I am exploring/working on a top-down assembly model. It was fine, but all of a sudden, I realize the master sketch inserted in the current part (weldment), not updating. Not sure what went wrong.
I rather like to know how can I get the derived entity updating.
Please help. Thanks.
The ? after the > means the reference is not open in RAM. open the part in another window of the same session. updates should then flow...
Or you were editing the sketch and haven't exit the sketch yet?
Sometime you need to close everything and restart SW.
.. right mouse button to view it's origin?... maybe the file is not present or someone renamed a component so the link maybe broken?... if it's broken, you will need to re-link or re-sketch.
You are right. I see that is fine.
But, it appears that, blocks in master sketch do not update in master sketch in the derived document.
Do the block in master sketch not update in the derived part?
How can I get the blocks updated?
Thanks.
Good question but, I don't use block. Just sketch.
Thanks Frederick.
I tested with out the block. Instead, I used a sketch. Tat is doing well.
I think, the blocks do not update across documents.
I am still struggle (using Inventor <---> Solidworks)!
Yes, SW handle MS differently.
BTW I don't use block in IV either
Blocks are so AutoCAD.
I would try turning off the reference sketch flag on those sketches...
Thanks. Can I do it.
How can I do it. Please elaborate. Thanks.
These are my first very beginning derived parts.
Hi Jeremiah
I would like to explore with your idea,
What to do men by ".. turning off the reference sketch flag on those sketches..."
I request you provide me with a little more details.
Thanks.
These symbols are to indicate the sketch as a "reference sketch" (new in SW2020), and I have seen some posts about them not behaving as users were expecting - especially with blocks. we are stilI=on 2019, so I have not played with it yet. but I believe the toggle back to a regular sketch is in the right click menu.
and as a side note: sketch blocks are by default not linked to anything outside of the file they reside in - when a block is added into a sketch or drawing, it is copied to that file. there is an option to link it to the block file saved out on a hard drive, but I believe that is only available when the block is first inserted (we don't use the link option, we find it too risky without a way to see where it is all used/linked)
I think the reference sketch symbol is added to derived part sketches (different from derived sketches) automatically to indicate that they can't be edited.
That could be, are you on 2020 to test that theory out?
Thank a lot Sir.
I am exploring all your suggestions.
Meanwhile, I was also working on me blocks. I found way to do with blocks across documents.
The procedure is:
2.1 Select Sketch_for_Block_1
2,2 Select a plane (the same plane where Sketch_for_Block_1 sitting can be selected)
2.3 Crete block using Tools > Block > Insert
This new block can be populated anywhere needed. It updates in all down the road documents (derived parts) when the Sketch_for_Block_1 is edited in the parent document.
I got the idea from the Utube video posting: YouTube Thanks Ron Grover
Hi Rohana,
There is a big difference between "derived sketch" and "block instances". The derived sketch feature has been very robust and update reliably. A derived sketch is nothing but a standard sketch, that pulls the geometric relations and dimension from an existing sketch. An automated copy. Sketches are the bread and butter of SW. That doesn't fully apply to blocks. Reading your procedure, I think you mean "derived sketch" and not tool-insert-block.
Even if blocks would update across different components, I would not use it in your application. Blocks work great in some aspects but have too many flaws if you use them outside these boundaries. They work better at component level and are more restricted in drawings. In a nutshell, use them wisely. In general I would not recommend your approach to using the insert part feature for master modeling for many reasons. You say you have plenty experience with IV and assume you have already designed large assemblies before. So you would know what you are looking for in terms of function, reliability and operator skill requirements.
The pitfall of large assembly is performance and the ability to control model changes accurately. Plus getting drawing & BOM updates in a reasonable time & effort. How you split your grid and how you place and design your sub-components is more important. The master model sketch itself is only a tiny piece in this equation.
Two things. Large assembly modeling is difficult to setup efficiently. Even for experienced operators. Let alone if you start out using a new software. If a chosen workflow is difficult in the beginning, it most likely will not get any easier if you pack it into a large assembly.
I suggest you spend good money and find someone with proven transferable skills (important!!!!!) that can give you good advise towards your company needs. What ever solution you choose, make sure you spend some time and set up a simple decision matrix and compare it in the end with your actual model performance.
SW is simply a toolbox. Your requirements will determine which tools to use and what not.

Dear Mr. Klammer
Thanks a lot for the reply.
I agree with you. I appreciate your reply: will closely follow with your content.
Since mid-April, I am continuously using Solidworks (Likely, I forgot my Inventor). At this moment, I am exploring how to create an intelligent huge assembly using the top-down approach. The belt feeder is aimed at getting through the skills.
My first approach was the layout design. This approach contained a single layout sketch (with planes created within layout sketch). It is tricky, this 3D sketch goes out of planes: but, I was doing well. Down the road, however, it gave me a hard time. The sketch was always shifting. I could not fix it, I gave-up. By now, I realize that it was because I was using the Ctrl+V to insert the parts where I thought, it would share the same origin always: but, I found, it does not do so. I will go back to layout model.
I switched to do with a master sketch. It is, currently, going on well.
My agenda is:
By now, I am getting comfortable in Solidworks.
I aim at using a combination of the techniques to suit the design environment.
Once again, thanks a lot for your time.
here is some good reading material...not the latest version but the principles still apply
Hi Elmar;
Thank you sir, for the reply with attachments. They both are amazingly good: I will go through very closely - for several times. I will update you with the progress.
In 2005/6, I was very good in Solidworks. But I got to work using Autocad and Inventor at work also since then.
I feel sorry for myself - my Solidworks skills died since then. In those so early days also, Solidworks was so good: aimed at what the industry needs from the beginning.
I am back to Solidworks as well. I aim at getting better or capable.
Thanks again for the help.
Yeah, I tested that in 2020.
You are right. I can't do anything.
Thank a lot Sir.
