Pulling Sheet Blocks to Solid Blocks (With Associations)

To mesh thin parts where features on top and bottom may vary slightly, you can do the following:

Generate a shell mesh on the top faces (ignoring or capturing features as desired).
Select the Pull tool from the Edit group.
Select the block face, or block faces to be extruded.
Note: You cannot pull only some faces of a sheet blocking to solid blocking. A blocking must be either entirely sheet blocks or entirely solid blocks, so when pulling sheets to solids, make sure all sheets in the blocking are pulled.
Leave Snap associated vertices enabled so that the software can find the appropriate faces to associate the blocks to.
Select the Up To tool guide and select the reference face to pull up to. New mapped or swept block(s) are created.
Note: You only need to select one face to pull up to. The software gets the pull distance from the selected face. The extruded block faces are then associated to the nearest geometry (so it can handle some deviation in thickness).
