Todetails assembly each other which need highly accurate level, we cannot draw two or more separate details without the standard one, the detail is designed basing on standard spline and size to limit mistakes as well as help design more quickly and edit fewer when two details have not same spline and size
For example: to assemble this detail we do as:
Step 1: Design a same form detail and insert to assembly environment
Step 2: In assembly environment, we choose Insert Components => New Part.
This selection means that we create directly a new detail in assembly environment instead of previous Part environment
Step 3: Click face needing to create Sketch
The Blue detail shows that it is being edited; above side also appear full modules as in Part environment that helps you design immediately a detail basing on shape and size of detail which is being assembled.
Step 4: Offset out spline is smaller than 0.2mm in order that when assembly has yawn, detail inserts lighter.
Step 5: Select Extruded to extrude cover’s thickness
As same as Extruded in Part environment, you do extrude spline to a surface, in detail is cover plane is coplanar with cover’s top plane
Step 6: Click “Ok” we achieve a result
