      u can select the block and deselect the hole and the up and down face later pick up the scale tool press control and make it wider in x and z axys don t forget to resize it same in both axys

        Thanks for the reply, but I think I need to clarify my example. The idea is to be able to create the hole in such a way that it stays in the middle of the face regardless of how I resize the block in any dimension. And that the hole stays round. I don't actually need to do this particularly, but it is a basic use of the tools provided by solid modeling software.

          Dear Kyle,

          The simple answer is no. I use Inventor and know exactly what you mean. Sketchup doesn't offer parametric modelling, and neither does it have the functionality to produce standard, dimensioned drawings from the 3D model. I use Sketchup as a front-end design tool for working through design options, and find it it very useful when used in this way. In the case of Inventor, one can export models, via AutoCAD, into Sketchup and then use Sketchup's free-flow modelling to tweak designs before making changes to the Inventor model. Perhaps I could do all of this in Inventor if I were more skilled, but I am not and so I make use of the tools I have. I also find that my Inventor models are cleaner and have fewer steps because I pretty much know what the part looks like before I start, which is big bonus.

          Kind regards,
          Bb

            Hi Kyle, hi folks.

            See this SU file for ideas.

              G'Day Kyle, and folks

              you could always try using the scale about center, using the scale tool hold ctrl and scale to size required hole will stay centered , but will increase in size as you scale the cube

              just a thought

                Hi Jean,

                I had about the same idea as you. One comment though; in your step 4 you need not even redraw the segments on the ellipse just delete it - the face will "heal" itself. Then just explode the cylinder and intersect it with the block.

                Gai...

                  Whats all this about redrawing the circle? If you just select the 2 end faces you can scale them straight off, no need to bother redrawing anything.

                  Saying that, all this is kind of beside the point, SU cant do proper parametric modelling. True it has some very basic functionality in its auto stretching (or whatever they call it) but its not the same.

                    Dear All,

                    Perhaps Oscarlok's dimensions plugin (still a work in progress I believe), might add a little more functionality to dimensioning.

                    Just to remind you:

                    Regards,
                    Bob

                      Is that a ruby script ? It looks good

                        Smart (Interactive) Dimensioning was proposed quite a while ago by Rick Haws

                        See this:

                        ...............
                        Initially, it looked very promising.
                        Hopefully, future development will finish this plug-in off.

                          Hi Remus, hi folks.

                          Good trick about selecting the two faces. Using symmetrical scaling do the trick and you can type an exact value in the VCB.

                          Thanks.
