal... then place it in vertical like a wall... then if u have that "objective" add on you can rotate it over.. if not save it out as a library item then re insert it and it will be rotated around from vertical to horizontal.. (if that makes sense? lol)

now that u mention it, having this as an option would be an excelent addition to archicad.

You should be able to do this with the curtain wall tool. Not only is that the type of structure, but you can free rotate it in 3D window to correct the orientation. This keeps the skin parametric

thanks for the help, I'm still having a few problems but. To save it as an object i've gone File, Libraries and Objects, Save Project As... Then i save it as a Object file. But i still cannot seem to rotate the object in 3D, it will only rotate in 2D... Would you mind quickly going through the steps once I have made the object please? I'm using archicad 11.

it will automaticly rotate it to horizontal once you save it as an object.

go to 3d view and setthe camera to be viewing it directly down like plan view before u save it

hmm just can't seem to do it.... I can get it to curve vertically and horizonatlly seperately. but i cant seem to get it to curve both vertically and horizontally if you know what i mean.. i must have missed a step somewhere. i'll keep mucking around with it and hopefully i'll find that missing step.

Re: Having trouble with complex profiles

when you save it as an object, you need to be looking at in the 3D window as though you are looking straight down on it as it will be when placed.
Check the help menu

Put your Archicad version and OS in your signature please.

thanks for all the help, I really do appreciate it.. I've now been able to do everything but make the profile curve vertically. As you can see in the picture it's only curved horizontally.

When drawing the wall, use one of the curved wall Geometry Methods so the wall is curved in plan (before being rotated when saved as an object), this should be slightly more than a semi circular shape in your case.

Take a look at OBJECTiVE - it has tools for bending custom profile or built-in steel objects to complex curves in 3D. The objects retain their intelligence too, no matter how they are bent, rotated, or cut in 3D. I've attached some images to illustrate some uses of the tools. You can find out more at: http://www.encina.co.uk/objective.html

Modelling the building in the picture won't be easy - I could be wrong, but external envelope doesn't seem to be comprised of regular arcs, i.e. it looks egg-shaped.

You need to understand that a curvy-durvy wall must be converted into an arched structure by converting it into an object - this is how the orientation is changed.

Use the information here to do it:

cheers for that Dwight, helped a lot.

A new problem I'm now facing is that I cant figure out how to change my background from grey to white... If i select the complex profiles it changes my drawing area from white to grey, which only began happening today.. How can i change it back so it looks like it does in the second picture? I cant see any of the lines that i draw if it's grey even though they are there..

cheers.

Don't worry, I worked out how to fix it.
