Having some troubles putting a straight groove on a angle
-
I used Push/Pull. I pushed up from the bottom. After hitting the fold line in the side, I hit Ctrl (Option on Mac) and pushed up again well past the top. I selected the geometry and used Intersect Faces to create required intersections and then deleted what wasn't needed.
For things like this I find it useful to think about drawing the volume of space a cutting tool would need to pass through to make the cut in reality.
I redrew the model to get rid of the diagonal lines on the sloped sides. I don't know if that is correct but what I did to create the slot would work on your model as well.
-
Sweet thanks, I will give that a try. Yeah I am not sure why those diagonal lines showed up? I am quite a newb at this, just learning as I go
-
The diagonals are there because the four outer edges aren't coplanar. It probably has to do with the method you used to draw the thing. If you have the original to measure from (is there an original?), it may be that yours is more correct than mine.
-
Me again...back from the dead. Forgot about this and sketchup for the longest time (six months) and I am failing hard. Again. First off the upper edges are messing me up. Why are they not coplanar? I want the two angled side pieces to be on the same plane at the same angle? I think they are not currently... and I can't for the life of me figure out how to do that?
I think once I figure out that I can figure out the gouging out part. I did that once by accident but it made me realize how messed up the angled edges were
-
The upper sides can't be single faces because you've got the edges at the ends at different angles. Since the top end edges are the same length but different heights above the waist line, the sides must be at different angles. Decide what else you'll change to make the angles the same and then you can have a single plane on each side.
-
First off...fastest and most helpful forum ever.
Second off: I can't believe I didn't notice that. Of course simple geometry dictates that they can't be on the same plane!

We try.

Uh, yeah. I was about to edit my previous post to include that. You were butting heads with Euclid or one of those other old, dead guys.
Notice with the geometry straightened out, it works out pretty.
-
So what did you do there? Bring the "front" (taller part) "waist" down? Thats what it looks like.
I need to keep the top part level and at that angle...and have at least from the "waist" up tapered. But if that taper starts lower down in the front I don't think that would be a problem...hmm...
-
Nope that ain't working...make the back skinnier? Will try that...
-
I made the horizontal edge at the higher end narrower to keep the same angle on the sides as at the lower end. I also revised the interior to eliminate the same issue.
-
Ah yes of course...Thank you SOO much. This 3d drafting stuff is tricky
-
Makes you wish you'd paid more attention in high school geometry, doesn't it?
-
That was awhile ago...haha
-
Hmm...that one you made. Why isn't it symmetrical? From the top corners to the vertical axis it is 3.3 and 3.7mm? The two slopes are different angles? Man this this is confusing me hard haha
-
All I did is use the angles you drew at the shorter end. I didn't change them. You had the angles different to begin with. What angle do you want them to be? Or maybe more to the point, what are the critical dimensions?
-
I am more of a noob that I thought haha. I gotta go back to the drawing board I think. Slope should be equal on both sides. Only a couple mm's on each side. But I will have to whip out the calipers and see what is what
-
Maybe it is time to start fresh with a new SketchUp model.
-
Yep that is what I am thinking. But first...supper time
-
Maybe it'll make more sense on a full stomach, too.
