      TIG, I seem to be having a problem with your script. I have installed it and WorkPlane, but when I select edges and faces and run Plugins>Flatten to Plane nothing happens whatsoever. I have reinstalled both plugins, with the same result.

      I am importing a plan, but the lines somehow are not intersecting the plane. I tried selecting and Intersecting with Context, to no avail. I was hoping flattening them to a plane would eliminate the possibility of the lines not being co-planar, but I can't get Flatten to Plane to work. Thoughts?

        CAD drawings are notorious for having tiny gaps in lines so faces won't form.
        Have you tried Thomthom's Plan tools or one of the other tools written to cope with such imports?
        Projecting the edges to a plane might work, much as draping them onto a big rectangle will make them coplanar... BUT if they don't form closed loops then whatever you do it won't make them 'face'... unless you 'heal' the gaps etc with specialized a script...

          Thanks for the suggestions. I checked it with Thom's EdgeTools, and everything is connected. They just won't intersect with the face. When you say projecting them to a plane, it was my understanding that that's what your plugin does. I did figure out that the reason FtP would not work is that I was trying to do it within a group. Once I exploded it, it flattened fine, but still did not intersect (I ended up with what I started with). I also tied the Sandbox>drape, but it doesn't recognize that plane as a mesh. I then drew a rectangle, deleted the face, then made a Sandbox from the remaining edges. That allowed me to drape my plan over it, but still it would not created the individual spaces of the rooms! What else can I try?

              Ok, it actually seems to be a problem that I have a lot. When I bring in a large CAD file, for example one that has a long road or sidewalk, which should be a continuous face, SketchUP doesn't recognize it, even when I run Make Faces 1.4. I have to "remind" SU that there should be a face there, by gradually connecting it.

              http://img825.imageshack.us/img825/240/closet.png

              In this example, all I have to do is connect these two points, and then a face is created. Then I can delete the line I just drew, but the face remains. In general, the Make Faces tool works really well, just not on large or complex shapes. Anybody know of another tool that might work better than doing it manually?

                Have you tried my AddFaces ? [see Plugins Index]
                Why not post a problem SKP and let us see what we can do ...

                  Ok, will do in the morning. I'll also look up Add Faces and try that. It's quittin' time for now. Thanks.

                    Ok, I tried Add Faces, which didn't work any better the first time, then locked up SU the second time. The only solution I've found so far is to manually do it, as shown in my earlier post. Feel free to mess around with the file though.

                      Your CAD drawing has lots of edges that will never be able to 'face' - like nibs to closet alcoves etc.
                      The door swings are often many small segments and there's a limit to how many segments can be coerced into taking a face in one step - so the rooms won't face individually.
                      It's relatively quick to draw a few rectangles over the hotel[?] rooms/alcoves and force faces to form, and then erase any unwanted edges - the Style you have set helps as the end points are clearly marked...
                      Because most internal walls are single lines anyway, aren't you going to over draw with a centered wall anyway? Which rather removes the issue of adding faces to the imported CAD-layout as it's somewhat useless anyway - even it it did take faces to even single 'room' ??

                        Well, the intent is actually to just use this a s a diagram, with no walls. I will need to color the rooms separately, so it is necessary to have faces for each room.

                          It'll take 5 minutes to overdraw rectangles on the rooms to force separate faces.
                          Then tidy up unwanted edges etc - presumably you'll want a line across doorways anyway ? which you don't have had the CAD line drawing accepted perfect faces anyway - the corridor color would spill into the room/entrance-area !

                            Hi TIG
                            First time here. Have installed plugin "flatten" & "workplane" read all the posts above and still I am not able to get this to work. Must be missing something. SU pro8 - model component. I open the component create the work plane centered on the component select the work plane (unlocked)and the blocks within the component and start flatten from the plugin menu and..... nothing happens?

                              The one selected Workplane simply defines an 'infinite' plane in 3d onto which the vertices of the selected edges [or edges inside selected groups/components] will be projected as a 'flattened' version, when you run the tool.
                              These edges must be 'visible' [i.e. not hidden/smoothed or assigned an 'off' layer].
                              The Workplane can remain locked in place, if desired.
                              When you use the tool do so with the Ruby Console open and see if there are any error messages.
                              Are you sure nothing was made? If the plane is flat and passing through the bottom of vertical faces then the 'flattened' edge group will be entirely coincident with the other geometry and so you might not see it immediately. Use the Outliner to see if the new group exists...
                              If you are definitely getting nothing made or have inexplicable errors then can you wither post the SKP or a screenshot so that we might better understand what it is you are attempting.

                                Hi,

                                It looks like I am coming to the thread a little late.... I was just wandering weather it would be easy to change the script slightly so it deleted the originally selected entities and didn't create a group for the flattened entities. So bascially the selection just gets replaced with a flattened version.

                                This would be beneficial as I use the tool a lot for cleaning up imported geometry where the faces aren't quite coplanar - hence the original entities are of little use.

                                Ive had a look through the script and the code is a bit above my head.

                                  Make a backup copy of the .rb script for reuse when you screw-up, or decide the original is better...
                                  Edit the .rb script with a plain-text editor [like Notepad.exe or Notepad++.exe - but never a wordprocessor] and find the lines [~ #104-107]
                                  ### @ss.clear @ss.add(@group) ###
                                  change them to read
                                  ### ents.erase_entities(@ss.to_a) @group.explode ###
                                  This will erase the original selection and then explode the grouped new lines...
