PVC and Plumbing Design Software for DIYers

Design PVC and plumbing projects in 3D with fittings from 1/2 to 4 inches, plus steel and brass parts on the same threads. Get a complete parts list.

How it works

From idea to parts list in three steps

  1. 01

    Lay out the pipe run

    Click an open end and pick the next fitting from parts that actually fit that size and connection type: slip, threaded or socket.

    Watch the demo
  2. 02

    Check the parts list and cut plan

    Every pipe length, elbow, tee and adapter is counted as you build, and the cut plan shows how many 10 ft sticks of pipe to buy.

    Watch the demo
  3. 03

    Fill your cart

    Match each fitting to a store product and fill your cart at McMaster-Carr, The Home Depot or Lowe's, then review it before you check out.

What Connects to What?

What Connects to What? demo

Click an open end on a pipe or fitting and the parts drawer opens with compatible options, such as the next elbow or length of pipe. Pick one to attach it at that joint. On PVC pipe projects, the next part comes from the joint that needs it, not a long catalog hunt.

Snap-to-Connect

Snap-to-Connect demo

Bring a loose part close to a supported connection point and it seats into place, lined up with the rest of your build. Snapping takes the fiddly guesswork out of joining uprights, rails and other members, so each piece meets its neighbour at the connection itself rather than just floating nearby.

What Parts Do I Need?

What Parts Do I Need? demo

Every board, pipe and fitting you add shows up in a parts list beside your 3D model, with quantities that update as the design changes. Hover a row to find those parts in the scene, then check the counts before you cut or shop. Your design becomes a list you can review line by line.

Get Your Cut Plan

Find out how many stock lengths your project needs before you buy. Choose a stock length and see your finished pieces laid out along each length, with the leftover shown. Your parts list becomes a simple cut list, so you can plan the trip to the lumber yard with fewer surprises.

Fill Up My Cart!

Fill Up My Cart! demo

Once your design is ready, match each line on your parts list to a store product, check purchase quantities and skip anything you already own. When you are signed in, Crafti fills that retailer's cart for you to review before checkout. You skip retyping every part by hand, and nothing is bought until you decide.

Design from an Idea, Text or Picture

Design from an Idea, Text or Picture demo

Describe what you want to build, or attach a photo or sketch, and Crafti AI drafts a whole design made of separate parts you can edit. Start a raised garden bed or potting bench from a sentence, then select any piece to keep refining it. Your project begins from an idea, not a blank screen.

Instant Assembly Guides

Instant Assembly Guides demo

See how your project goes together, one numbered step at a time. Each step names the parts to join, marks where they connect, and shows that subassembly within the whole build. It turns a finished 3D model into clear woodworking plans you can review before you head to the shop.

Massive Library of Real Parts

Are the PVC Parts Compatible?

PVC parts can seem like they are compatible when you're at the store buying them but then you realize that the PVC fittings don't quite work... that you maybe bought CPVC instead PVC?

When you get your parts list from Crafti, you can be sure the PVC tubing from PVC elbows, PVC pipes to a PVC corner tee and more parts are compatible when snapped together!

Easy to Work With!

PVC is a great material to work with because it's easy to cut and glue! You can easily cut all the PVC pipes with a basic hand saw or a ratcheting pipe cutter. Gluing with PVC cement is also very easy and once it glues, it hold super strong!

PVC is not only great for plumbing, you can also build smart DIY PVC projects like PVC pipe desks or bike racks. Since it has a great variety of parts you will only need a PVC coupling, a PVC cap, pipes, adapters and cement we can assure you your creativity will have no limits.

Not a Plumber? No Problem


It's intimidating to see all these PVC parts and not know what you need. However, once you make your first design, or edit a pre-designed project you'll start to difference a PVC union from PVC adapters or PVC Plugs.

You can always order or play with someone else's PVC design project to get started. Once you get to know the parts a bit more, you'll start to wrap your head around all the PVC material very quickly!

We have a lot of PVC pipe projects pre-designed from a PVC dog wheelchair to a ram pump. Easy or complex, depending on your building experience.

You'll soon be using a 4" PVC double wye or naming each PVC adapter knowing exactly how they work. The real challenge is to start!

We Know What Fits Into What

We know the size & type of each connection of each PVC part So we show you only compatible parts when you're designing your DIY projects

PVC and plumbing

Why PVC?

PVC was designed primarily for plumbing but many people realized it was a cheap / easy to use material for making lots of things! People have made table, chairs, carts and geodesic domes! The other very cool thing is that the connections for PVC are also compatible with steel as well so you can combine the PVC tubes.

It's also known for its durability and long lifespan resisting weathering, chemical corrosion, and abrasion, making it suitable for outdoor or indoor. PVC parts also tend to be very affordable so you can buy extra parts / play with them without feeling like you're going to waste a lot of money. PVC tubes are hollow inside so they aren't great for any weight bearing designs unless the length of the tube is very short and supported with a strong structure design. You'll find PVC fittings, elbows, tees, couplings, caps, crosses, adapters and so many other compatible parts to make your free designs and just explore your ideas.

Fill Your Cart in One Click

Once your design is ready, Crafti matches every PVC part on your list to a store product and fills your cart at McMaster-Carr, The Home Depot or Lowe's. You review it before checkout, and nothing is bought until you decide.

Questions

PVC and plumbing design questions

Will Crafti tell me if two fittings don't fit?

Yes. Each fitting knows its size and connection type, so when you add to an open end you only see parts that fit it, including the adapters you need to change size or material.

Can I mix PVC with metal pipe?

Yes. The library includes threaded adapters and copper, brass and black steel fittings, so you can plan a transition from PVC to metal in the same design.

Which sizes are included?

Common PVC sizes from 1/2" to 4", in Schedule 40, Schedule 80 and DWV, plus CPVC Schedule 80.

Is this a downloadable app?

No! It all works on the browser. It works on your phone as well as your computer!

Can I save my design?

Yes! You can save your design in your account.

Can I share my design?

Yes! You'll have a unique URL for every design you save which you can send to anyone! They can then see or clone the design. They cannot edit your design. You can also delete it whenever you'd like.

What materials do you support?

Crafti has 7,300+ parts across aluminum 8020, steel, wood, HVAC and PVC! Let us know if we're missing a part.

Where did the idea for this app come from?

I spent a year building an off grid farm and knew nothing about construction / plumbing / electrical work…
I saw that most people had to go the hardware store multiple times and many times they weren’t able to finish their work that day because the vendor didn’t have the part. So I thought if you can design your project beforehand, it will allow us to check for compatibility while you’re designing and then fill your cart at the store with everything you need! Much easier!

Can I connect PVC to wood, t-slot / aluminum 8020?

Yes. There are transition parts that allow you to connect PVC to wood or wood to aluminum 8020. If there is interest, we will start adding parts like motors and electrical components as well.

The idea for Crafti is to be a place where you can design your entire project with all of its components so when you want to get to building, all you need to do is review your cart and check out!

Can I buy the parts through Crafti?

Crafti doesn't sell parts itself. When your design is ready, it fills your cart at McMaster-Carr, The Home Depot or Lowe's so you can review everything before you check out.

How do you deal with long and heavy parts (like 2x4s)?

When you have parts longer than 36" or of a certain kind (like lumber beyond a certain WxH), we just give you the dimension / exact length for you to go buy that at your local store.

Are you going to add more parts?

Yes. We keep adding parts and features based on the feedback we get, so let us know what you need!

Why not just use CAD?

You can! If you have all the parts downloaded already and are an expert in CAD software. Also, I would hope that your CAD software gives you a clean output of all the parts / their exact measurements.
What CAD software won't do is allow you to share the design online and allow others to see your design and specs.

Do you have tips I can follow for different materials?
Do you have any tutorials on how to use the app?
Do I need Crafti Pro?

No. You can design for free, and many features work in the free version. Crafti Pro unlocks some features and includes monthly credits for Crafti AI. See Pricing for what it includes.
