      fantastic!!!! a great help for architectural drawings instead of cheap renderings

      thank you

        Neat TIG!! DO you ever get time to work for money???
        This is a little like GOH's 1001Shadows, right?
        http://www.1001shadows.com/en/index.html
        👍

        Not the same thing, this shows shadows cast on selected faces by objects, I don't have that tool but I think 1001shadows projects all onto the 'ground' [of course if you have a ground-plane face selected my tool does the same]. My tool also has options of displaying the shadows - from a line, to a face, to a face with statistics...

        That's pretty cool, TIG. 👍

          Something cool about this but not sure how someone makes use of it. Is it only so you can export a polygon and use it in a CAD rendering (2d)?

            It's as useful as you think up uses for it... 😕
            For example, checking the % of solar shading on some selected glazing at a certain Date/Time.
            Getting the area [sq'/sqm] of perhaps some selected glazing or a solar-panel that's receiving [or not receiving] direct sunlight...
            Because faces using a translucent material don't show normal shadows you can now use this tool to add a visible translucent 'gray' shadow-group face [with no edges] onto selected window-glass etc, to fake these shadows in a Sup render...
            DAE files etc don't contain shadow info but you can now include a faced snapshot of the shadows if desired.
            I only invented the tool - you lot need to come up with uses for it... 😉

              That was exactly what I wanted to experiment: colored glasses and their colored shadows...

              Glasses and bottle are drawn , but 😕 I can't make to "ShadowProjector" draw their shadows.. Probably too complex shapes.

                Simon,
                what scale are you trying at, is it a small triangle issue... just a thought

                  Hi John

                  You are right in the way I never take enough care of the scale !!! 😉
                  In this occurrence, the scale is not too small but too big: a glass of 135cm width !! You may be thirsty 😲

                    Is the orange face 'reversed' - view in Monochrome mode to see.
                    Shadows are only cast onto front faces.
                    Also there is an issue with tiny faces/holes and groups/instances placed exactly onto a face and casting a shadow.
                    I'm doing a fix now...

                                As I can conclude , ShadowProjector not only take in account the geometry casted by the shadowed selected face, but also the entire geometry of the model.😒
                                😕

                                  You are right.
                                  It would be better/quicker if it found only the objects potentially casting shadows on the face...
                                  BUT the algorithm to do that robustly is beyond me [at the moment].
                                  So at the moment it checks everything that's active for shadow casting even when it doesn't even cast a shadow on the face.
                                  So I suggest that keep the 'active entities' simple [using temporary grouping?] and do small sets of shadows...

                                        I can't use the plugin 😞 It crashes my model all the time. I made a magnifier glass and a ground plane (face) . I selected the face, that was oriented with front upwards (the shadow projected on front face), then ran the plugin. ... First time it made a grouped face over my selected one. Now it just crashes every time.
                                        Model attached.

                                          It Bugsplats for me too. 😕 😢

                                          It's a relatively small object and makes many tiny facets in the shadow that it needs to process.
                                          Some complex shapes just have too much geometry.
                                          I erased the unneeded coplanar edges which up the face count considerably!
                                          Also made sure the forms were solids - tiny holes leak shadows - erased unwanted internal partitions and flaps...
                                          The small detailing on the handle also makes some tiny facets when projected.
                                          Lifting the handle up 1mm so it didn't touch the face [a single point of contact or tiny common facet seems to be awkward].
                                          Making it 1000 bigger using Scale, simplifying the handle and putting the lens on an 'off' layer [you don't want it's shadow anyway ?] - I did get it to work eventually... BUT it took ages !

                                          If I copy/paste your geometry into a new SKP I get an error fix now ? message about zero length edges - BUT it doesn't 'fix' within the SKP itself - weird...

                                          This simplified version processes readily without problems.Capture.PNG
