Very basic question: filled sketches

I have a probably very basic question...

I model with Pro/E 2.0 a lot of ceramic substrates with metallization patterns, and assemble them in optoelectronic packages. I used to employ "cosmetics" to draw patterns for the metallization, but I now find it more useful to use sketches and x-hatch them. The trouble is that when showing the model in shaded view (for example to show the design to a process engineer ecc) the x-hatches of parts behind other parts are still visible. Mind, not the sketch outline, which nicely follows the hidden surface removal, but only the hatching. This turns my models into a mess... Is there any way to correct this?

Putthe hatchon the layer and then hide the layer for that specific view.

This will hide the sketch completely, I probably did not explain well, the problem is that in the 3D view (not in the drawing, I mean when modeling) the sketch fill is still visible through parts that are in front of it and should hide it away. I've seen that in WF5.0 it works like I'd like it to, I'll check WF3 or 4...
 
Let me try to clarify what you want to do so everyone understands. Correct me if I am wrong... Your detailing a place on a part in the part where no paint or grinding needs to occur. Then when you update that into a drawing you upset because you see those sketcher geometries in the non relevant views.

No, no, I'm sorry I had to attach images before, it's not a problem of drawing, let me attach an example of a very simple part:



A simple protrusion with a sketched pattern for metallization pads. Sometimes I need to assemble lots of this ceramics and other substrates, mechanical parts etc but in WF 2.0, when I re-orient the 3d view it looks like this:



As you can see the outline of the sketch is hidden, while the x-hatching is still visible through the geometry. Imagine having more parts stacked, each with its own metal layer, it soon turns out a mess. I often need to look at this parts with other engineers directly in Pro|E, and it's really annoying.

I saw that in WF5 it's correct, that is the x-hatch disappears behind the part, but we are not upgrading to 5.0 that soon so if anyone knows if there's a way to solve this...

I think the problem is Pro/E is treating the hatch as a cosmetic feature. For some reason Pro/E does not do hidden line removal of cosmetics. I see two options, you can put them on a layer and blank them or you can use the view/shade command which gives you a temporary blanking of cosmetics.

You might be better off creating surface patches from your sketches and giving them a different color.

The third option is to upgrade to a later WF release :D Anyway than you for the hint
 
Another option, if you do not actually need the cross hatching, is to create surfaces and color them different from the model. I usually offset them a very small amount to eliminate the color of the model from bleeding thru.
 
creating surface and giving different color is one good option.


if you still wish to go with cosmetics, anouthersolution could be creating two cosmetics one with hatching and the other with no hatching. hide and show each as required. use edge for sketching the second overlaping feature.
