I have four curves in the screenshots, but I'm focused on just the upper left one. Here, it's a Bezier curve. I've selected it, then I right-clicked and picked "Convert to Mesh." enter image description here Then I went into Edit Mode and no vertices were selected. In fact, no vertices were visible: enter image description here I searched and found this question asking the same thing. So I tried pressing A to get all vertices to appear and I get this (still in edit mode): enter image description here I thought, "Well, maybe it's got so many vertices that it looks like one long line." I zoomed in. No. Just the line is highlighted, but there are no vertices on it. I tried to use Box Select to see if I could select a few vertices, but I couldn't select anything. Since my goal was to go on and make a prism out of this form (to use as a boolean modifier), I pressed E to extrude and nothing happened. I'm not sure if I can extrude from a line, so I turned all 4 curves in the screenshot into meshes, then joined them together into one mesh. I went to Edit Mode, hit A and moved my pointer as if I were extruding and there was no extrusion. The entire shape moved instead.

Why don't I see individual vertices in Edit Mode and why can't I extrude from this mesh I've created?

    $\begingroup$ You are probably in Edge or Face select mode ... Switch to Vertex select mode (left top header). $\endgroup$

  • $\begingroup$ @vklidu I was stuck in Face Select from earlier today. First time I've used it so I had completely forgotten about it. If you want to write that up as an answer, I'll select it and upvote it. $\endgroup$

    $\begingroup$ @Tango Well, at least I learned something new after so many years. I actually didn't know that... although it's not possible to select anything in Face Select by clicking on it or pressing L while hovering your mouse over it when there are no faces and even vertex or edge selections get lost when switching from the other selecting modes to Face Select, nevertheless pressing A selects everything even without faces. Never bothered to do that, because the other way round it doesn't work. $\endgroup$

You have obviously switched the Select Mode to Faces by mistake.

enter image description here

If you switch it to Vertices, everything should work as expected.

PS: I still wonder why you don't solve this task procedurally, though, because that would have saved you a lot of your precious time by now: https://blender.stackexchange.com/a/268162/145249 ;-)

  • $\begingroup$ Even though I've done a few different projects, I'm quite new at Blender. I'm also having to learn slicing software for 3D printing and for CNC work - and there are differences between slicing for printers and CNC. Plus I'm learning a lot of the tricks and intricacies of 3 1/2 machines (2 printers, 1 CNC, plus a laser etcher on the CNC). That's a lot to learn at once. Plus, one thing I learned back when I was a special ed teacher, I have a different learning style and curve than most people. $\endgroup$

  • $\begingroup$ I don't think you realize how complex your answer is to a new person. Eventually, when I have the full process worked out, I'll likely write a Python script to automate it. For now, though, the critical part is making sure I can produce an end result. And, as I learned in my education classes for special ed, people have different learning styles. What works for one person does not always work for others. $\endgroup$

  • $\begingroup$ @Tango You might be right that I am a bit "blind" when it comes to Geometry Nodes. However, I always try to convey the possible solution in a simple and understandable way, so that you can learn from it in the best possible way. So please bear with me. But I also want to encourage you: Geometry Nodes are easier than they look, and you will get along with them relatively quickly once you get involved. $\endgroup$

  • $\begingroup$ I'm not arguing that your solution doesn't work or that you haven't done a good job of writing it up, but at this point, it doesn't work for me. I used to run a data mining business, mostly written in Perl (that should tell you how long ago it was - Perl was respectable at the time!). When I sat down to start writing it, I had not written a line of code in over a decade, probably longer. But I had people willing to pay for data, so it was a case of, "Get it done and get the data out there." $\endgroup$

    $\begingroup$ As commented above, after all these years I learned something new... 'A' selects everything in every select mode, even vertices/edges in Face Select when there aren't any faces. $\endgroup$
