Can I get round edges on slabs ?

Anonymous — Thu, 25 May 2023 15:51:28 GMT

I'm trying to make a handle for a fireplace that resembles the handle on my fireplace at home. I used the polyline tool and filled it with a slab favorite. I've posted the result as an image so you can see. The edges are sharp, but I would like them rounded. Are there a way to do this?

You can get the rounding you want by making a complex profile
and using it to follow a path that is shaped like your handle or
you could use Profiler to do the same thing.

I've been trying to make a complex profile to the wall element. I've called it oval. It has a cross section that is 10 mm high and 15mm wide.
I made a handle with the polyline tool in the floorplan. That also has a cross-section of almost the same size. Then I use the magic wand to apply the wall-settings with the profile to the handle. The handle is not filled but I create some long walls. I suppose I have misunderstood the advice I got. I post the project so you can take a look if you like.
Thanks in advance.

Adjust your magic wand settings to "best match" and try again.

I tried to follow your advice, but the magic wand setting was set to best match already. But there are som settings that has to do with the length and the number of segments, as I understand it. I've tried to change it, but all I obtain is big circels around the "handle". When I try to select the circle, something in the handle is also selected. My "handle" is 110mm wide and 80mm high. The cross section is 15mm wide and 10mm high.

Anne,

Draw the centreline of the handle with the line tool on plan and magic wand that. It looks like you have drawn the outline.

The oval complex profile should be centred on the origin when you set it up for this to work correctly.

Also, the magic wand settings should be set to segments along circles
and 36 segments is OK.

I'm not sure how a complex profiled wall would be able to generate the tapered ends to the handle, shown in the zoom of your original screenshot here...

... but Cigraph's ArchiForma add-on lets you extrude any shape and then round the edges with the rounding panel (screenshot from PDF manual - not quite identical to the panel seen for rounding an extrusion).

ArchiForma lets you do most things that can be done with GDL primitives, such as this rounding. You might be interested in downloading the user manual to see:

And, maybe the demo version will work long enough just to create your handle. 😉

Cheers,

There's a trick.

To get a complex profile extrusion to "taper" requires wrapping the section back on itself slightly by using a tiny radius.

But, you cannot get an arbitrary taper, can you?

Attached is magic wanded spline handle thingy in ArchiForma with rounded top edges (bottom could be rounded too). Jaggy is just the magic wand settings used.

If the thingie has a planar top and bottom, then I think he could also do it with the slab he had at the start + a half round/ellipse/oval complex profile for the edge going all around, and saving the whole thing as an object.

Also since 11 I think profiled walls can be applied to curved walls, right?, so a curved wall may look better than a polygonal magic wanded wall and exactly match the curved sides in the slab. I don't remember if that is what you get with 'best match'.

I understand that this is far to advanced for a beginner like me.
I tried to do the first advice, but no success.
I will look into the ArchiForma information, later. So thanks for the links.
I think I'll return to the beginners manual for Archicad, to learn all the easy stuff. And, then I hope I will get a chance to become more advanced in a more slow speed.
But thanks to everyone that has tried to help me.

Hi Anne,
You could try this variation (created by Daniele Raggi) of the GS slab accessory.
I think it could do the job.
