First off- I would like to thank all of the mappers on this forum who selflessly help mapping n00bs like myself. Thank you for all of your time 
Ok; on to my questions.
I’ve been trying to learn about making maps for a long time- probobly reading 50 tutorials along the way. I’m currently working on a map that pretty simple- allies break into castle and blow up something (I havn’t decided what yet :???: ) and that’s pretty much it. I’ve very comfortable with working with brushes, as well as texturing and basic entities (lights, spawn points, MG42s, explodable-object etc.), but beyond that I gets very blurry. The one thing that’s really frustrating me is the dynomitable objective. I’ve tried it 8 times from 3 different tutorials, but it never works. Each time it doesn’t show the dynomite icon (it shows the hand icon to show that it can be destroyed), and in the command map it shows an icon of a Command Post. My dinomitable object it several brushes- is that a problem? Also- I havn’t been able to figure out how to make constructable things. I’ve read all over the place, but I can’t find anything that I can use.
Help plz :drink:

but while I have your attention- how do I add a model? Every time I try misc_model and select a model it just shows up in the editor as a wierd box thing with lines through it…
