The weld tool appears not to be working consistently. If i have a line cut by two othes i then have three portions of the original line I select these portions and weld but sometimes it doesn’t work. The above scenario occors several times in my model. Are the specific criteria required to enable the ‘weld’ to take place?
If the edges that cut the first edge are still present, Weld Edges has nothing to weld. The series of edges being welded must be continuous without any forks.
Here I’ve drawn an arc and exploded the curve so it’s just a series of edge segments. Then I added a couple of edges in the green direction. You can see that welding the edges works for the uninterrupted section but doesn’t weld acrss the intersections of the three segments. Erasing those two edges then allows all of the segments to be welded into a curve.
The second lines are still present but split the new lines. I want to weld the ends of the first lines back together to create one entity (as it would have been before being cut by the 2 new lines)
As long as those edges are intersecting the first edge, the first edge will remain split at those intersections.
Why do you want to weld them?
I want to be able to identify the line properties by selecting just one part of the line.
Once the arc is welded, will a new intersect break the weld?
Which properties? If you want the first edge to be identified as an edge it needs to be one continuous edge, not several that have been welded. SketchUp will identify multiple edges welded together as a curve even if the edges are co-linear. Perhaps you can put the edge you are currently splitting into a group or component to separate it from the other edges so those other edges don’t actually intersect the first.
Yes.
Note that if you use the native Weld Edges on what was once an arc, the result will be identified as a curve, not an arc.
Also, in the case of a single straight edge that is split by intersecting edges, deleting tthose intersecting edges will “heal” the first edge. No need to use Weld Edges in that case.
