I only see the breakline tool when I right click on the polyline   The only break tool on the tool palet across the top is a breakwall.  This didn't change in X7 did it?

For better clarity- here's the plan with lot's of detail deleted (terrain and confusing layers aren't displayed) and the molding converted back to a polyline- that I want to slice where the intersecting segments are placed.  What am I doing wrong?

Glenn, To be clear.  I converted the molding back to plain polyline.  I'm being unsuccessful in cutting the polyline- it's placing a node on the polyline.

I tried converting back to a plain polyline -- without luck using the break tool?  Rightclicked on polyline, then picked break tool-- then double clicked where I wanted it slice- and it placed a node.  What did I do wrong?   Also, I thought you could use an intersecting line to cut a molding?

I'm using X6 build 16.4.1.20x64

glennw, I clicked the tool and then double clicked the polyline at the point I wanted to slice it

I deleted nearly everything outside of the pool area and realized that I was starting to alter terrain elevation data.   I left terrain features displayed but he items of interest are in layer called temporary and you may want to hide terrain features layer to clarify access.

Glen,  Your description of the problem is correct.  I did try doubleclick with the Break Line tool and it added a node instead.  Tried converting the Molding to Plain Polyline and doubleclicking with Break Line and had same result.

Alaskan_Son,  it's a really big/complicated plan so probably easier to describe.  I created a swimming pool from a closed polyline using a series of terrain features, etc- including specifically a collection of moldings extruded on the inside of the polyline. Since several objects now have the same boundary defined by that polyline, I put the moldings,  and lines intersecting it where I want to cut, and a separate temp layer to facilitate access in planview editor.  I've tried Trim tool (using the intersecting lines) as well as the Break Line with double click.  Trim tool told me I couldn't trim the object- said the same after I converted it back to a plain polyline.

I've spent the day watching videos and searching forums without luck.  I have a set of moldings extruded on the inside of a closed polyline that I want to "slide" vertically and apply different heights to.  I can't trim or otherwise slice the molding.    Tried trim on polyline itself without luck.  What am I doing wrong?
