FAQ > SelfCAD Editor
I am trying to download/export a few objects, and nothing happens after I click ‘Export as an STL’. Am I doing something wrong?

Most likely your browser is blocking the downloading of multiple files. Please check your browser settings.

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.

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

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

How do I select/unselect an object?

To select/unselect an object, left click on it with your mouse or select/unselect it in the ‘Scene Panel’. To select all objects simultaneously, click ‘Edit’ and select the appropriate option from the drop-down menu. To unselect all objects, click anywhere on your workspace.

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.

What is the difference between `Union` and `Merge objects`?

Union cuts the polygons to make it watertight objects (removing inner faces and stitching at intersection). Merge objects is only combining and removing duplicated vertices (without any clipping operations).

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.

Can I download my objects or save them on my device?

Yes. You can download your objects in stl format or save them on a local device by updating the saving settings in ‘Preferences’. We recommend saving your design on our cloud-based server to ensure your designs are safe and always available wherever you happen to access SelfCAD.

I got lost in the scene. How do I reset the camera?

Click the ‘Reset Camera’ icon (located in the camera function’s top panel) or press Ctrl + 0.

Can I export my models?

Yes. You can download your 3D models as an STL file. To download an object, go to File - Download - Download as STL.

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.

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.

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.

How can I create 3D text?

Our 3D drawing tool allows you to draw/type 3D text on planes and on 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 text.
