I have them created in autocad, just have not uploaded to sketchup.

Trying to determine what lengths are optimal.

I have one at about 12 inches complete.

Probably next week!

Make just one that is an inch long. We can put them together from there to make the correct length.

Also, FYI, on your brass tees and crosses (here), I can't select just one image. All of them are selected as one unit.

Click on: "Edit", "Component", "Explode" then save the file.

I occasionally forget to explode the one component. (even though there is more than one part on the drawing)

You can explode any drawing and modify it. But always make as component afterwards.

Some of the complex drawings have several separate sections to make one component. For example the ASCO Valve.

Your wish has been granted sir!
You can join any of these combinations together to get up to a 30 post rail which is typically the maximum.

To determine rail length multiply post count times .394. Example: 30 x .394 = 11.82 inches.

We'll just have to wait and see.

Fellas, there is no reason why you guys shouldn't be using Sketchup. This program is so simple to learn and use. And dewey is just making it that much easier.

Agreed. He's been kicking ass left and right with sweet model creations. Sketchup designs are turning into a real treat.

Dewey, I may have missed them, but I only seem to have 1 inch and higher pvc fittings. I've also noticed that there are no street elbows in any of the pvc fittings.

Hubb;
I did not do 3/4 PVC or any sch 40 fiitings.

I will have to update all sch 80 fittings to include street elbow (sp x soc) or may be just add its own catagory. There are alot of other types of fittings I did not include.

I tried to get the most common fittings done first.

Latest addition to library.

If other CAD file format needed, just PM request.

Very nice. I like it. Would it take much to change a very small item and angle the pressure relief valve so it is perpendicular to the curve of the end instead of parallel to the tank centerline? No need to bother if it is difficult to rotate the part slightly. It is a minor detail.

The angle is 5 degrees for relief on this drawing.
It will not be all that noticeable. For your drawings it will have the angle.

Here is original for comparison.

I never noticed the shoulder under the relief valve. I took a look at my launcher and can see that there is indeed a flattened area for the relief valve. I never noticed it and assumed the valve was flush with the curve of the tank. It just looks bigger in the rendering. Nice job on the tank. Looks great.

@Tech;

My models are more realistic than your memory! :D :D :D

Where should I post the 1 inch QDV?

Do you want it in this posting and the sketchup library?
