 How to do Top Down Assembly Modeling in ZW3D

Top-Down and Bottom-Up are the major assembly methods when doing assembly design. Most users know how to do Bottom-Up Assembly modeling as it is the most popular form of assembly modeling, however fewer fully understand Top-Down Assembly Modeling.

This topic will use to do detailed introduction in ZW3D to show how to do Top-Down Assembly Modeling, please reply your idea if you have more idea about this function.

Simple videos to show Top-Down and Bottom-up Assembly method in ZW3D

What is the Top Down Assembly Modeling?

In short, in the top down approach you have to create the blank assembly first and then you have to go on creating the sub-assemblies and parts in it. So, if the main assembly is at the top most level and the components are in bottom most level, then you are coming from top to bottom and it's top down assembly.

An excellent post.

Simple but critically important.

It's my opinion that every user of ZW3D should work through and fully understand this entire post (the 6 minute video helps a lot).

A complete understanding of this will make us better users and will contribute more to realizing just how powerful this software is.

I'm learning a lot watching videos and reading documents, and i'm also understanding that this Zw3D is more powerful than i was believing. Ooops, i still remember the days when it was simply called VX :)

Anyway, Top-down approach could generate too many dependencies, and this might become not easy at all to handle when the designer needs to reorder and "clean" all those parts. This is only my view, but i believe there is an important command still missing and very useful at the same time, i mean "convert to independent" any external reference, so we can "isolate" the current part and reuse it next time out of its project. Thats why i would like to see inside the sketch environment a window where i can see all the used references and, optionally, delete them or make independent, if not necessary.

Thanks.

Hi X (Forgive me so call you, since I didn't know your full name).
Thank you for your encourage and trust, I think the new feature call Link manager in ZW3D 2015 is the function what you need to manager the reference between different component during interpart modeling.

This new link manager will not just used to manager the references inside sketch, it will manager the all references for the all part.

I will invite you to test our Beta version next week, hope that you can give us more suggestions.

Thank you in advanced.

Hi xOR3D,
with appropriate skill, Z3 has always been able to easily convert to independent which for the reasons you say is often required.
But this is not a single part focused command as you suggest.
The table makes the process much easier - but the process of unlinking is the same effect no matter how it is done.

Cheers
