Operators in Custom properties

I want to include some data in my drawing template to show things like
the area of the part. SW-Surface area doesn't work for me because I
just need the 2D area contained on say, a 4' x 8' sheet of UHMWPE.
I've realized I'll probably have to manually enter a value for this
area, but I then want to take that entered value and multiply it by a
certain factor like 1.25.

Ideally, the designer would enter in the area of the part and the
notes on the drawing would automatically fill themselves in like so...

Area: 32 square inches
Material Required: 40 square inches

Is there a way to multiply values in the value/ text expression box of
custom properties?

You might be able to do this inside of a design table. DT's are Excel
sheets, so all of their functions are present.

 

A macro could do this. I wrote a similar macro a while back that takes
a pre-selected face, finds the area and writes to a custom property
that is then linked to a note. If the face is changed, the macro must
be rerun. The macro is handy for extrusion profiles. In your case it
would need to write two custom properties. Here is a sample:

Sub main()
Set swApp = Application.SldWorks
Set swApp = Application.SldWorks
Set Model2 = swApp.ActiveDoc
If (Model2 Is Nothing) Or (Model2.GetType <> swDocDRAWING) Then
Exit Sub
End If
Set DwgDoc = Model2
Set SelMgr = Model2.SelectionManager
Count = SelMgr.GetSelectedObjectCount
If Count <> 2 Then
swApp.SendMsgToUser "PLEASE SELECT ONE FACE."
Exit Sub
End If
Set selview = SelMgr.GetSelectedObject5(2)

'***get section properties***
sectprops = Model2.Extension.GetSectionProperties2(selview)

'***get area from properties convert to in from m round to 3 decimal
places***
area = CStr(Round(sectprops(1) / 0.0254 / 0.0254, 3))

'***create a custom property in the Drawing***
retval = Model2.AddCustomInfo3("", "CS AREA", swCustomInfoText, area)

Model2.EditRebuild3
End Sub

 

One way you can do it is to add a couple of extra sketches/equations to
the model and then put this into the custom property of the part. This
will then update should the model update. We do this for stock sizes
