Revision Table

In this post I will share what is the best method to increase the revision number on the drawing. While this can be done in several ways there are a couple of things to consider, like choosing the scope of the revision and the revision table type (single/multiple entries).

First let’s identify the different types of revisions. When you place a revision table on a drawing you will be asked if the scope of the table will be Entire Drawing or Active Sheet.

Revision Scope

If you choose Entire Drawing then all sheets will have same revision number linked to the drawing iproperties.

TIP: In the Revision Table placing window make sure that “Update Property on Revision Number Edit” is ticked.

Choosing Active Sheet will mean that each sheet will have individual revision number controlled from the sheet properties.

Sheet Revision

You might ask yourself why would one need to control revision for each sheet? It’s all to do with internal specification, document controlling and validation. Some clients have one drawing number for all sheets and some have a separate drawing number for each sheet. Think of them as separate documents each with its own part number and revision/issue number. In some industries each document needs to be tracked, linked and controlled.

TIP: Remember to change your titleblock to indicate sheet revision rather than drawing revision.

 

Titleblock Revision info

Multiple entries Revision Table:

If the company standard is to show all or predefined number of entries in the revision table (like showing last 5 changes) then know this:

                The correct way to change revision is by choosing Add Revision Row on the contextual menu when you right click the revision table but you can also do this while editing the revision table. This will update revision on the sheet or iproperties as well which in fact will update the titleblock.

Correct way to add revision

                Do not choose add row because that will not update drawing/sheet properties or the title block. The number/letter you add with the add row will not be considered as a revision number and next time you choose Add Revision Row the numbering will increment but it will ignore your manually added row value.

                Do not change iproperties manually because, even though it will update title block, this will mess up the revision table. Changing the revision number in iproperties will not increase by adding new row and it’s same as if you edit the table and change the number manually.

Single entry Revision table:

If you company standard is to show only the current row in the revision table then changing iproperties might be your preferred choice. Entering a value in iproperties will override the last row in the table and will update the title block.

TIP: Remember that you can open iproperties from the revision table but even faster you can bring them up by right clicking the drawing name in the tabs or in the browser like this:

               

Getting the iProperties window.

                Either way you choose to use this I hope I gave you some good info to speed up your workflow.
