Surface Analysis with Hatches

[Anonymous]

We do a lot of hatching for seeding and blanketed areas. Typically we go through and trace ontop of a (Analysis) of the surface to create the hatches. Problem we have is each time the surface is updated we have to go back and re-hatch or edit the hatch to match the slope analysis. Could there be away we the user could choose a hatch function in the Definition Analysis tab. So the user could still do the normal shaded slope analysis but the option to use a hatch could be there. I think by adding something like that, it will save the users doing Stormwater Pollution Type Plans ALOT of time.

It sounds like a decent idea. 

I even have an idea of how they could accomplish it.  Let the user extract user contours and/or specific shapes created by the surface analysis and MAINTAIN A DYNAMIC LINK so that the object(s) update when the surface changes.  Then allow that element to be used as an associative boundary for the hatch object.

Another possibility:  a lot of these slope analysis options allow you to use a fill color to represent the analysis.  All the user to show a hatch pattern instead of (or even in addition to) the fill color.

You can choose to use a 2D hatch for Slope to save you the tracing. It's in in the Edit Surface style, not Definition Analysis.

Well, I did try it to do what you were saying. And then I took it one step further and exploded the surface and all the slopes are (solids).

Now, I did stumble onto something. If you were to use the surface display of Watershed / then Analysis of the surface; in that dialogue Box you can select 2D Hatches.

No, it's a solid hatch.

I would extract them and not explode..

I wish i could reproduce how you did it, but with 2015 version it is just a solid. I can not perform a hatch edit on it. Plus the solids are all triangles. I had to explode the surface twice to get that result.
