3D Shell - Board Outline
EasyEDA Pro supports simple 3D shell design, allowing users to quickly draw and create a simple shell.
If the simple 3D shell designed by EasyEDA Pro does not meet the needs, when exporting the 3D shell, choose to export the STEP or OBJ format, and continue the design in other professional 3D design tools.
To design a 3D shell, you need to draw the Board Outline of the 3D shell first.
Entry: Top Menu - Place - 3D Shell - Board Outline:
Drawn primitives are automatically switched to the 3D Shell-Board Outline layer:
Click the "3D Shell-Board Outline" primitive to set its properties in the property panel on the right:
After drawing, you can go to: Top Menu - View - 3D Shell Preview to perform a synchronous preview, and the parameters related to the 3D shell modified by the PCB will be updated to the 3D preview synchronously. The 3D shell preview will open in a new separate window.
Property description: Type: Upper and lower shell, push cover. EasyEDA Pro provides two housing types, and temporarily only the rectangular housing frame supports push-to-cover. 
Layer: Like other lines, you can switch to other layers. After the layer is switched, the type will change accordingly.
Push cover direction: When the cover is pushed, the direction of the cover is pushed. 
Overall height of shell: The overall height of the enclosure. For example, the height of the combined upper and lower shells.
PCB Height From The Bottom Surface of Shell: The height from the PCB board to the bottom casing surface is used to determine the flying height of the PCB.
Height of lower shell: The height of the lower shell. The height of the upper shell is automatically calculated based on the overall height.
Shell Thickness: The thickness of the case. It is recommended to be greater than or equal to 1.5mm, otherwise it is easy to break when manufactured with different materials and sizes. For details, you can check the process requirements of JLCPCB: https://jlcpcb.com/3d-printing
Top Inner Height: The height of the alignment groove on the inner wall of the upper shell.
