Sorry this doesn't have anything to do with your question. but how do you add these drawings to your posts.

welllllllll......

first go to photobucket

http://photobucket.com/

set up an account and see if you can upload some images (my drawings were scanned into jpeg files here in the office)

if and when you get an image uploaded to photobucket, you will see three lines of code under the image (url, tag, img)

if you want to put the image into this forum, copy the IMG line and paste it into your post. Don't use the buttons below, just paste the IMG line from photobucket into your post.

here's an angle of the skateboard park pavillion Joe mentioned, just for the heck of it......

Ta very much.

Mark, if you are up for a challenge here’s a cool idea. If the structure you want is a “clamshell” what about making it elliptic or circular in plumb section or elevation as well as in plan?
I think it can be done: browse these Groin Vault Mathematics pages. The intersecting barrels of the groin vault form elliptic “Valleys”; the clamshell is the “Hip” version. (Hips, Valleys, who cares? Same thing).
I think I’ve got the geometry , algebra and trig down pat … but have never had the opportunity to try this out in the real world … whatcha think? How's your spirit of adventure?

I like adventure. I'm trying to digest the pages linked to your post, and I question that I would have the mental and actual tools to layout something like that... I think that the elipse could be the right shape for acoustics and projection, but to build it...? Maybe I should start organizing a guild rendezvous here?

Another issue that this building will have to overcome is the upcoming municipal election. The reeve in the madoc municipality will have to be re-elected in november.

Thanks so much for responding to this post, Joe. -I really will have to drive up and visit next time I'm in Madoc.

I'd like to take a shot at some 3d design drawings if you are interested.

well, the reeve did not get elected, but did stay on as reeve, since he ran unopposed. looks like the project may go ahead after all.

pegs_1 let me know shat you need to make those 3D's????
