WTF is "Reference to Deleted Edge"?????
-
You get errors from SU when modeling? Are they in the ruby console, or where on earth do you see these error? Do they occur while you are actively using a plugin? I guess I pretty much have never tried to draw a line and had SU pop up an error message (I can only think of one excepetion, but it is a different error). Anyhow, please clarify. Maybe even upload the model, or a portion of it.
You said: "but when I selected the 3 edges, and did FACE" - what does that mean? What is FACE? Is that a command in the ruby script?
-
@Chris: That Face command might be Tools> Utilities> Create Face?

First, I fixed the problem yesterday by deleting and redrawing the whole section. But 1 line continued to become 2 segments even when I drew it as 1 long line. It segmented at the point where SU complained about the hidden line before, but this time I was able to "Create Face" by selecting the triangles perimeter (4 segments, rather than 3).
However, I cannot replicate the error message in that area this morning, so sending you the model here will not accomplish anything, but if it recurs, I will, to this post to maintain the thread. It is a spiral ramp to a parking garage that I plan to put this on the warehouse as a module.
So to answer questions, I do not get that message pop up as I draw. It happens when I modify an existing part of the model, and as I create the triangles, some fail to form the face. Usually it is a result of a tiny fragment separating the endpoints. That's now easy to fix, once I've found the culprit. Then I just select the 3 sides and "Create Face" Either the face forms, or I get the message "Create faces failed". BTW, I have a K/B shortcut "F" to Tools> Utilities> Create Face
But in 2 instances in this group, and a very few other times in other models I get the "Reference to a Deleted line" message. Usually a redraw of the face perimeter fixed it, but this time, it took a lot of effort to fix, and that's only because I redrew a lot of surrounding geometry. The problem face was reconstructed from 6 triangles.
The "Deleted line" is a mystery. There was never a "line" or any geometry at the point SU complained.
It happened as I deleted a face on the side of a circular wall in order to insert some additional geometry. That particular set of entities did not meet my requirements, and was deleted. But the bounding 4 lines of the original face were never affected, so I tried to redraw 1 segment to reform the face, as I have done successfully many times before. That's when I got the message. I ended up deleting the 2 adjacent faces, which reformed immediately when I drew the 4th edge, but the face in the "deleted line" area had to be made up from The group was drawn fresh in totally virgin territory, and is contained within its own group from scratch. -
I didn't see mention of this- and maybe it doesn't relate- but when you need to form a single edge of two sequential segments, you know you can draw a line segment from the break, out into adjacent space a short distance. Then erase this segment. A single line segment should? be formed. What about some microscopic gap being somehow created in the process?

I don't really understand what you mean, but there was no gap. It was a single line that for some reason SU8 broke into 2 lines. (See drawing). All those faces formed by triangles to either side resulted from the fix. They were 4 sided faces on the curve before I started to edit. The edit (a hole) is not yet reconstructed in the picture, and was to be centered just above the short horiz. line above the break point.
From all the answers above, I suspect none of you has ever seen this message.. yes/no?

To date, I have not seen the message as you describe. But considering the amount of time I have spent with Sketchup, discovering its idiosyncracies, and the time I have spent studying the postings on this website trying to learn more, nothing surprises me with this program.
I assume the condition occurred before you formed the eyebrow like projection above it? -

It happened after the "eyebrows" were added. They are the inside support ledges for the actual ramp segments. This structure is the center core inside which the vent shaft is located.
What you see is 1 story, out of the 3 parking levels. I was adding in the vent holes when the problem occurred. It is not finished by far. It next needs to be horizontally split in 4 rings, to be stacked 12 high. What you also do not yet see are the outside walls and columns on 3 sides supporting the ramp segments at their outer edges.

Do you have some 'raw geometry' on various layers, some of which might be 'off' in the same location as these 'error edges' ?
Layers do not separate geometry, but groups and components do.
You may have something that is invisible or partially visible [like a face on an 'on' layer, with its edges on another 'off' layer].
Always put 'raw geometry' on Layer0 and group/componentize them, and then give those a layer to control their visibility...Layering 'raw geometry' is the path to confusion... if not insanity..............

With all due respect Tig; I learned the hard way a long time ago about layers, layer0, groups and components. I NEVER draw on anything other than Layer0. One of the first things I did to troubleshoot was to toggle the layers with all lines visible just in case the line was hidden there. I even reset all the internal geometry to layer0, even though it was all on layer0 anyway.
As I stated before, this group was drawn in totally virgin territory in my model. There was never any geometry even near where it was drawn. Also, it was always, since started as a raw circle, been a group, on its own development layer. ALL its internal raw geometry is always on Layer0, and there were no nested groups/comps within the group. Once the development reached a certain stage it was split up into several components to create copies in the overall model.
There are 2 separate comps on another layer adjoining the central cylinder, the main floor ramp, and 3 copies of the ring ramps, which were created prior to the problem, but none of their geometry intersected with the problem phantom line.
No matter what was redrawn, if any new line came near that phantom line, I got that message when I tried to face. The only way I was finally able to "fix" it was to draw a new set of faces (pyramid fashion) from the bounding edges with the vertex slightly projected out from the phantom line. Then I moved that vertex to line up the faces with the perimeter of the cylinder, hence those extra triangles in that area. That effectively killed the phantom line as I can no longer recreate the problem.
I had the same problem in one other area, but that got fixed with just deleting the surrounding lines and redrawing them. But this one was real stubborn.

I am guessing here, and most probably will get corrected:
If this was a circle extruded into a drum, I will bet that the circle is a closed curve, you did some outline with Tools on Surface to generate the eyebrow, then did perhaps a Joint PushPull to project it which sent some spurious signals to the program "behind the curtains". It interrupted its connection with the curve.Wrong? Oh, well.
