Hi,

You're not entirely clear on what you're trying to achieve in all cases but I will try to advise. However I would recommend that you take the online training available on the Learn Server as this would cover most of these questions.

1. I believe you want to offset one duct to go above or below the one it would clash with. The key here is to turn ortho off or to 45deg or 30deg (Defaults > Ortho > OrthOFF) and to change the Duct height as you draw (Right Click > Duct Height). I created a short video to demonstrate.

2. Use the same method as above (Click on the duct where you want the branch, turn OrthoOFF, Change duct height, Click for next point of duct and continue drawing).

3. Depression down and Depression up are where the duct narrows in height from either the top or bottom to go under\over another duct. Offset Up and Offset down are the same as diverting the duct over another (as question 1). The key with these fittings is that you don't draw the offset\depression you just draw all the duct at the same height and add these fittings. It doesn't change how the duct appears in isometric but it adds an appropriate K value to account for pressure drop. You can manually draw a depression down\up bu using the technique shown in this Wiki.

4. A Diffuser will not connect directly to a plenum box. You need to include a short rising duct connection between the two using the Right Click > Duct Height method. I created this short video to demonstrate.
