Hi All

I am creating custom light fixtures and many have a domed shade.  I actually used two bowls in the CA library for one of the shades (one for outer color, one for inner color) but was wondering how I could use the included shapes to do this as well or just CAD objects.  There is a half sphere available but I want to hollow it out.  Is there a way to "subtract" a smaller half sphere within a larger half sphere (create a hole?) to do this?  Some of the domes are not completely spherical, so I would like to edit their shape a little and then hollow them out.  Trying to do something like the sconce pasted in here.

 

I also attach a CA plan with the light fixture I created using the bowls (I don't know how to export one user object separately....)

Thanks

melissa

Select the object in the Library, right click and choose Export Library.

You can do what you need with Solid Modeling Tools.  It will be a bit slow at first until you get the hang of it.

 

The bowls or lamp shades can be done effectively using the Revolve Object tool.  Just draw a polyline that represents half of the section view and snap a face to it and revolve.  Also helps to locate and model about the 0,0 point so calculations are not required for the dbx.

For bowl like shapes, you can use a molding profile.

I think you mean making a symbol right ?   from your plan you take a 3D view , then Tools>Convert to Symbol>Electrical+advanced Options...mounts to ceiling etc.

 

Here is your Lamp back as a Symbol so you can check it out (Plan below) ...... and a better explanation in this Tutorial on how to do it....

this is the technique to subtract one solid from another to :

HOLY COW!  This is like Chief Architect PLUS Sudoku.  This is going to be fun!  The subtraction thing is awesome!  And trying to figure out the chamfer (new word for me!) object will be like a puzzle, of which I am a huge fan.

 

Thanks to everyone AGAIN for the help and pointing to the help articles.  And I was able to export an individual object, it just says "Export Library" and I didn't know it would do just the one I highlighted.

In my search for faces and revolving, I found this rather comical video:

Using everyone's help made the sconce.  Not perfect but good enough...

 

Having this software is driving my builder nuts but I don't care.... it is too cool

      I am using x-7 Upgraded from six and somehow lost the 3-d shapes form my; library( ie the ball  the box the wedge etc. and want them back...)
      Not found in the core library. Any thoughts?

      Can someone tell me how to create an interior dividing wall that starts at ceiling height but slopes (curves like a ramp) down to a half wall?  I can create a wall with a straight slope using a wedge shape sitting on top of a half wall but I want there to be a curve to the slope.  See image below.  THanks for any help!!  I'm using Home Designer Interiors 2016 on a mac laptop.

      This is not an extended video, just to show the extent we can create ecomplex roof geometries using chief. This is an example like the VW one johnny shared here.
