Power of 10 formating

[Anonymous]

Is it possible to format linear dimensions (possibly through an expression?) to return lengths in powers of 10? (e.g. 1.25 x 10(3) ft.).

For dimensions you can use scientific units in your dim style. I don't know
what other types of C3D annotation can be set to scientific units though.

Yeah, I was hoping to be able to express, say, pipe lengths in powers of 10 through C3D pipe labels. Thanks anyway.

I don't see why not. Two expressions with a series of if then statements. One similar to
IF(PipeLength/10 < 10,PipeLength/10, IF(PipeLength/100 <10, PipeLength/100, IF(PipeLength/1000 <10, PipeLength/1000, 99999)))
and the other like the above, but returning the number of 10's.
IF(PipeLength/10 < 10,1, IF(PipeLength/100 <10, 2, IF(PipeLength/1000 <10, 3, 99999)))
Then use the expression to create the label
FirstExpression x 10 (SecondExpression) ft

Add additonal IF then statements for longer lengths. I may have my math incorrect above, but I think it demonstrates the concepts involved.

What on earth for? You'll only confuse a contractor.

Are you trying for a new linear accelerator?

A local agency wants to have all linear dimensions expressed in light years instead of feet or meters. It will require some very large negative powers of 10.

Light years?????? &^%@*}~+#$. I guess it's a martian local agency..
