Looking for tool to cut non-solids along a plane
-
Could you use the trim command in the solids tool set? You would have to group each set of objects and make each watertight. Once finished ungroup and delete the not needed planes, lines etc... A lot less work than you are currently doing??
-
Love the solid tools, but in this case the individual tiles aren't solids. There's only one curved face. Even if they were solid, I'd have to operate on each one individually. What I'm doing now is quicker than that.
-
Can you post your file in Save as V7 for a more large audiance ?

-
You could give Zorro2 a try. Save your work first.
-
Ok it's more easy when we have the file!
So it's easy
Select only the roof's tiles
Group it
Copy Move it somewhereSelect only the walls
Intersect with model
Erase the "Top" wallsKill the original group
Re put the group copied at the original placeEt voilà!
All take 10 seconds!
-
You can also try Extrude edges by vector to Object by TIG!
-
Forgive me for jumping on this post..
Hi Pilou.
Could it be possible to achieve the same outcome by selecting the tiles and grouping them then with the group selected, select the walls and just intersect with selection? -
Surrely that make the same result!
But not sure you will maybe obtain some lines trimed on the tiles!In the original file seems tiles are yet trimed!
erase all walls for see that!So use tiles without lines trimed!
-
Reading the other answers I'm not longer shure that I understand the question right, but I created a little screencast, so here it is ...

Cutting the tiles at the cut-planes isn't the problem. Any of the Intersect Faces options will work. It's the niggling work erasing the hairy remnants that takes time. Cotty's screen-cast illustrates the problem. Even after aligning with axis, selecting and erasing took him some time. Zorro2's Slice Model at Section options is very nice, erasing everything behind a section, but it can't handle inside areas. Checkout my first screen-cast.
Thanks for all the help.

Ah! Ok! I had not understood that you want cut your roof's tiles!
I had trimmed only the wals !So first : as your tiles are some similar you have way better to make a component!
You will obtain a very more light file!And if by hasard you want to change the model of the tile that will be more easy!
So second: if your model 3D of tile is "manifold" (waterproof) and if you have the Pro version (you have as said your profile) you can make easily Boolean diff with 3D walls!
-
What if you had something like this, at least on the edges where you need to trim solids?

I initially tried using solid tools but opted out because:
-
each tile has to be solid and, and in my experience, solids often get unsolid, for unknown reasons, and the hunt to find the problem eats time.
-
you have to make each cut tile unique, then run the solid tool for each (taking a lot of time). While most of the field tile could be instances of a component saving polygons, the cut tiles would each be unique, costing polygons. I'm not sure if there will be a net savings over my single face exploded tile method.
-
It could be my graphics card (NVIDIA GeForce 750M), but when I rotate the model with a field of component tiles I get lags as the tile field redraws. Rotating a field of exploded tiles is smooth. This is only a minor irritation.
I thought I'd save polygons by using a single face on the tiles. They look okay until you zoom into tiles with exposed ends.
I'm going to give components another try though, now that I've discovered Zorro2. It has the ability to operate on nested components. I should be able to use the slice-model-at-section option to save time, then use solid tools for interior and oddball tiles. I'll report back.
Wishful thinking:
With Zorro2 you can draw a edge on a face of a component which becomes a cut through the component. Pretty cool. You then have to select and erase the parts you don't want. I wish it had the capability of erasing everything to one side or the other of the edge. That'd be very cool. -

Kupono,
I think I understand your problem.....see attached file for an alternate (albeit) still basic option.Essentially........this method uses the "Stamp" function from the Sandbox tool set.
Create "stamps"..."cookie cutters"....errr....or "shears"...in this case I created 3 "cutters" to accomplish the task.....as opposed to a closed/single polygon (think doughnut) that will fail to "cut/shear" as necessary. (clear as mud?)
Once you create a proper "open/individual" stamp/cutter/shear....it is simply a matter of setting the Stamp "offset = zero" and extruding the undesireable geometry away from the desired geometry enough so that you can easily select/delete the same.
I have attached a .zip/SU file...hope it is not overweight.
Best,
Charlie

If you first hide what must not be cut by the section plane, it works fine.

That's very useful to know. Works great.

Charlie, I like this approach. I was able to extrude the unwanted areas down, but no matter what I did I couldn't get the offset to equal zero. I saw on a few older posts that the offset can not be zero so I tried .001 and then .1--neither worked. I always end up with the default 1' offset. How'd you get it to work?

Kupono,
I apologise, I did not notice my input of 0" was not taking.
I now see it forces 1" offset minimum......so now this method requires one extra step per cutter.Simply offset the geometry of each cutter in 1" to compensate for the 1" added back by the stamp offest......delete one edge of the cutter to remove the face of the offset.(no need to clean up the perimeter stray lines)
Best,

Charlie,
Aside the Stamp tool not accepting a 0" offset value, I've been unable to reliably change it to any value. It may be a SU-2013 bug. After some effort I've found a reliable kludge (contradiction?) (see screencast and attached model). What SU version are you using? Can anyone else duplicate this behavior?
Using the Stamp tool is a good solution for my tile trim problem. I'll be using it.
There've been a lot of great suggestions and I've learned a lot. Thanks to all.
