Here you need to make sure the latest complete.zip is stored.

If you need non published parts available just copy/past those XX.dat files into the complete.zip file and restart LPub3D and voila the missing parts are visible and not anymore showing as ablack cube.

Step 1
Right mouse click just outside the image of the last step

Select the option “convert to Callout”

The full sub assembly with its 2 steps is now added like a callout. You can chose to leave the parts list per step or put the parts list at the top of the page

Step 2
Right click on the parts list and select “No Parts List per Callout”.

You see now that the total number of parts is moved to the page parts list. This is a way to reduce the number of pages of your building instruction or leave out the pages with just a small number of steps.

Step 3
Drag and drop the call out to position it in a better location.

Here we explain how to use the ‘Treat as Part’ function in LPub3D.

This is how you can create this behavior in MLcad.

1. BUFEXCHG STORE A
2. Brick(s)
3. BUFEXCHG STORE B
4. BUFEXCHG RETRIEVE A
5. !LPUB PART BEGIN IGN (old style, comment)
6. Brick(s) – flying in same as in STORE A
7. Arrow(s)
8. !LPUB PART END (old style, comment)
9. STEP
10. BUFEXCHG RETRIEVE B

With LPub3D this results in:

Alternative with one BufferExchange ‘nest’:

1. BUFEXCHG A STORE
2. Brick(s)
3. Arrow(s)
4. STEP
5. BUFEXCHG A RETRIEVE
6. !LPUB PART BEGIN IGN
7. Brick(s) – flying in same as in STORE A
8. !LPUB PART END

Here is how you can accomplish this in ldraw.org MLcad.

In MLcad create for the two sub assemblies to be ‘married’ different models. Menu option ‘Multipart’. For model 1 with the ‘Technic Pin Long with Stop bush’ create also a model without the these parts.

General step up in MLcad:

1. model 1: sub assembly one
2. CLEAR statement
3. !LPUB PART BEGIN IGN (comment, tickboxed); because all the parts are already in model 1 for Bill of Material.
4. model 1*: sub assembly one without the ‘Technic Pin Long with Stop bush’ (GHOST)
5. !LPUB PART END (comment, tickboxed)
6. model 2: sub assembly two
7. BUFEXCHG STORE A
8. !LPUB PART BEGIN IGN (comment, tickboxed) because all the parts are already in model 1 for Bill of Material.
9. (number of ..) ‘Technic Pin Long with Stop bush’ (GHOST); pins in final position.
10. BUFEXCHG STORE B
11. BUFEXCHG RETRIEVE A
12. (number of ..) ‘Technic Pin Long with Stop bush’ (GHOST); pins in extracted position.
13. Arrows
14. STEP
15. BUFEXCHG RETRIEVE B
16. !LPUB PART END (comment, tickboxed)

With LPub3D this will results in:

By using below commands in your MLcad you can have the complete universal joint in your parts list but show the bent universal joint in your building instruction.

Menu > Edit > Add > Comment or ‘ab|’ in quick access menu bar. . Following popup appears:

 where you fill in :

1. !LPUB PLI BEGIN SUB 61903.DAT 71
   1. 61903.DAT = the file number of the part you like to show up in your parts list
   2. 71 is the color from the color palet
   3. General: !LPUB PLI BEGIN SUB <part file> <color>
   4. CheckBox ‘Old style…’, checked
2. You repeat this for all other commands below.

!LPUB PLI BEGIN SUB 61903.DAT 71 – This part, complete universal joint 3L will show up in parts list and bill of material.
!LPUB PART BEGIN IGN
(parts replaced by first line part like universal connector)
Example:
62520.dat  Technic Universal Joint 3L End
62519.dat  Technic Universal Joint 3L Center
62520.dat  Technic Universal Joint 3L End
!LPUB PLI END
!LPUB PART END

This can also be applicable for:

1. Flexible axle; you draw your flexible axle with LSynth in a separate new model. With above you replace it by the right length part like ‘32199.dat Technic Axle Flexible 11’ (11 studs long)
2. Shock absorber
3. Pneumatic Cylinder

Main Question remains how to initiate those in MLcad. Here is how:

After running the Parts Install .exe or adding the parts from the Zip-file open MLcad

Go to: Menu item File and click ‘Scan Parts’, et voila!!
