I’ve been using this method to be able to have a direct way of producing hatches in my Layout DWG exports.
This is the closest I get into a standard CAD output that other people can use and I’ve been asked to share the process with another user. I thought it would be better to share it with everyone, hoping it might help.
So here it goes…
The following is an example of a model where hatches have been stripped down to color fills (leftmost viewports), so they can export as vector solid fills to CAD.
Unfortunately, you’d still have to fix the DWG’s model space as stacked viewports are everywhere:
Alternatively you could use the Export for Sketchup method, which will stack everything up in model space, but that is rather difficult to use for other people if they want to edit the drawing. So interior designers, landscape architects and even structural engineers, to name a few, might need the standard export method and as, most probably, you will have to use stacked viewports, be ready for having to fix this part.
You have to be careful as if vector viewports produce loops or holes in hatches, these will fail to create the hatch. You can see that happening in the section in the bottom left. As long as you avoid those, you should be fine.
For Layout export to produce solid fills, you’ll have to combine the following:
- Sketchup style should feature shaded faces (no textures);
- Layout viewport should be vector.
You should only use this combination in your stacked section view. Be very careful to use it in your background as it will export all faces as an hatch, into DWG. For instance, if you have a terrain, full of triangles, each triangle will be exported as a single hatch and your DWG file will probably be unworkable.
I still use hybrid rendered viewport in background for clients and contractors.
For permits the background must feature hidden line or flat shaded (all same) Sketchup styles, so that all is vector and municipalities accept my DWF output in an “easier” way.
In my country this will still result in a non standard export. This happens because Layer info for construction elements is not being exported. This Layer info exists in the Sketchup model, as Sketchup Tags, but Layout isn’t able to read tags and output them as CAD layers. No CAD layers, no DWF layers…
This should really be fixed.
