      It is fascinating to see the differences in the interpretation of the shape. I guess it is about expectation. So far you are mimicking but neither shape look much like the original on close inspection....or is the expectation lower than I think in this case.

      it's more about the approach.. which could be applied to actual dimensions if need be.

      fwiw, the original picture was drawn earlier today in the same loose manner. it's a lot easier to do in rhino but i wanted to see how people might approach it in sketchup.

      [edit] here's how the original one was drawn.. (and you'll notice i took a similar approach in sketchup)
      a lot shorter though no voiceover.

          Hey,, Nice training!

          Hi Jeff,
          I see you pursue with your specific technique using Uniform B-Spline
          Bravo for the video which explains very well.
          And also I must say that watching the second video, Rhino seems to be an extraordinary modeler!!!

          thanks, simon

            Nice Jeff, the video really helps understand the process.

            Here's another simple training exercise...I'm curious how you guys model the intersection of a curb and driveway, or curb and crosswalk. I'm hoping there is an easier way than I currently do it. I'll post my method a little later.

            Reference image of what I mean...

              i take it the curb's profile is angled sides with a flat top and rounded edges?
              something like this?

              curb.jpg

              [going with modelhead's advice.. i'll update the top post to highlight&link to additional challenges added to the thread]

                Like this:
                Capture2.PNG

                Then it flattens out at the driveway.

                  oh, i didn't see your other picture prior to uploading this video but i think you can do it the same way as i'm showing only without the arc.. just an angle down for followme..

                      Hi Jeff,
                      You are "on the fly", please keep it on 👍 👍

                      RE1:
                      I would really like to love Su developing team as I love SketchUp and its fair community.. But What they do and what they don't do is unpleasant to me 😢 . Boolean Tools is their tool of the year (one tool=one upgrade: I'm not kidding so much) ( 😆 ) and they dig one more step the gap between free and pro versions. I say to u "GSUTeam : your mind is wrong! Can you hear that?"
                      Anyway I have bought Whaat BoolTools for long and for 10$ and which works perfectly until SU5 so Dear team no matter to spend xxx$ for SU8 pro 😡

                      Holy sh!t, thanks Jeff - I never thought to use undo to go back in order to copy a face, then move forward to paste it - brilliant.

                      +1 👍 it is also what I had thought when viewing the video.
                      This remind me a tutorial which was on the old SCF tutorials section
                      A tutorial dealing as you do with the "Undo command" and named "Back to the futur"
                      At this time I was new to SketchUP and the concept was hard to me.
                      Now I can take advantage of it, it has disappeared...

                      But hey hey
                      There is Internet Wayback Machine !!
                      and Here is Back to the future tutorial:

                      Cheers,

                      simon.

                        Yea that go back and copy forward is a nice little trick. I probably thought it would violate the laws of causality and entropy and so never tried it. But Jeff, I believe is a Tralfamadorian and I am a mere earthling.

                        LOL.

                        thanks, simon

                        that move i do with the extension line for the b splines is basically an adaptation of what i see happening in other modelers only those one usually do it automatically 😄
                        notice in the rhino video that i don't do any of that stuff because it's already happening within the tools.

                        and yeah, rhino is great.. i'm slowly but surely learning the ins/outs of it and it may just one day eliminate sketchup from my workflow 😉 [actually, i don't really think it will becasue sketchup is just way too fast to draw simple objects (walls,slabs,etc.) which in reality is most of a drawing i may do.. when the compound curves come into play though, i'll be using rhino for sure.

                          That's really close to how I made the curb, Jeff. Your way is faster using the Solid tools...I need to learn the ins and outs of them.

                          Here's what I did:
                          YouTube - Dropped Curbs in Sketchup
                          [flash=640,385:vyudgand]http://www.youtube.com/v/u2Hb3NF6ZZg?fs=1&hl=en_US[/flash:vyudgand]

                          I split the curb into 2 sections, made a separate follow-me path for each section, then used Intersect to get rid of the excess (I didn't have SU8 then). Now, I couldn't get good results with Union, maybe because of overlapping faces? I'll have to play more with the Solid Tools.

                            Well, I don't do too much else around here, so, if I can make one person laugh, it's not a total loss. 😄

                            I take the slow, deliberate approach in my aimless wandering.
