How to make a rectangular hole at an angle through a body?

[castingflame]

Hi all

I have ben struggling for a couple of days trying to work out how to put an angled hole through a body. It would be the equivalent of extrude at an angle. Please see my dodgy picture below for a better idea of what I mean.

The blue box ends need to be flush with the orange body face and the blue box needs to go through the orange body at an angle.

So far I have tried the Draft feature and the plane at angle but neither seem to work how I want, or I just am using them incorrectly.

Thanks for any help you can give.

the attached show to approaches.

hey try this once

You could use Extrude, or Sweep, or even Loft. But first...

You should decide how you want to control the dimensions of the rectangle...

1. Perpendicular to the rectangle itself, regardless of the angle it takes through the block?

2. Parallel to the face of the block, so that the OPENING is a certain size?

And you should decide how you want the angle defined...

1. As an actual angle or angles through the face of the block?

2. With the two openings on opposite sides being in certain locations, and letting the angle be whatever is required to get those openings in the right place?

The answers to those questions will help determine the method most appropriate and how to set it up.

The size of the hole is the important bit


I would like the far side (destination) to be a fixed position and the origin (nearside) can be moved to the the 10-30 degree angle (unsure of the exact angle at this point).

This is a rough idea of the object that need to go through the hole. Think of it as a 90 degree T piece.



 

At the moment it goes through an object body in a parallel way. The dimensions are just there to show relative positions.





I have some physical fitment problems at the moment so I wish to put the T piece through the object body at an angle. The far side will need to be in exactly the same position but the nearside entry point can drop down. Additionally, because I  need to put the T piece through at an angle, the front face of the body will need to be at an angle too.

I apologise for the poor dodgy drawings, but I hope that there is enough visual information in them to help put my point across.

Thank you laughinggreek for your help.

The problem I was having with the angled plane was that I was not then creating a sketch on the new angled plane!

Even looking at the file, I still do not understand how the other one works or is created. What are the steps so that I can recreate it?

Thanks again.

I used "Plane at and angle" from the construction menu.  selected the short line and inputted an angle.  put a sketch on that plane.

The attached may be closer to what your looking for.  double click on the dims and put in the values you want

re-reading your post, I think you where maybe talking about the other hole.  The first hole I used "sweep" .  The rectangle was the profile and the long diagonal line was the path.  I can see with the updated info you gave that isn't really what your after.

You didn't answer the question in a definitive way. The size of the hole measures on the face of the block, such that the perpendicular section dimension changes as the angle increases? Or the size of the hole measured measured on that perpendicular section, such that the opening on the face of the block changes as the angle increases?

In other words...which pair of dimensions do you want to be the DRIVING dimensions? The pair on the section cut, or the pair on the face?

You can use the sketch of the rectangle to determine your entry/exit geometry of the hole and you use the angle of the construction plane to vary the direction that it cuts through the cube.

Thank you everyone for being so helpful. It is really appreciated.

I'll marked this as SOLVED.

Why don't you just model the object which fits in the hole, then use Combine/Cut to make the hole?

Hi how is this done with compound angles i need to be up 10 degrees and to the left 15 degrees a square box

Simplest method is to extrude your cutter profile, then use the Move tool to position it.
