Slope Analysis with Hatch Patterns ...

[curt.moreno]

I am using Civil 3D 2009 to do a slope analysis of a surface. And it's working fine. But since my plots are gray scale I would really rather have the analysis with hatch patterns instead of colors.

Is it possible to use hatches instead of colors in the slope analysis?

It won't hatch (other than solid) inside the drawing, but you can set up your plot style table to use a fill style to represent the colors of the different solid areas. See the last item in the plot style list.

Mr. Corey:

That is a fantastic suggestion. Just one more question, if I may. Do you have any idea how to darken and/or change the scale of the pattern that is selected in the Plot Style Table? I have followed your lead but the patterns are very sparse and light. I am certain they will not hold up to reproduction.

You help is much appreciated.

I'm not sure about the scale. For the darkness, be sure the line color is black, 100%, no dither. I'll send Autodesk a tech question about changing the scale.

Curt, I have another solution. If you display the surface slopoes as solid hatch, then extract objects from surface, you can simply change the hatch patterns of those objects.

That is a good plan except that when I extracted the objects they turned out to be "solids" instead of "solid hatches". Consequently I could not change the hatch pattern.

But thank you for your continued suggestions. They are very much appreciated.

I don't think there are that many patterns available through the plot settings but you could:

Use contour banding instead:
Surface level banding would be
-10.000 to -0.001
-0.001 to 0.001
0.001 to 10.000

Now create contours instead using the same data banding, this will create boundaries that you can hatch between, unfortunately not dynamic and not a quick method. I haven't tried but maybe if you use the flatten to zero you may be able to hatch between each without exporting?

Or: You could edit your CTB to use grey scales and vary the darkness / lightness and screening to suit (dark is low light is high? which would be a better option on large variations of levels.

Mr. Corey:

I figured it out. I went to the Analysis tab of my Surface Style and was able to set the Display Type to "hatch solid". Thanks again for putting me on the right track!

Hi Curt,



I have written a short lisp routine that will change those solids into the pattern and hatch scale you specify. If you want a copy, let me know your email address and I'll send it to you.



Best regards,

Hi! all,

In a same way, when i want to show difference between two surface it shows solid hatch but could u help me if i need to show hatching in different pattern may be Iso hatching.

Finally i don't need solid hatch. I need userdefined hatch in analysis view.

Thanks

Dear Curt,
Could you please send me this short lisp routine. So that i will check for my problem.
My email address: shailesh.mane@neilsoft.com

Thanks,

Tim,

I would appreciate a copy of the lisp routine you created that will allow me to use a hatch pattern with my slope banding areas rather than the solid colors as well.  Please send to smorin@loucksassociates.com when you can.  Thank-you in advance.
