slicing object at an angle

[Anonymous]

if I design a rectangle thats 40mmx20mm and extrude it to 50mm then slice it to be flat on the bottom and 45 degree angle on the top. The top or face that was sliced at a 45 degree angle will not be the dimensions of 40mmx20mm it will be larger. Is there a special function or math formula weres i can get 40mmx20mm face dimensions thats at the 45 degree angle.. thanks

Does this work?

You don't say which leg of rectangle is 45 degrees relative to the base.  You'll get two very different shapes depending on whether you choose the short side or the long side.   Use the pythagorean theorem to determine the length of the base line for whichever one you choose (assuming the entire top is at an angle).

I will upload the design once I get home from work today..

Math is fun.  and there are all sorts of formulas you could set up to do this.  but I would suggest just letting fusion do the math for you.  here is a screen cast of one approach.

Need it to look like this, but have the top face dimension the same as the drawing. NOT at 45 degrees but at 30 degrees . file in attachments

a little tricker, but I would still let fusion do the work. projecting from a sketch that is on an angled plane to a sketch on an origin plane does the trick.

(i made a selection set in the screen cast because you can only pick one curve at a time when selecting for project.  turns out that double clicking will select an entire chain, so that step wasn't really necessary.)

So between this question and the first question, I think you want to place a Led on both ends of the spacer, 

Cutting a shaped block won't do it, due to the bolts being square to each face.

So I think you want something similar to this one at 30 deg, but any angle is doable, 

Might help..

If you want the angled face to be identical to the bottom face, the easiest way is to use the loft command. 

1. Start by reviewing Rule #1.
2. Create a new component(1). (Give the components meaningful names instead of (1).)
3. Move Sketch1 to the component(1).
4. Copy/Paste New the component(2).
5. Using the Move command, rotate the component(2) 30 degrees and move it horizontally along the Y axis.  You'll need to set the pivot point to a place where one of the move arrows is aligned with the Y axis.
6. Loft between each components' Sketch1 (excluding the mount holes).
7. Extrude the mount holes from whichever face you want the holes normal to.

Note: You'll need to verify clearances for the led.

And a but more thought can make it look better.

"this is my dwsign now were the 30 degree cut is a bigger opening then my designthis is what the led light looks like inside the opening that fits the led perfect, nothing rong with this design except i font like how the spacer is angled down ward, i want it to look flat like the last pic.This is how I want it to look when mounted. as you can see the angled part is bigger then my desinged drawing. the screw holes im not worried about cause i can make a 30 degree wedge, to act like a washer on the screw head to make in attached straight. This will be mounted on the outside of my camper.

So it's full circle, the answer in the other thread, is what you want,

Through holes are square to the camper, but the sketch is rotated to 30 degrees from the camper face.

Adjust the Plane 1 for the down angle.

Adjust the depth of the Plane 2 for height / length.

Project the shape (Patch Body) of sketch 1 (I made a Patch Body to save all the selecting) to Sketch 9, and

Extrude to the Plane 1.
