You can add ceiling lights in 2D mode (middle button with lamp icon in the 3 button set), or in 3D, its up to you. The easiest way is in 2D, you just drag a light from the shelf to the plan and it will be positioned at the default ceiling height.
@monica - Please check that the snap is turned on for the item you are rotating. Snap is on the top mini toolbar. The snap is at 45 degrees angle increments.
The tutorial video definitely has sound - please check that your sound is not muted and the headphone (if you are using any) are plugged all the way in. You can watch the same video on www.tapglance.com/tutorials
You can change the ceiling height in the layout screen --> Floors button --> Double headed arrow.
You can also use cathedral, vaulted, and sloped ceiling types.
For both of these features, please see our facebook page - www.facebook.com/tapglance
One of the first video posts is exactly about how to raise a ceiling and how to create a cathedral ceiling like in the image attached.
Thank you for your suggestions. As a result of your feedback, we have decided to implement a ceiling material feature in TapGlance, possibly in next update (1.01) and definitely by update 1.1.
I would also like to be able to work on different colors/materials for the ceiling. They are a critical visual component of most of our rooms.
I also would be like to be able to decorate the ceiling by changing colors, adding beams etc. I am currently re-modelling my living room and i wanted to do it in Interior Designer. I want to do beamed ceilings (which I can't), therfore I can't really complete my design ideas for this room at least accurately.
