Cutting along one side?
-
I need a plugin that can intersect an area/object with another selection and then cut it into inner/outer groups. (or perhaps just delete the inner/outer section).. any advice?
-
Have you tried the Solid Tools?
Your description is rather vague. If you'd at least post a screen shot of what you're trying to accomplish, you might get some additional guidance.
-
Cut to plane, split to plane - TIG's great plugins.
-
Thanks smicha.
Dave R: Split/cut-to-plane is like what I am looking for... instead of a plane I would like to cut with an arbitrary surface or maybe 3d object intersection instead. I'll take a look at Solid Tools.... looks like this is possibly what I need.
-
I tried Solid Tools, but the problem is that Sketchup is complaining I don't have solids. If I could just cut out everything from the inside of the object...
-
Maybe you need to make solids.
-
Well, that IS the goal, but instead I have something other than solids: notasolid.skp
-
is it your wish to cut the lenses with that wave shape? You need to group that shape and then close off the ends.It will be solid. you need to explode the components so the solid groups are in the same context. that will work. If you want to also have the remainder of the lenses, you should first ( before the first trim) duplicate the whole mess, make a negative solid of the wave and trim the opposite side of the lenses.
-
It didn't seem to work before, but I will try again..
-
What is it you want to keep and what is doing the cutting?
It only took a few seconds to create solids from your shapes.
-
I want to keep just the outside mesh. How did you do this?
-
So you want the large "wave" surface with bumps? Or with recesses?
I'll make a list of what I did to make the solids.
-
The bumps, only. Basically everything you can see on the outside of the object.
-
To make the components solid, I deleted the inner components for the "bumps" and also removed the internal face. For the larger component I just added end faces to it and pulled the bottom face down temporarily to get rid of the sharp edge at the bottom.
After that you should be able to use Solid tools to trim the bumps with the large component. You'll also need to deal with the bumps that touch each other, too.
I don't know what you are expecting at the lowest bump so I didn't push the bottom face back up flush. You'll notice the completed shape is also a solid group.

Nice...

But, how did you delete the inner components of the bumps? That is what I am looking to find out!
-
Your original "bump" components contain two components or groups (I can't remember which they were) which I exploded. There was an internal face down the center of the bump which I deleted. this made the bump components solid. I made the large shape solid by putting faces on the ends. Then I used the large shape to Trim the bumps. This got rid of the inside part of the bumps for me.
After that I exploded the bumps one at a time, cut the resulting geometry, opened the large component and used Edit>Paste in Place and then deleted the unneeded internal faces under the bumps. In order to get at those internal faces I hid one end face of the large component. I watched Entity Info to make sure that large component remained "solid" throughout the process, which it did.
-
I tried to do the same thing, using intersect-with-context, but I was unable to intersect some of the areas. Not sure why.
"Then I used the large shape to Trim the bumps."
?
-
Before you used Intersect, did you place the bump geometry in the same context as the large shape?
I used the Trim tool from the Solid Tools set.
It seems to me that you might benefit from starting with some much simpler geometry to learn how to do all this stuff.
-
I exploded the whole thing. It just got real bad. Will try again.
-
Did I say to explode the whole thing?
I exploded the bumps one at a time to make sure I didn't have an issues with lots of geometry.
As I said, I think you try a similar but much simpler version first to learn how to do it.
