[req] tracing bitmaps?

Hi,

I've tried different options with the plan. This was the best thing I could achieve so far. A professional may be able to get even more.

After I had optimized a bit the image in PS , the plan now looks like this. I do not know whether this is helpful.

the first one looks quite good. I don't have SU8 yet, so I'm not able to open the file.

I think the problem will be after the push/pull function, the walls won't look plane.

But this could be a solution for my carpet problem

Inkscape.org .....Check out this great FREE program...Does what you want and lots more....

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

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.

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.

charly2008

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...

I removed all the stray lines but you can see some of the contour lines are not closed. This finding is hard work. Oh I remembered there is a trouble shooting style.
