Irregular Surface to Solid Group

[Chris Fullmer]

d'oh, I see you already posted a link to fredo's script Frenchy, sorry for the double post!

[twestover]

Thank you both. I'll be watching for that one.

Tom, I have sent you a version, by PM, that should work with any grouped terrain mesh.

TIG's extrude_edges_by_vector_to_object

recurve the perimeter edges for easy selection then go...

cleanup coplanar edges if desired..

[jeff hammond]

.

also, vector push pull
(part of joint push pull: http://sketchucation.com/forums/viewtopic.php?t=6708)

you can do it with selecting the surface.. use <tab> for options then change to thickening..

intersect with plane for flat bottom..

You can also use drape and Fredo's Curviloft to create that skirt.

First drape the perimeters of your terrain onto a flat plane:

Next select the topo above and the draped shape below

Set the curviloft settings

After some clean-up (and moving the ungrouped top and bottom surfaces inside the curvilofted group) you get a nice solid.

True that my topo has a rectangular outline here but it should work with any shape...

Another cool solution!

Using solid tools for terrain modification. Never thought of that.... Interesting idea.

[twestover]

Thank you all for the creative solutions! sdmitch's solution for any mesh worked great. These others have me loading up on additional plugins.

[pilou]

Can you share the Sdmitch solution ?

[Jean Lemire]

Hi folks.

I did that a while ago for someone who asked the same question. See this SU file for ideas.

The version on my blog does not require a GE terrain patch.

[pilou]

Alas the Drape method (Thx Jean for the V6 don't work at any time without very big cleaning!
JPP vector yes!

Hi Pilou, hi folks.

Try smoothing all the surface before draping to get only the contour instead of zillions of edges and faces.

Just ideas.

[pilou]

Zillions ?
I have 323 entities for the surface and less 80 segments as perimeter!

But Ok with Smooth at the maximum I obtain just one edge alone to close by hand
(not a big deal - the only difficulty is to find it! )

But this will be the same with a bigger surface more sinuous on the edges?
Here I have 2 big straigth lines edges with only 2 arc circles toward inner!

If I have 100 edges to close ?

And after with your method i must make several intersections (just one Push Pull for natural intersection is not sufficient (but not a big deal again

[pbacot]

Another way.

I also thought there was no need to act on all the faces. Here is a complex model. Skirt made with TIG's extrude-edges-by-vector-to-object EEbyVTO. Only problem I have trouble getting all the edges to go all the way to the face (I wonder if there's a lack of technique on my part). So I then pull the face up and intersect with model. (This method seems to choke on an even more complex model, but it might work.)
