I'm trying to explore possible options for displaying 3D geology models. In the attached I want to chop out the yellow solid and leave the other solids "as is" to reveal the various strata when the yellow solid is removed. I have removed the yellow solid but the results are not quite what I was hoping for.
Can this be done?
(I have also posted in the AutoCAD forum but there is so much spam in there......)
I did a quick test which seemed to do what you want. There's probably better ways, I did this:
- draw your 3D layers (I just used boxes)
- draw your cutting object and convert it to a nurbs surface (mine was a sphere as you can see in the pic)
- use the slice command. Select each stratum
- use the surface option for your slicing object
In 3D modelling mode, go to the Surface tab, then Convert to NURBS.
However... I couldn't get it work with a box (as the foundation pad). The sphere was picked at random and I assumed it would work with any solid, however, I think the reason it worked was because it had the single outside surface, whereas a box has 6.
I just experimented some more. What you need to do, is get your foundation pad/box and 'convert to surface' which is on 'Mesh' tab. Then do the slice command, using the foundation pad 'surface' to cut away the geology.
