Hello,

I'm trying to build a crawler crane boom with jib using weldments. It is a school project where we have to improve an existing faulty design. I want to then test my improved construction dynamically in SolidWorks.

The wire structure of the boom is on the front plane. From there I created a new plane 1250 mm behind - so to speak - the front plane. On this plane I drew same wire structure but 50% offset. I haven't gotten to the jib yet. From the front plane the back plane the line tool doesn't catch.

I'm forgetting something really simple I suppose. But I'm stuck. Please help.
