  • Alignment on pipes

    Hi!

    I time to time measure pipes with a portable arm. So far it has been pretty easy to do it but now i'm facing som pipes with many angles and different views for evaluation.

    I usually use program mode but have also started using auto element. The problem is the alignment. I have tried several ways to do it but it just goes crazy. Even if i get origo for XYZ the way i want it the rest of the elements seem to be projected crooked and way of the CAD model.

    Has anyone experience with measuring pipes? I could really use some good advice here.

    Sorry for my bad english.

    There's actually a special tool and module for measuring tubes.

      Yes i know, but we are far from buying one of those. So i will continue using the probe.

          Most of my tube inspections were with 1:1 mylar. Have you done a forum search? I'm pretty sure there are a bunch of topics on inspecting tubes already.

        One method is measuring all the straight cylinder parts, create the intersection points and bestfit align on them.

          Make sure the nominals are correct and that the direction of the axises matches the direction of the CAD-model axises (positive/negative).
