Can be found right on spudfiles.
Go to "other" in the right top, and then pipe info.

Is a 3D drawing not made with 2D drawings from different perspectives?

No, 2D drawings are cut-throughs or side-views from 3D models.

Its just that sometimes, with complex structured units, it may be hard to view that in 2D. ie: when there are multiple things behind eachother.
Ofcourse, you can make several drawings from several perspectives, but instead you could make a 3D model and just screenshot all perspectives you need OR even send/show the 3D file so that the people you are showing it to will be able to pick their own perspectives.


And as I said, google sketchup is not an heavy 3D rendering program that takes alot of time, its just a light and simple tool which allows you to QUICKLY create shapes and objects. Its like paint, but then in 3D

i printed all the pvc size info from this forum. i meant a file with premade parts for sketchup.

The thing is, nobody is going to want to do this.

Here's a suggestion: whenever you decide to model a cannon, make all the parts as components, save them, and when you have gathered up a few, submit them.

i have 14 years of drawing board experience and almost 3 years of AutoCAD. i just think designs out in my head (combustions so far) and run B:C ratios on a simple calculator.

i got my first sprinkler valve a few days ago, so i will begin my first pneumatic design soon. i may go with 2-3 air chambers, in a folded design with a multi-piece barrel (i have a smart car, not much room to cart things around, length-wise), but i will sketch it out on paper, going to menards/home depot to size out fittings.

Ill do it when i find the time....... plumbing parts arent too much of a hassle in sketchup....

Hey i was reading the thread and i made a silencer/suppressor type thing for my pellet gun.

just a little example. took me about 20 min



based off another silencer i recently saw here at spudfiles

pretty schweet!

Great drawings too. Looks like you did your reasearch.

Very nice. I like your use of pipe.


I'd like to try to use it to model my more mechanically inclined projects, but before any of that, I have a few ammo ideas I'd like to try out for myself. Compacting flour in a tube, anyone?

I'll just leave this here.

flour it cheaper but talc (baby powder) is much better. it gives a better smoke effect. flower is too moist and clumps. so if u compact it it will try to stay that way.

i used talc in an airsoft grenade. if the powder got on u in the blast then u were out. it's also easier to clean up and off clothes. flour is way too messy and heavy.

Flour's okay for high-energy impacts. We used to use flour bombs on our R/C planes to find where they crashed.

Mark, did you make that with sketchup?

Yes.

I also finished a better model, as well. I made everything as components so that people who are interested can dissect it and use the parts in their models.

Howd you get the background Black like that? it looks more CADish......

Just some tricky Paint business.

i.e. - paint bucket.
