Woodwork Cad Template,Traditional Jointer Plane Quiz,Rt0701cx7 Canada Trust,Open Hardware Robot - Step 3
In the examples so far we looked at shapes that are square and based on precisely measured objects. You want to have a look at a different kind of software if you plan to get creative and work with organic, sculpted shapes. After creating a model we want to do something with it. If you designed something for the CNC you want to create gcode that the CNC can execute to cut out the shape you designed.
This is called CAM. For traditional furniture it is important to have a good drawing and ideally a cutlist that helps you to cut everything to the right dimension.
There is however an important difference. This could however change every day. Other solutions are open source software where you do not only get a CAD system but also the source code — so to say the assembly instructions for the software and you will always be able to use it.
In the following picture you can find a quick overview of the strengths and weaknesses of the solutions:. It is similar to Illustrator so you can draw simple shapes but also get very artistic and design organic shapes — such as the patterns for the living cell table design.
Besides templates Inkscape can also produce shapes for a a lasercutter or a CNC machine and it even includes a simple CAM solution that can create gcode. The only disadvantage of Inkscape is that it is not parametric and not able to easily produce measured drawings. If measured 2d drawings and parametric design are important for you you might want to look at LibreCAD. However when a project requires a parametric 2d shape you can create it also in a 3d CAD program.
The next software on our list is Blender. Blender is a super powerful 3D modeling and animation open source software. You can create entire short films in Blender and we use Blender to edit our videos. Blender is a perfect solution if you want to sculpt a model or if you want to modify a file before 3D printing it.
While it is excellent for creative modeling Blender is not parametric and while you can use it out of the box for traditional CAD work it is a bit cumbersome. While there are a few CAM addons for Blender none of them seems to be actively developed and maintained. For a long time Sketchup was our go-to solution for 3D modeling.
It is a great solution especially for complex assemblies with a lot of parts. Another great feature is that while the drawings are mediocre with an addon you can create a cutlist that is very handy for woodworking projects.
We stopped using Sketchup for a couple of reasons:. First the vendor of Sketchup, Trimble, offers the new version only on the web — which means that they can limit the access easily — in contrast to the old version that would run forever on your local computer. Secondly the ruby scripts such as the cutlist addon mentioned before no longer work in the web version.
You can still add drawings but the lack of the cutlist addon is really bad news for all woodworkers. Thirdly Sketchup is not parametric and the free version is missing some critical features such as Boolean operations that make it very hard to use it for single shape 3D printing models or any sculpting work.
The same is by the way true for Onshape. Which brings us to the next solution on the list: Fusion Fusion is perfect and comes with all the features you ever wanted.
It is parametric, has an easy user interface, allows for sculpting, creates CAM paths for your CNC and can create renderings as well as technical drawing. Now you might argue that it is pure paranoia. Why would a respected company such as Autodesk offer a solution for free, build up a community, invest in the product just to discontinue it or charge money for it?
The reason is pretty simple. They are driven by shareholder value. If you feel uncomfortable with putting all your eggs in one basket given that the rent for this basket might be a few hundred bucks going forward have a look at FreeCAD.
That means you can download and modify the source code of the software. Even if the website closes down you will always be able to use the software and adopt it to your needs. FreeCAD is still under heavy development but it comes with a fully parametric design system and is able to create gcode as well as technical drawings. While FreeCAD was at the publishing of this article a bit clumsy when it comes to multipart assemblies a lot has changed and I published a post on FreeCAD for woodworkers and a detailed instruction on multi-part assemblies.
It might be more difficult to get used to the software but for us the benefit of using an open source solution easily outweighs the more difficult learning curve. The last tool on the list is a bit of a niche solution. With OpenScad you create your model with a simple programming language. We mainly use it to create models that need complex parameters like these voronoi vent covers and to create parametric models for Thingiverse.
When we draw something we usually use Inkscape. We also use Inkscape to send designs directly to the vinyl cutter. For the laser cutter we only needs a free 2d CAD solution. When a lot of parts have to fit on a single sheet we use the open source software deepnest. When a 3D printed design such as this router jig needs to be configured with a lot of parameters we create it in OpenScad to make it easier for people to configure their own version on Thingiverse.
For creating or modifying STLs from Thingiverse or other sources Blender is the most convenient tool. It is easy to cut away part of the model, merge several models together or modify the mesh. We are not experts on the CNC and while using Fusion never managed to wrap our heads around the more complex options of adaptive paths and all the other advanced CAM features. For us this lack of features is actually an advantage as it means we have less possibilities to mess things up.
For woodworking and metalworking projects choosing the right free CAD solution is quite difficult. We did some models in Fusion and are missing the the possibility to create a cutlist.
FreeCAD has some possibilities to create a bill of material — which is a very good starting point to create a cutlist in another software such as cut micro. Arranging several parts in FreeCAD is either simple or parametric. Moving parts in FreeCAD is easy but these connections are not parametric. As soon as this feature is stable FreeCAD should be able to provide everything you need to model furniture.
Till then we will have to work with assembly options rather on the level of Sketchup than what Fusion is offering. This approach is described in this article. This was a quick overview of the free CAD software we are using. Are we missing something? What software do you use? Let us know in the comments. January 17, March 20, August 8, May 23, As woodworkers we are a small customer group. In the current version these lines start at line After switching to the A2plus workbench we can now import the individual parts one by one with the button that shows a plus sign.
These parts can be aligned with one another in a variety of ways. Just select two faces that you want to align, click on the plane coincidence button and decide if the two objects are opposed or aligned with one another. After aligning three faces a board is locked in place. Assembling a project this way is fast and actually quite fun. After everything is assembled we create a cutlist with the part list button.
If the dimensions are not listed please modify the A2plus workbench as described above. We import the cutlist in libreoffice so that it is easy to calculate square footage, price, weight and other data. You can also export the data to another software such as Cut List Optimizer, a free but not open source optimization program that helps you to optimize sheet good usage.
When we use hardware such as hinges or knobs for a project we add information about a part directly in the cad file. To do so just select the part info button from the assembly 2 plus workbench and you can add various information. All this information will at the end show up in the part list and makes cost calculations and ordering parts easy and convenient. Besides the cutlist a drawing is quite helpful when building the final piece.
In the TechDraw workbench we create a new drawing and are now free to insert different views. We can also select only part of the assembly as for example the lid and generate a drawing of only these elements. With a few clicks we change to the raytracing workbench, add a new povray project and add our objects to that rendering. In the following we describe how to use a different template file and how to fine tune the result so that it looks like this picture:.
Create a new cube withe the Part workbench, then switch to the Raytracing workbench and select the new WayofWood Template:. Next select the cube and the povray object and use the button with the yellow square to add the cube to the rendering:. When you now hit the blue rendering button you get already a nice white cube sitting on the floor:. Click the cube view object within the povray project not the one in the main part and select one of the colors that are shown in the color match PDF.
As an example we select magenta. Rendering the image again should result in a cube like this:. We can further improve this cube image by saving the povray file to the disk with this icon: to a file test. We open the command prompt go to the directory where the file is stored and type:. By using other colors in the file you can easily create other wood textures. These renderings are not perfect but the povray files offer you the possibility to tweak them in detail, change the textures or add additional objects.
Desining for woodworking with FreeCAD is not ideal. But for the assembly as for the rendering: The great advantage of an open source solution is that one can modify everything and add new features. Maybe you also give FreeCAD a try and let us know what you think about it. January 17, March 20, August 8, May 23, Great possibilities!
Thanks for your good work! Does this stuff work in 0. Because I try to use v. Save now? How could I get the proper Free Cad version, if the reason is version? How this kind of stuff could be possible in the real production — are there any recommendations? For the benefit of anyone else coming here to find where to download v0. Until it is officially released go to the downloads page. Click on the button.
Now in Github scroll down until you reach the 0. Look at the instructions about Click on the blue link with that title to be taken to the various releases — download the appropriate latest release for your operating system following the instructions given.
And thank you for the tutorial. I also now have a question. I shall post a question on the Forum and, failing a reply, will try the tutorial without them then try to work out where they should be included and retry it with them. Did you do a search in all your folders? Do you have other files in a A2p folder? If the workbench is working these files should be present in some kind of subfolder where the application data sits.
Hi Paul — I was having the same problem trying to find these files on Windows Hello, wayofwood again! Thanks to you and to all the people for the answers! Sorry for delayed answer…. Everything works fine. There was no need to correct any files or to install v. Can you provide them or tell me where to look? I just posted a detailed tutorial on the box assembly that also links to a zip file with all the files for the box.
Thank for the tutorial!!. Can your send an direct link to the post or part list? I will appreciate it. Hello, I have tried to render a object described by your workflow. However, i was not able to aply the Wood texture. The cmd. If you have Python and Povray installed the script should work.
There is a new Assembly 4 that seems to be taking its place. I am wondering what to do about that. I definitely want to make cut lists, and do assemblies.
