Translations:Assembly3 Workbench/50/en

We omitted one important step that should be done in larger assemblies: locking a base part. That means define one part that should not be moved by constraints. In your case we use the cube for that: Done. If you like you can move the "Locked" constraint upwards in the tree. Use the "MoveItemUp" button on the Main Toolbar for that.
 * Create a new FreeCAD file
 * Select assembly WB. Select CreateAssembly (first icon)
 * Select Part WB and add a cylinder and a cube
 * Save the file with any filename you like. Close and open and the file.
 * The tree view should look like this
 * Now Draw&Drop with the mouse both Cylinder and Cube onto the Parts folder. They are moved into that folder.
 * That is the quickest way. Please note that a better way is to open the Context menu on both and select ContetxMenu/LinkActions/MakeLink. This adds two link files. Then Drag/Drop the link files to the Parts folder. For simple cases like this it does not really matter.
 * Click both top surfaces of Cylinder and Cube (keep Ctrl pressed)
 * Select assembly WB. Select "PlaceCoincident" from the Constraint Toolbar.
 * Now the parts should be joined into each other and your tree should look like this
 * Right click "_Element" (any of the two) and select "Flip Part".
 * Now the Cylinder should be on top of the box. If the whole thing is upside down, go back and select "Flip Part" on the other Element.
 * Right click "_Element" (any of the two) and select "Flip Part".
 * Now the Cylinder should be on top of the box. If the whole thing is upside down, go back and select "Flip Part" on the other Element.
 * Select the lower face of the cube. Only the lower face, not the whole cube.
 * select the "Lock" constraint from the constraint tool bar
 * The finished assembly tree should look like in the image above
