Noob question: how is the thinking logic of "cut planes" in Inventor? Plz see examples...

By Claudio Zanon on 12 Jul 06:19 8 answers 1 comment

Hi to all here ,especially to those ones working in Inventor. Ok straight to the point on how to do (in Inventor) the sketches no. 3 , 5, 6, and 18 for example of the enclosed attachment.
These are VERY BANAL sketchs : i've tryed using working planes,working axes and point and I'm not able to achieve the given examples.My need is to understand how to cut a solid with a plane "passing through it" in a given point ,edge or surface. Hope you understand the BASIC concept I'm trying to learn...
Thank you very much for some clues on how I can achieve that and sorry if it's too simple,but for one new to a CAD system it could be a very daunting task.
Claudio

    Step 1: Create a rectangle and extrude cut the following triangular shape from the side.
    Step 2: Create a sketch on the front face of the solid. Project geometry as needed to generate the large diagonal line. It should connect to the corners shown.
    Step 3: Create a workplane by using the workplane command at the top out of sketch mode, by selecting the large diagonal line from the sketch, and the face on the opposite end of the solid.
    Step 4: Start a sketch on that workplane and project geometry needed to create the rectangle shown.
    Step 5: Extrude cut the rectangle made away from the solid to create the next cut.
    Step 6: Create a workplane by selecting the 3 highlighted corners in the image.
    Step 7: Start a sketch on the generated workplane. Then project the same 3 points onto the sketch. Draw lines from each point to the other to create a triangle.
    Step 8: Extrude cut the profile away from the solid and that will generate the finished shape.

    Are you making these simply as 2D sketches or as a 3D model and then creating views in a drawing?

    Ok I think I understand. Its a matter of using 2D sketches to create a workplane, and then a sketch for the needed cut on the created workplane. Do these parts have dimensions? If not I can approximate the size and show you an example of how this is done.

    Follow the steps below. I have comments following each image. THis should give you an idea on how to do the others.

    Hi Jonathan! I've tryed both but essentially I start with a 2D sketch making the consequent extrusion and build the next solid and so on...But where I struggle most is to understand HOW I cut a solid with a "plane cut" in a given angle as if I were a "Ninja with a katana"...lol
