      I am a newbie, so be kind. I am trying to get up to speed fast for a bathroom remodel job.

      Here is my current problem:

      I am illustrating the a small 3" riser at the entrance to a shower and I need to show the underframing, mortar bed thickness for the tile and the tile thickness. See this image: http://picasaweb.google.com/lh/photo/ztYPzyiSZZqt_dNULiNyRQ?feat=directlink

      I have the various material borders defined and the wood framing pulled up to the proper height. My next step is to pull the mortar bed up and above the wood framing (by 1 1/4") to surround the wood with mortar. When I pull up the mortar bed and then drop it slightly, I notice the wood framing now takes on the mortar material. See this image: http://picasaweb.google.com/lh/photo/cmgjwb2hCPjXkKaH99TOjA?feat=directlink

      Additionally, when I bring the mortar above the wood framing, the wood becomes a flat plane again. See this image: http://picasaweb.google.com/lh/photo/UGuiedITW77YcSbVpMqbUA?feat=directlink

      I suspect there is a way to "lock" the wood framing so the new mortar material does not alter it when passing over the surface, but I am at a loss.

      Any hints are most appreciated and I am excited to have found this forum!!

        If you make each piece a component, you will be able to keep the materials separate. Is that a piece of 2x material? with mortar underneath? before you bring the mortar up triple click the 2x material and make it a component. then when you bring the mortar up it will not take on the material of the wood. By making everything in your model a component it will be easier to edit discrete pieces of your model. Hope this answers your question.

          Try making each part a group or component?

            Thank you so much.

            Now that that is working properly and I want to show a cross section using the Section Plane Tool, I am assuming I need to manually close the ends so the components do not appear hollow?

            Here is an example of one that needs "clean up" for the construction crew: http://picasaweb.google.com/lh/photo/39HYhlDDtlyr7HoHtOf6kQ?feat=directlink

            TIA

              Hi Monkminder,

              One "workaround" to solve this hollowness is to set the back face colour to black and you cannot see anything of it then. This is mainly a good way when you make a section cut animation because for stills, there is the SectionCutFace plugin by TIG:

                Thanks for the help. The Component method got me over the hump.

                General question since two solutions were offered. One being Grouping and the other making a Component; is there a general rule of thumb as to when I should use one over the other. In my mind I would use Components if it is a part that I would use over again in the same or other project and I would use Groupings for one-offs. Does this logic sound OK to you?

                TIA

                  That's correct.

                    Many people [*] preach that you should just always use components. When you have a model full of components and groups, and you grab a group and make a bunch of copies of it, its hard to know if its a group or component. Then then once you've made a bunch of copies of a group, it can be a real pain going through the model and converting them all into components.

                      Yes, components, though similar to groups, have some "extra powers" and you can practically handle them as real true, separate "mini models" embedded into your model. What they can do (and groups not):

                      • change one instance and thus change all the other ones (just like Chris mentioned above) i.e. they are linked together
                      • use one definition with several instances and SU will only need to count the file size for the geometry of one instance (this won't help performance issues unfortunately)
                      • change axes
                      • export/import them ("Save as..." and "Reload")
                      • add gluing and cutting planes (groups can glue, too but you cannot control their axes therefore nor the gluing plane)
                      • well, and lately make them dynamic with SU Pro but that's something special...
                        However just quickly (and often temporarily) keep a set of geometry together / separated from others, grouping is just fine

                        What would SU do if you 'Grouped' several 'Components' and made multiple copies of this 'Group'?

                        Would it still only consider that only one 'Component' is present or because of 'Grouping' has SU now considered each 'Group' as independent geometry, thus increasing file size?

                          I have tried to play around differently nested component to see how the file size changes. The case is that if you use only components to nest other components and make copies that way, it will help "compressing" file size even further but there is a practicaly limit of this as you do not necessarily want to build up everything from deeply nested components (also, this may even affect SU performance). Other times only the fact that a new component instance has to be counted (it obviously needs some bytes) can even increase file size if otherwise the geometry is not too complex in it (i.e. it is not economical to make a component).

                          See this file below - it is made up of one, single component which then I made into further components where possible and the two aisles of the vaulting are made into instances of again a higher parent component. Everything was made by simply scaling from outside differently.

                          Start exploding the bits, save and see how file size changes. Not too much until you explode the lowest level components into their raw geometry but then it is significant.

                            Thanks for the example πŸ‘

                            After exploding all the way to raw geometry the file increased by 80% 😲

                            As i played around with exploding the higher level components the change was not so dramatic, as you mentioned, but i imagine that choosing when to make a component is key to file size.

                              Yes, indeed. And this one-piece vault is not even a very complex geometry.

                                  Maybe just one additional thought if the topic is bumped anyway; when you make a group and later (when you do not need it) explode it, there won't be any (noticeable) traces of it in the model.
                                  An exploded component will however remain in the file and you can still access it in (and insert it from) the Component browser.

                                  This way, if you are not careful enough and keep playing with various ideas and download several components (of uncontrollable file size) from the Warehouse into your model, even if you discard them, they will make your file size really huge. Therefore you always need to purge your model regularly (although be careful NOT to purge whatever is needed) See example below:

                                  http://lh5.ggpht.com/_zcvsIuYiVbo/S213qeB-iXI/AAAAAAAADdw/h6GgIwzToSk/PurgeComponents.jpg

                                  There can be unused components, materials, styles and layers in a model. The first three can considerably boost the file size (styles only if you are using some sketchy style with high resolution watermark background image for instance). In every similar dialog, there is the option to purge them OR you can do it altogether under your Model info > Statistics tab.

                                  Lately the 3D Warehouse warns you of unused items (such as above) and offers you to purge them before uploading. This is cool IMO - otherwise one would import Sang or Bryce like a thousand instances after each other. 😲
