feature previews using temporary bodies

Hello,

is a long time that I would like to develop within my addin enables you to create previews of features with a temporary body.

My preview of features you must hook to the mouse movement and position in my face every click, a little what happens in a place HoleWizard.

I watched the post

and that's what I would do, but I do not know what to make it in writing, and in that event.

Would you have some examples of where I can work? My target is create for example a hole D10 depth of 30 mm.

I believe that the creation of temporary feature is a useful thing at all.

Thank you very much

Roberto
