FAQ > SelfCAD Editor

I noticed that SelfCAD supports transparent objects. Does that mean I print transparent 3D objects?

Transparency is only for rendering; so, no, you cannot print transparent objects. 3D objects will be printed as a solid object, regardless of the opacity setting used during the design process.

How can I make my object smoother?

Try using the ‘Round Corners’ function to smooth out the entire shape, or use ‘Bevel Edges’ or ‘Smooth Brush’ to smooth out parts of the object. For solely visual purposes, try using 'Smooth' from Scene panel. Check out this video to learn more.

What units does SelfCAD use? What will the size of the final print be?

1 SelfCAD unit = 1 mm when the object is sliced and printed. 

You can watch this video tutorial to learn more about the measurement tool.

 

 
How do I select/unselect an object?

To select/unselect an object, click on it with your left mouse button. To select all objects simultaneously, click ‘Edit’ and choose 'Select All'. To select multiple things, either click on them one by one or right-click and drag(only works if you are using Firefox or Chrome).To unselect all objects, click anywhere but the objects on your workspace Check out the video tutorial on youtube to learn more about selecting and scaling objects in SelfCAD. 

 
Can I set custom hotkeys?

We are working on this feature and will add it very soon!

How do I zoom? How do I move the camera?

To zoom in and out: Switch to camera zoom mode (located in the camera function’s top panel). You can then use your mouse’s scroll toggle, use your laptop’s trackpad (move two fingers up and down), or the + and - keys on your keyboard to zoom in and out. To move/pan camera: Switch to camera pan mode (located in the camera function’s top panel). You can then press down scroll on your mouse and move the mouse (if available) or simply use the top/bottom/left/right keys on your keyboard to pan. See this video tutorial to learn m

How to Create a hole in an object in SelfCAD

Use the Difference option of the stitch and scoop tool. You can watch this video to learn more. 

 
How can I export my models in SelfCAD?

a) Find 'Export' in 'Files' then choose the format of the model you would like to export your design in.

You can choose to export your object in STL, PNG or:

  • .dae
  • .x
  • .stp
  • .obj
  • .ply
  • .plly(binary)
  • .3ds
  • .gltf
  • .glb(binary)
  • .gltf v2
  • .gltf v2 (binary)
  • .x3d
  • .fbx(binary)
  • .fbx

b) What happens if I try to export two or more objects at the same time?

What should happen is: you'll get a zip file with an stl or the extension you chose of every object you exported. 

If you want to export your group as one object, you need to Group them. There's however a danger that this will merge them, once you import them in another 3D modeling program.

 

How to use 'Cut with Profile'?

To use Cut with Profile you have to select both a mesh and profile which is drawn on this mesh and then choose Cut with Profile.

How can I hollow out an object?

To hollow out your object you can use Stitch&Scoop, select the polygons and delete them (all our 3D shapes are empty inside) or 'Flatten' the object then use 'Inflate'. Click here for a helpful step-by-step guide.

What is the difference between the Extrusion and Add thickness tools of SelfCAD?

Both tools are used in converting polygons into 3D models but the difference is the extrusion tool creates a surface model (shape design) where’s add thickness creates a solid model (geometric description of the model). See this video to learn more.

When I change UV settings of one texture, the other textures change too

Please check if the objects are grouped Group is considered as one object hence UVs are changing for all its parts.

How to add text to a 3D model in SelfCAD?

There are two methods: either by using the Text tool in 3D Sketch or in the FreeHand in Drawing. We would recommend using FreeHand for the best result. Just go to the Drawing -> FreeHand and choose Text, write your text, and confirm the changes. Now you can scale it, put it on your model and Merge, Group, or use Union to attach it to your model.

What is '3D Print' feature about?

3D Print gives you access to SelfCAD's slicer. 

The first thing you will see after clicking 3D Print is the preview, where you can see the results of your operations. In the top part of the preview, there is one of the most important buttons in slicer - Slice. Only after pressing this button the object is sliced into layers and only then you can see how the object will look like, what the path of the nozzle will be, how long the printing process will take.

Navigation is a little bit different than in the SelfCAD app - you also rotate the camera using the left mouse button, zoom in and out with the mouse wheel, but to pan, you have to use the right mouse button instead of the middle one. You can also reset the camera by pressing the button in the bottom left corner.

a) What will happen if I put more than one object in the slicer?

The Slicer will ask you it should treat the objects as separate or not. 

b) What if I can't find my printer in the Slicer?

You can create your own printer profile by pressing the 'Open Profile Editor' button. You can set all default parameters of your printer and material you use there.

c) Can I save the GCode?

After pressing Slice you can save the GCode, a file that provides information about the object being printed to the printer. When your object is sliced, the new button appears in the bottom right corner.  The white text "Save GCode" on it suggests that it is this button that generates the file, which should be delivered to the printer.

d) What do I need to do to print my model?

To print your model you have to do 3 things: import the object into the slicer, slice it and save the GCode which says the printer what it should do. 

To see SelfCAD's slicer in action, watch this video.

Can I export my models?

To download your models, you can click on File>export then choose. Though the free account doesn’t allow one to download the models, you can save it to the cloud or on Myminifactory. Watch this video to learn more about how to download your designs. 

 
Can you move/scale/rotate selected edges/vertices/faces?

Sure! Select edges/vertices/faces using ‘Polygon Selection’ and then use the desired transformations in the same way you would use them for shapes. 

You can check out this article to learn more.

 

 
How do I use a trackpad to control the camera?

Click and drag to rotate the camera. Using two fingers with the correct technique, you can also move the camera up and down and zoom in and out. Try using the rotation cube to easily get certain angle views.

Can I texture an object in SelfCAD?

Yes! Select your object and click at 'Material', between 'Color' and 'Opacity'. You'll find a selection of default textures there and an option to import your own. 

Please see this video to learn more.

 

 
I want to import an XYZ object but SelfCAD does not support it. Can SelfCAD add support for the XYZ files format?

Currently, we support only the most common file formats: STL (binary and text format), MTL, PLY, DAE, and SVG. We plan to add support for additional file formats soon, of a series of plugins.

Where can I get more advanced shapes?

SelfCAD users can access the MyMiniFactory library, which consists of over 30,000 ready-to-print objects. Simply download the object you want from MyMiniFactory within the SelfCAD application (you will need a separate MyMiniFactory account). You have access to thousands of amazing objects without having to create them from scratch. 

You can check out this video to learn more.

 
What is a 'Profile'?

In SelfCAD we have two types of objects - meshes and profiles. The basic difference between them is that meshes are composed of polygons and profiles are actually sets of edges. It means that the profiles have no volume and you cannot print them but you can use them to model many interesting printable meshes.

a) How can I create a Profile?

You can create profiles either by drawing them yourself in 3D Sketch or since each profile is composed of edges, you can easily copy them from the already ready mesh.

How can I create 3D text?

SelfCAD's 3D Drawing tool allows you to draw/type 3D text on planes and shapes. Simply click on the plane, or shape you would like to draw on and select the drawing tool. You will notice an option for adding and customizing text.

How can I save my 3D Objects in the cloud?

Besides downloading, exporting, and sharing your models on Social Media, there are three additional ways to save your 3d objects to the cloud in SelfCAD. Each of those methods has its own use-cases, and each of them will be introduced in the following paragraphs.

 

1. The first option is the traditional ‘Save’ found in the User Options. It saves the latest version of the project, with all of the settings and objects to the cloud. SelfCAD performs an autosave every three minutes, but you can click on the highlighted icon to save at any time, especially if you want to exit the project.

 

2. The second option is ‘Save Project As’. This method creates a copy of the entire project. It gives you a backup version of the project you can always fall back on, that you can access from the project page.

 

3. The third option is called ‘Save Objects’, which allows you to save a version of a selected model in the cloud, which can be used to create an object library. It’s particularly useful when you want to reuse an object in different projects because you can Load Objects from any scene.
