Hi all,
I think abaut to make assembly without mates and to move components and assy in main assy only with "move component".
For my work there is not real need for components to be mated one with another and if there is, we mate only component plane with main plane (then there is again no mate between 2 components).
Has someone expirience with that or something similar ?
nice day

Almost all my assemblies are that way, unless I have multiple items then I need to mate them, even if I have left and right hand pcs.
What I do is save the main assembly and do a save as for as many sub-assemblies that I need and then use the Insert Components Dialog box and I can choose multiple sub-assemblies and when I insert the sub-assemblies, (or as you say sub-ass), I hover my mouse over the point of origin and click to drop in the additional assemblies. I do the same thing for all the parts, in other words I might save 10 or 40 part files and drop them in the same way, and when you do it that way everything shares the same point of origin. If I need to make a left hand part I open the right hand part select the Right Plane and select Insert Mirror Part and follow the prompts. When you do it that way all the parts come in fixed, but in context and if you use a Skeleton Sketch Part (SSP) as the connection between the multiple part they become parametric and change according to the changes that you make in the SSP. Doing it this way also allows you to change out any part without affecting anything, just delete the part and insert a new replacement part.....
At every assembly you need to have the SSP
I changed from english to german and i lose my tach to some things (ass-assy/sub-ass...).
We also will eventually start with a skeleton form but the company has changed to SW 3 months ago and there are other things that must be done first.
I hope i can get some more information and ideas and eventual problems that i should think of before starting and presenting that "no mate" idea.
We are making tent constructions from aluminium and steel thate have differences like length and width.
I think John Stoltzfus has a pdf with some details on the method (a quick search didn't turn it up). It is a completely different way of doing things than any of the SW help files or tutorials show you how to work. But, the benefit is that if you need to make a change at the end of the project, it is much easier and a lot more robust.
I learned just about everything I know about this method from John. I made a tutorial for something a little simpler than what he posted above at Skeleton Sketch Part Method for Large Assemblies using the methods he taught me. I tried to put everything I could think of in that PDF. For instance, using this method you will want to use "Isolate" all the time. I hardly ever used that tool until I started the SSP method.

Here is the PDF
What is your opinion if i fix components is it better than to full define the components from the performance stand?
I would say yes but i am not 100% sure.
I work now with a 24k(all components) main-assy with 650 sub-assy and components and i got loot performance problems.
If you are using 2018 they have greatly improved Performance Evaluation. Definitely look into using it. Just using that tool and changing 3 or 4 parts that were used many times in my assembly cut my open time from 3 or 4 minutes to less than 1 1/2 minutes. It will also help you with rebuild times.
For rebuild time:
Fixing all components < Fully Defined < partially defined
Fixing Components gives you a faster rebuild time than Fully defined with mates. However, You sacrifice the intelligence in the assembly. Unless you are adding that intelligence in at the part level like John's Skeleton Sketch method.
If you are disciplined enough and trust everyone else working on the assembly, fixing may work for you. But, it scares me too much to use that method. I generally make subassemblies with about 20 or 30 parts as a max part count. And that seems to work well for me. But, I don't have anything with 24k total parts though, just 10k.
I got many parts in assy because i need a BOM that suits my project and i think the bigger ones will have 50k+ parts If i would make more 30 part assy then i would have problems with BOOM ( my no SW colleagues would not know how to read it...they are hard with changes lol). Thats why we make our assy that way to help them more.
Hi,
i got a now question,
how can i make 2 different positions in a assy without mates ?
Is there a way or need i a Skeleton Sketch ?
I now that i can insert one part more times and supress that position that i dont need... but i would prefer not to insert new parts if there is a another way
Nice day

If I were you I could create all parts as one part, but different bodies then use the save bodies feature. That way you'll have an assembly file and all parts and no mates would be needed at all.
Sure, you're wanting to design in context of an assembly (we say assy instead of ass ). All components share a top level assy plane structure and are "in place" mated so no need to do mating conditions.
Try searching on this forum for "skeleton sketches" or "layout sketches" for other methods as well.
