Polyline molding-as-plumbing pipe length display

[ChiefTesoroTX]

I was (naively) thinking that %length% would work to display the length of a pipe.  Tried as many variations as I could find, all the online help references polyline area, but I've not seen anything for length.  I'm hoping to have it displayed in ft' in".  Is this easy, or are macros a whole new thing I need to go deep into?

Try using %perimeter% which will display it in inches.  I think you can use %perimeter.to_s("'-\"")% if you want feet and inches.

If you're using a closed polyline, then %length% will not be an option.  As @DBCooperalready stated though, you can use %perimeter%.  The problem though is that you're going to get the entire perimeter of the polyline and not necessarily the length of the pipe that the polyline is supposed to be representing.  Assuming though that your "pipe" is a specific width and that and that its a pretty consistent width closed on both ends, then you should be able to use something like the following:

 

%((perimeter.round-8.in)/2).to_s("\'-\"")%

 

...where the number 8 is just double the width of the "pipe"...

NOTE:  I rounded the perimeter value just to avoid a more complex fractional inch value macro but this should work for a basic length.  Just make sure to replace the number to reflect the actual width of your pipe.

If you need anything more complex or need things tweaked further, please feel feel to reach out.  I do offer consultation services for this exact type of thing.

@Alaskan_Son nailed it, you taught me three different things with that reply.  Is there anywhere in the docs or help to find a listing of what the different macros like %length% and %perimeter% are?
