        I thought there were size limitations in Inkscape, ie pixels/ resolution? Has this improved? I will check if I can.

        I take the slow, deliberate approach in my aimless wandering.

          Hi 3eighty,

          I have Inkscape for a while, but I have not worked much with it. But it seems to also not bad and it is free. The problem in both programs the result depends on the quality of the bitmap.

              Hi to Everyone,

              I have drawn a simple rectangle in SketchUp and this exported as BMP. With this BMP I experimented in both programs. From Vector Magic I received a double rectangle instead a single rectangle and from Inkscape I received a very different result. While the image edges are represented as single line or vectors.

              I have less experience in vectorization of objects and I do not know if I'm doing something wrong. Are here in the forum experts who are familiar with this procedures? I would be very happy if someone could help and explain.

              Charly

                OK here is my rug-problem! It's a different situation but the same problem:

                I am drawing the designs of my rugs with photoshop or coreldraw. If the design is a bitmap I can trace it with coreldraw and I can save it as a dwg file. unfortunately the vectors are not filled when I import it to SU so I can't use the pushpull function

                coreldraw:

                  I used the same method with the floorplan

                  vectorising in corel X3. it was a quite good result, the tracing function in corel is very good. no postprocess, export as dwg, import in SU and no filled fields...

                    Hi jo-ke,

                    there are many stray lines (plugin) . they have to be corrected manually.

                        it is the same in this drawing stray lines and open contours.

                            I removed all the stray lines but you can see some of the contour lines are not closed. This finding is hard work.

                            And surely that isn't usable as a working model, is it? There isn't a single straight line there...

                                        Thomas,

                                        I have found now a plan with a resolution of 3335 x 4151 pixels. The result is good. But what I still do not understand is that double lines are generated.

                                          Ah, it create a line for each side of the black pixels... is there a setting for that in the app you use?

                                            In Inkscape I did it. The error was to use the edge detection. You have to use Brightness cutoff. Well, at least most of the lines are individual lines. Please have a look into the attached file.
