Step 1) Firstly a piece you want to add to another mesh you must first right click and copy the branch




Step 2) Now you right click selecting the mesh you want to add it to and bring up the menu and click on paste branch




Step 3) OMG It hasn't gone where I wanted it! This is why you right click on the added mesh and select Transform and then edit to bring up this menu:



Step 4) Ok, it's in place, Now we bring up the menu found in view and click on Block Details.




Step 5) Now we have the Block Details select up the top 0 Nilnode *insert mesh name* to get the Block Details we need and look down in this picture you will see I have selected the num children unit and it currently is set at 3. For each mesh part you add to the mesh you have to add it to this number.




Step 6) Now underneath you need to bring up the menu shown in this pic by right clicking and click on Update



Step 7) Now in doing so we click on the small drop down menu on this and after updating it we have a space to add our new mesh part



Step Ok We got the space, what do I add there? ( I ca hear you asking me and I will tell you ) You see in the picture I have selected the tristrips of the mesh we added. Well you always add the number of the tristrip of the mesh you add to a existing mesh.



Step 9) See I added the number and it automaticly writes the mesh in.



Step 10) Always before saving click on Spells and then select Optimise and clik on remove bogus nodes, This just ensures the mesh is all good. Then after doing this click on File and select save as and you are all done.






You don't have to do all the steps with each mesh you add but this is how you make new meshs. It's how I made the thrones. Sometimes a error will come up and it won't paste in the branch you want to add, I do not know how to fix that but likely someone knows how.
