NX3/winXp, Crosshatching question

[jackley]

Another question about one of our tedious tasks.

We usually have to add a view on our drawings showing what areas of the part gets bonding. How we achieve this is by expanding the view, extracting lines, back to the drawing and adding crosshatch to the view (using the lines we extracted or silhouette curves the drawing extracts).

This is a huge time sink. We have to redo the cross-hatch a lot, from small minor updates to major updates to the part.

Anyone have any ideas, or deal with this that can maybe shed some light.

Thank you.

I'm interested in an answer to this also. We do as you do, except we put the xhatch in the view.

Yea some of the guys here do that as well. I like it on the drawing so I don't have to expand to the view to update the hatch.

If you have really complicated contoured parts that are bonded, painted or grained over wide areas, why not adopt a standard whereby you extract the region that is affected to a specific categorized layer and nominate where it is to be found in the 3D data as part of the drawing notes. Time comes when you can't see the whole affected area in a single view, then that's what 3D data is all about.

However, with simpler defined areas I might define the boundaries of target regions as curves, especially if edge curves aren't going to be available in the solid model for example. Where we differ is that I'd try to do this in modeling space, on a separate layer from the model. I would create the drawing mostly with just the model visible, and in the view or views where you need to call up the affected regions make the layer with the curves visible, and then use them for the hatched regions.

In order to make the regions very easy to maintain you can try using the join curves command to create a closed boundary, because it will only take one selection to crosshatch. If you create the boundary with curves or lines that you may later wish to change then why not place them on their own layer that stays hidden. then keep the joined curve associative to them. All this may sound somewhat complicated, but it sure is easier to maintain than anything that involves picking and re-picking crosshatch boundaries in drafting.

As for the hatching itself, it lives on the drawing, (i.e. expand member view is not used). Others may differ, but I find this method easy and works for me.
