I am trying to learn a technique for slicing through things in sketchup. In particular I am currently starting a sketchup of a deck I’d like to build. I want the deck surface to run at a 45 angle from the house.

So… I drew a 2×6 in the angle that I want and I make a quick array. Now I have all my boards laid out but they need to get trimmed. I am assuming the way to do this is to draw a plane through the boards where I want them cut and then do an intersect with model.

This is where I’m stuck. I am fighting with it and trying things but it doesn’t seem to be working.

Anybody know of a good tutorial on this subject?

Thanks

Waid,
Have you checked out the Sketchup For Woodworkers Podcast? I was totally frustrated with Sketchup until I watched the first few episodes. I’ve watched plenty of videos on SketchUp, but this guy nailed it!

Thanks Rick. unfortunately I have watched all of his videos and I haven’t seen my issue covered. If I missed it please let me know what show. I think there is only about 7 of them. Now on a slightly humorous note.. I think I might have heard mention of Sketchup For Woodworkers on your show a few months ago.

Well I guess the tool actually does work as I need it to I just have to make sure that all groups are exploded before I try to do this procedure. There is probably a better way.

You need to send a message to DaveR. He’s the MAN when it comes to Sketchup

some pictures of what you have so far might be helpful so we can get an idea of what planes/objects you work with. mind you – intersect only works when you have 2 perpendicular (or angular) planes to one another. any shared lines between them will not intersect.

you seem to have the correct method. where does it fail for you? what happens? and what DOESNT happen?

Yeah, actually, I think I know it because you mentioned it… Wow, how embarrassing!

Well I wasn’t going to mention which episode it was Rick. ;) So Sorry for the unclear question in the post guys. I think all I’m trying to discover is how the big boys do this. I can use intersection planes but all parts have to be exploded first. Exploded parts don’t play nice with the cutlist plug in. It would be cool to find another way.

you can always create components within components and work in “edit-component” mode ;) this way your “boards” stay as boards for arrays, and cutlist.

Wow thanks Dave. I will gladly take your help but I was intentionally not asking you because I kinda feel like you carry ALL the sketchup weight by yourself. But I’m not gonna turn down good advice. I am going to be at my church group tonight so I will be out but maybe we can set something up later this week?

Thanks again.

Here is a pic.

in this case – I wouldn’t even bother with intersecting anything spaids…. just set a guide line at the 45 line, and push your individual ‘boards’ to that line – done deal. 2 seconds and you’re done.

Thanks for the advice guys. You can see in the pic that I already trimmed the boards in this sketch. My issue is in order to do that I had to explode all the boards so the intersect would work. I started by making a board and placed it on the one corner where the boards are parallel to the corner. Then I made the board a component. Once it was a component I made the board a 1/16 too wide. I then did an array to fill the space. I go back and shrink the width of a board back down a 1/16 and since they are components I now have a 1/16” gap between them all. Then comes my trouble. I want them trimmed. Every board is mitered on at least one end. I was faced with trimming each board by hand. My first thought was to intersect a plane. Doing that made me lose my cool components because I had to explode them all. Again please excuse the difficulty I seem to be having with communication in this thread. I realize that I have not been making my request very clear. I’m gonna go back now try to put your (Dave, PurpLev) tips to work and see how that goes.

Thanks again

yep that is the one thing i really dont like about sketchup is that you cant cut components…they have to be exploded. I havent found a way around that, but maybe dave has.

right dave…i forgot about opening the component to do it….though it would still be nicer if we could just draw the plane across all the components and cut it…but your way makes it a bit easier…ill have to remember that for miter corners and such…thanks for all your help and resources!

I second that – see my 2nd post above – you can always work in component-edit mode, which is mostly where I work unless I’m moving components around
