When I use sketchup for piping (quite often) I am unable to use the dimension tool upon the line out of which the pipe was originated unless the pipe lies on one of the three planes.
It looks like the dimension tool wants to measure on one of the three planes, and I can’t get it to pull out a measure parallel to the core line.
However, if I use the measure tool upon the surface of the pipe it will pull out a parallel dimension.
Is it possible to obtain the same dimension working on the core line ?
Here’s a couple pics of the pipe
Here’s an example of the problem. The correct measure is 393,5mm but I can’t manage to obtain it when I measure the core line of the pipe. To obtain the correct measure I have to place the measure tool on the pipe surface, and this is not always possible/convenient.
