[req] tracing bitmaps?
-
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:
SU after import

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.

wow charly, this looks better. how did you fill the fileds?
-
it is the same in this drawing stray lines and open contours.
-
With the plugin "make faces 1.4"

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 can't find the make faces plugin...
at the moment I'm trying the plan tools http://forums.sketchucation.com/viewtopic.php?f=323&t=30512&start=0&hilit=make+faces

Jo-ke,
if it is not in your Tools menu, have a look here:
Ah thank you. now of course I've found it.

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?
-
Thomas,
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.

The result is perfect!
I've quickly used "make faces"
and pushpull and the result looks like that:(of course many lines (doors, fonts,...) need to be corrected but that is easy with that result.)
