Keep Balloon Numbering Consistent

Wednesday, January 12th, 2011

Recently, I received a call from a customer in Columbus, OH, that designs and manufactures a variety of sheetmetal components for shelving and fixtures.  As you can imagine, a complex shelving design may require several drawing sheets to adequately describe the product to the shop floor.  The Shop wanted the Engineer to maintain balloon part numbering from the first drawing sheet to the last drawing sheet.  Personally, I don’t blame the Shop for wanting their information as clean and concise as the Office personnel – they already learned about stable item numbering in Enterprise PDM several months ago.

Sheet1 is an assembly drawing with an Indented Bill of Materials using the Flat Numbering option.  I’ve added the balloons for two components that make up one of the sub-assemblies for a pressure vessel.  The Shop wants the Engineer to create drawings where the numbers are consistent, regardless of the drawing sheet.  For the example, balloons 26 and 27 need to identify the same component on all drawing sheets.

Drawing Sheet1, Indented BOM, Flat Numbering

Sheet2, shows the sub-assembly that includes components 26 and 27 from Sheet1.  With a simple RMB in the drawing view, select Properties.  This brings up the Drawing View Properties dialog.  Check the box for ‘Link balloon text to specified table’ and then select ‘Bill of Materials1′, which is on Sheet1 of our drawing, the balloon numbering on Sheet2 matches Sheet1.

Give it a try the next time the Shop complains about your drawings and balloon numbering!

Enterprise Users Want Their Stable Item Numbers

Thursday, April 15th, 2010

I awoke this morning to an angry mob at my front door. Millions of SolidWorks Enterprise PDM users with pitchforks and torches. Apparently they had read yesterday’s blog where I had given the SolidWorks nation the information they have been yearning for on keeping stable balloon numbers for the components in their assemblies.

[I suppose it is logical. This group of users is typically very interested in sharing BOM information with other systems -yet Enterprise's calculated BOM doesn't have balloon numbers?]

We want our stable item numbers!!” they shouted.

I quickly pulled out my projector & trusty laptop and displayed this image on the side of my house:

ShowBOMFromTable

Look!“, I shouted

Any BOM table you put in your drawings or assemblies can be displayed in the ‘Bill of Materials’ tab. They are available in the dropdown list under BOM type! So if you followed yesterday’s blog correctly, all of the work you put into that BOM table can be displayed here for everyone to enjoy!

Now, you! Pick up that blood! …and if you all come back peacefully tomorrow I’ll show you another way to get item numbers into your Enterprise BOMs!

Stable Balloon Numbers

Wednesday, April 14th, 2010

In the beginning (1995) Jon created SolidWorks that had the ability to assign balloon [item] numbers to parts…and these numbers could be added to the bill of material. And Jon saw that it was good.

The problem was that if you changed the order of your parts in the assemblies the balloon numbers changed. This wasn’t terrible because the drawings and BOM always stayed up to date, but a little bit bad because if you passed your BOM information to external systems it was difficult to match line items up from one revision to another.

Throughout the years things got a little better – balloon items no longer changed when you reordered the components in an assembly, but if you deleted a component, all the components in the list below would move up in the BOM order taking the deleted component’s place – and its balloon number.

And we wept.

Then in [I think] SolidWorks 2009 along came this little BOM table property!

DoNotChangeItemNumbers

Select this little golden nugget to prevent BOM item numbers from updating when you change item numbers elsewhere.

I’ll grant you that we have had very good control of our Excel based BOM tables for a while now, but I haven’t used Excel based tables since we’ve been given the ability to update component’s file properties in the SolidWorks based BOM table.
