          Hi,
          It seems SectionCutFace is not able to map faces if cutted parts are in different altitude.

          Here is the model, I want to cut the top of the walls but all walls extremities are not at the same level.

          and here is the result

            SectionCutFace needs to try to work out what is to be solid and what is to be void.
            If the objects being cut are 'manifold' it's fine, but it there are inter-penetrating forms it can get confused! Give it a helping hand.
            It you choose to keep unfaced edges you can always 'face; these later and apply the material...

              I just installed this plugin and got it to work fine. I want to use it to render a section cut, but when I render with Podium, it renders without the section cut applied. Any suggestions?

              Thanks in advance!

                It does render but the the section-cut is ignored.
                The section-cut-face is there inside the form.
                Use 'Search' for Zorro2 [e.g. http://forums.sketchucation.com/viewtopic.php?p=184604#p184604] - which combined with SectioncutFace - can chop the model along the cut.
                Use a copy as it does physically split the model along the plane and erase half of it!!!!
                Then render the copy model - Gaieus has some examples of a chapel rendered this way...

                    Here's an idea, TIG.

                    Could SectionCutFace be edited to allow section cuts of particular groups/components [hence layers] be created as sub groups and applied to a like named layer? That way the user would have total control over what was visible or not....

                    EG:
                    I have Walls, internal and external, some named demolition and some existing. I cut a section through the floor plan and want to export existing plans, demo plans, new plans, etc so all I do is alter layers in each scene to view existing walls solid fill, demo walls not, etc.....

                    purpose/expression/purpose/....

                      Hi TIG

                      Wicked plugin, and dead handy for my Architecture course!

                      I have a little problem though, i can create section, but as soon as i create a scene afterwards the section cut dissapears. I have tried setting up a scene first and then creating a section cut but as soon as i update the scene it dissapears again. It doesnt seem to get hidden, just deleted? I have tried keeping it locked and unlocked. Is there a setting i'm missing when i save my scenes?

                      I have had a thorough look online and in these forums and cannot find anyone elese who has had the problem.

                      Any help would be great!

                      Marc

                        The SectionCutFace grouped geometry is put onto its own layer.
                        This layer is by default only visible in the active scene-tab, but not in other or any new scenes, but you can switch it on and update the scene-tab[s] as desired.
                        To actually see the section-cut itself [irrespective of whether or not it has a face applied] you need to have it set to be remembered in the scene-tab's settings [Scene Manager]; remember to update your scene-tabs as you change aspects like section-cuts and visible layers.

                          Ah nice one TIG!!

                          Thanks mate, i can't believe i didn't check out the layers! i dont use them much and didn't think it would just turn the cut layer off by creating a scene.

                          Appreciate the quick response too.

                          Thanks again!!

                            By default any new layers you make manually are then active in other [new] scenes.
                            In code you can set a layer's properties differently, so that it only appears in a selected scene[s] but thereafter not in 'new' scenes you make.
                            In this case it is to avoid the confusion of having several section-cuts-faces all 'on' in every new scene-tab, which you are unlikely to want... but if you do want a cut-face on in selected other/new scene-tabs then its layer can be activated in the desired additional scene-tab[s] and the scene-tab[s] updated to remember the changes.

                                If you make your section-cuts inside groups the cuts-faces are only applied to the cut objects only in the context. So you need to have matching section-panes inside different groups and 'face' them individually ?
                                I can't see a way to do it otherwise... πŸ˜•

                                  No worries, TIG. I don't see that working efficiently as there could be many groups requiring cut so multiple section plans requiring individual actions makes it too long a process...

                                  Thought it was worth a try... πŸ‘

                                    Hi

                                    I just downloaded this exciting plugin but I don't know how to use it.

                                    to try it..
                                    I made a cube, selected the section cut and created a section.
                                    I right-clicked on the section cut said "Add Section-Cut Face"
                                    I don't know what parameters to select so I used the default and clicked ok.
                                    Nothing happened. I just got a new layer called "CUT-06737377"
                                    I'd like to use it to Poche architecture plans/ sections.

                                    Can someone please help?

                                      Did you move the section cut into the cube at all? i just ran it on my Mac doing what you said you did and I got the section cut face as expected. Could you post your non-working example?

                                      Here's a shot of my example.

                                        As Dave said you need to cut a section for it to add a face to, placing the section-plane on an object's face won't produce a SectionCutFace - move the cutting-plane into the object even if it's only 1mm...

                                          Great plugin! I was able to use it for one portion of my model, however in another section plane I run the plugin and get no face fills.

                                          Any suggestions on what to change?

                                          I can post a link to the model if that would be helpful.

                                          Thanks!

                                            If you have non-solids, with overlapping 'volumes' sometimes it can't decide which is solid and which is void, so no faces get made.
                                            Repeat - this time 'keeping all edges' [option].
                                            Then you can see what's the complexity you've generated...
                                            and then manually face/color the required parts that you want as solids...
