Revit MEP - Wire Size AWG vs MM

I wrote a post about this subject before. There is an app at the Autodesk Exchange Apps that offers trap door access to revise the bias toward AWG size versus.

It is called Convert Wire Size (AWG to MM) and it sells for $4.00 USD. I haven't used it myself but for those firms that need wire size reported in millimeters squared it may be the solution you need/want until Revit itself allows us to switch the criteria directly itself.

I'll be curious to hear how well it satisfies what engineers are asking for.

Tip - Control Visibility of Image via Size Parameters

You can't control the visibility of an image file like you can other elements in a Revit family, such as mapping a parameter to the "Visible" parameter. Daniel Stine mentioned this the other day as another candidate for a blog post and I agree!

If you have an image in your family, say a logo for a title blog, you can turn it on/off by increasing and decreasing its "size".

Selecting the image and mapping a parameter looks like this:

It's only necessary to map one of the "size" parameters to make it "zero" high or wide even though my example has mapped both to parameters. As soon as one parameter is "zero" the image can't appear anymore. So I did double the work that I really needed to, didn't take long though, phew!

Here's a video to demo what we are attempting to explain.

Hey, happy April Fools Day! No special post for today...uninspired and lazy! Plus nobody would believe anything I wrote today anyway. The tip is for real!
