Project Geometry perpendicular to sketch

[mechamania]

Hi,

I have an existing sketch and a new sketch onto which I want to project some lines from the existing sketch.

The panes of both sketches do not run parrallel.

Normally a projection is created by imaginary projection lines from the existing sketch to the new sketch perpendicular to the new sketch.

But now and want to project the existing sketch with imaginary projection lines that are perpendicular to the existing sketch.

Is this possible?

Can you post an image showing what you are describing?

Normally you would use the project geometry command to keep the relationship, but it almost sounds like that wont work.  You can also copy from one sketch to another (copy/paste).

Are you looking to keep the relationship between sketches?

I'm sure there's a better way and JD will probably be along with it shortly, but one way would be to extrude the first sketch geometry as surfaces and intersect them with the sketch plane.

I want to project the sketch on the bottom along the Z-axis (thus perpendicular to sketch) onto the pane above it.

See attached picture.

Hi mechamania,
Can you provide a screen shot or example file?

I'm just guessing, but I think using a 3D sketch and one of these tools might be the answer:

3D Sketch From two planar curves

I hope this helps.

That was my first thought as well - either surfaces or a solid, and then Project Cut Edges would get you the whole thing.

It may be cleaner, though, to make work axes perp. to the original sketch for key points and use new lines in the new sketch to connect the dots - that typically gives a pretty stable result.

My thoughts are to take parts of most of the responses and that is to create the plane(s) and axis (if needed)

and some construction geometry possible using the project gometry command at key locations.  Then like I said in my first posting copy the first sketch and paste it into the second.  Constrain it to the key locations and it should give you what you are looking for.  Make sure you fully constrain the first sketch so that when dropped into the second it doesn't go screwy on you.

Hope this makes sense.

Hi mechamania,

From your PDF it looks like the cleanest way to do this and keep things associtive might be the 3D sketch. But it looks like earlier I didn't post the correct link for the option you want to use:

http://wikihelp.autodesk.com/Inventor/enu/2012/Help/3320-Show_Me_3320/3321-Show_Me_3321/3538-3D_Sket...

Attached is an example file as well ( I didn't see a version listed so I've created this in the earliest Inventor version I still have, 2010).

The other suggestions should work as well.

I hope this helps.
Best of luck to you in all of your Inventor pursuits,

That would be my solution.

Thanks to all for the suggestions!

The projection to 3D skecth worked best for me.

I need the projected sketch for a new extrusion. But it seems you can not extrude from a 3D sketch. So I had to project the 3D sketch onto the pane first. But it works fine.
