Submodels, mpd, and Lpub3D

[David Manley]

<snip>
I want to build submodel 1, 2, and 3 and then show how they go together. Then I want to build submodel 4 and attach it to the growing assembly, then submodel 5 and 6 and attach them to the main model. Build submodels 7-10 and show them being attached. Submodels 11 and 12 get built directly onto the main model. There are 4 copies of submodel 13, then attach them, finally submodel 14 goes in place and then gets rotated a bit.

One way to tackle this is to have multiple sub-levels of sub-models. You create your 13 individual "bottom-most" sub-models and then combine them to form another sub-model. For example;

Your top-level model would be defined as:
  Sub-model [A]
    Which is created as the combination of [1], [2] and [3]
  (Insert a "STEP" command here).
  Add [4]
  (Insert a "STEP" command here).
  Add [5]
  Add [6]
  (Insert a "STEP" command here).
  Add [7]
  Add [8]
  Add [9]
  Add [10]
  (Insert a "STEP" command here).
  Add [11]
  Add [12]
  (Insert a "STEP" command here).

  Add [13] #1
  (Insert a "STEP" command here).
  Add [13] #2
  (Insert a "STEP" command here).
  Add [13] #3
  (Insert a "STEP" command here).
  Add [13] #4
  (Insert a "ROTSTEP" command here).

N.B. you may find this easier to do the above using LDCAD. LDCAD offers an interactive 3D model perspective, part snapping and integration with the STEP command which (in my view) are easier to do with LDCAD than with MLCAD.
