In the following video we show you how best to handle solid fills and or hatch patterns that overlap each other, and how to best draw the plans to get the best looking deliverables.
In TBC Hatch Patterns are transparent, so if you have an area that sits on top of another area, and you hatch both areas with a different hatch pattern the two patterns will be visible in the common area and will look like a dogs breakfast on a plan or PDF output. The best thing is to pick the outer area as an Inclusion and also the inner area(s) as exclusions to stop the outer hatching from being drawn in the inner area. When you have areas inside areas, the order of use is the outermost area is an Inclusion, the inner areas are exclusions, if you have another area inside those then that becomes an inclusion again etc. on an alternating basis. If you have two areas that partially overlap i.e. they cross over each other so there is only a partial overlap that will create ambiguity and you will need to use your CAD skills to create the areas as needed for the purposes of hatching.
The video below shows how Hatches are handled differently to solid fills and provides some simple tips for how to draw the areas before trying to hatch them to get what you need.
Hope the video helps
This second video explores a second option where we can use a solid Hatch at near white (not exactly white (245,245, 245 vs 255,255,255 for RGB) as a Normal Print Priority (to block out a background hatch (on a layer set to Background Print Priority) and then add a third hatch on a Foreground Print Priority Layer using a different hatch pattern on top of the solid hatch pattern. This creates quite pleasing results.
Additional Note: only one of the RGB values has to be off by 10 so you can use 245, 255, 255 and get really close to White if needed.
Let me know how this works out for you.
