I have to model Double Hopper Windows where the lower half is frosted opaque glazing, with the upper lite being clear glazing. How do I do this?

Opaque doesn't mean frosted, it means that light cannot pass through it. If it's just frosted the same amount of light is transmitted and you model the whole window the same as single glazed clear. 106 When I click on a node and move it the node will not release from the curser in the new position and continues to drag around the screen.

I then have to drag the curser to the delete zone icon to delete the zone and release the curser. That's because there is a problem with overlapping with another zone or something else that the program doesn't like. The status bar will tell you what the problem is.

Hitting the escape key or clicking on the "release tie with node" button will release the node and allow you to fix the problem. 105 I have examined the temperature profile charts. Several downward spikes occur which are too sharp (up & down) to indicate actions or building response.

What does this mean, and how do I explain these to the client? Fluctuations can be due to heating and ... more.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
