Anonymous — Tue, 12 Jul 2011 11:50:36 GMT

hello there after last improvements in new version of archicad 15 i know doing complicated shape will not be problem so here my question simply how i can create chamfer box from all sides as you see in the image

You can do this using complex profiles.

If it must be a solid box, use this object: Cube Prim 3.gsm (Olivier Dentan)
Download it from here: http://archilib.od.pagesperso-orange.fr/

Note that if you make the top and bottom horizontal elements in the custom profile AND set the Horizontal STRETCH to only the horizontal parts, you can adjust the "Width" of the box to meet in the middle...

Tip: Make those horizontal legs as SHORT as possible... You can only STRETCH longer...

The flaw in suggesting a complex profile solution is wall placement:

When placing walls, a matching corner radius curves the corners.

You are correct...

It will struggle to make the curved corner... Done it many times with no real good result...

As shown in the Red Graphic, adding a cube in the middle will help the joinery...

A long-time option is ArchiForma from Cigraph which can fillet the top and/or bottom of various shapes as seen in the attached.

Unlike your cube, the side edges are right angles. ArchiForma itself does not have a parameter to chamfer them - they would have to be manually filleted in the extruded form.

Here is the fillet-all version of the shape via ArchiForma 2.0

Note again that the top and bottom fillet of 6" is parametric. The extruded corner fillet was done manually via the pet palette to all corners of the fill prior to having ArchiForma extrude it. So, if the fillet amount changes, the shape would have to be re-created.

Note also that you can see the polygons in this OpenGL capture. If you are using an external rendering package such as Artlantis, these facets will be smoothed out.

Cheers,
