Layout DWG Exports All Black Background
-
Hi,
I'm trying to export some Layout 3 files/images as DWG format for use in Autocad. Whatever settings I use I get nothing in the Model part of the DWG file and although I can view an image in the Layout 1 tab it is the image on an all black background which is not useful for me. I have read that the Model part is invisible as it is drawn as black on black but is there a similar problem in layout views? If so is it possible to avoid?
Note: Although I am trying to export from Layout, the images in Layout have been brought in from Sketchup. I'm basically using Layout to bring together different views from the Sketchup files. Not sure if this has any bearing on the bug or fix.
Many thanks all!

I filed a bug a while back on this to make vectors white to show up better in model space. It's not fixed. Sorry. I agree.
Yes, your use is what we're shooting for: easily set up a set of drawings by setting up all the views for export.

In AutoCad the drawing area and paper space tab background colours are system settings that you can set in the Options dialog. Background colour cannot be set separately for each drawing file.
The best colour setting for normal lines would be "bylayer", as the lines are exported to layer 0 that already has the colour 7 (white) as layer colour. Colour 7 is special: on a black background, it displays as white, and on a white background as black. Unless you do something with your default printing settings, it always prints black. Using the RGB colour value 0,0,0 forces the lines to always display black.
When I open exported DWG files for further cleanup, the first thing I do is to change the colour of all line and polyline entities to "bylayer". Hatches (that represent faces when I choose to export them) I leave to their original RGB values. I then filter lines according to their lineweights and put them on separate layers (a system analogous to exports from SketchUp).

Many thanks, I've got it more or less sorted now. Turns out I was having trouble getting the images into a vector format ready for DWG export. The model view is still a pain but the layout views of the DWG files are OK and that will work for what I need.
Thanks again.

I find that when this happens to me if I select the black background, a button the image ribbon on Autocad 2011 ADT pops up and says "transparency" you can click it once to enable transparency for png files.
this should fix you up too.

Thanks, Kris, I hadn't noticed that in ACAD 2011. Older versions supported transparency only for 2-bit raster images (tiff, pcx).
This would apply to raster-rendered LayOut viewports that appear as Xref'd images in the DWG exports. If you export a vector-rendered LayOut page to DWG, everything gets converted to native AutoCad objects, and if your standard AutoCad modelspace background is black, you will at first see nothing of the LayOut lines, because they have been assigned a RGB colour of 0,0,0 that always displays pitch black

I'm exporting Hybrids Vector/Raster from layout and I get a good file when I export, the textures come through in the form of a large png file, however when I try to XRef these exports into other drawings I'm getting a "Failed to Merge ISM Image Dictionaries" error.
at which point only vectors come in and I'm forced to separately import the graphics and scale and attach them as best I can...
has anyone else run into this? I looked it up online and found only one post at Autodesk saying the error was caused by a full temp folder or low system resources., but that was not the case for me.
anyone ran into this?
