3D Sketch on custom workplane?

[Anonymous]

How to snap a 3D sketch to a custom workplane? I know how to snap to the ordinary work planes for XY, ZY or ZX but if you have a plane 45 degrees between these plane how to snap to that for example?

Can you provide a shot of your sketch and what you're trying to do?  Can you place a coincident constraint on the endpoint of a sketch line, to the work plane?  Hard to say what you need to do, without knowing what you WANT to do.

I need to make a frame to the motorcycle. Starting on the blue plane.

When I have the picture up I cant ask how to make a shell of a FreeForm as well?

Looks to me like it should be a 2D sketch.

Attach your *.ipt file here.

The frame should start on the blue plane, continue on the XZ, go down on YZ, back to XZ and then back up to the steering pipe thing (what do you call it?). Maybe I split the tube somewhere but the sketches will go over more than one plane and I be surprised if any plane will be exactly on the standard plane, XZ, XZ or XY.

Why did you attach another picture?

I know what a bike looks like.

My bad.

An assembly file (*.iam) is only a list of hyperlinks to the part files (*.ipt) and a record of assembly constraints (and a bit more).

You must include the part files.

Thorped01,

1. Open the assembly
2. From the Application menu, hover over Save As
3. From the Save As flyout select Pack and Go
4. Copy all the files to a new folder (I suggest a folder on your desktop)
5. Compress the folder of files and post to this site.

You can skip styles and templates when running Pack and Go.

Good luck.

Regards,

Jerry

I did this for example. Think as it like I want a line on the first plane, then it bends over to the next and so on. I just don't want the line to tangent the planes, I want the line to have at least two points on each plane.

I do not see any purpose for all of these Work Planes and Work Axis.

Looks like I am going to have to work up an example completely from scratch.

It seems to me that you're talking about a 2D sketch rather than a 3D sketch. I've looked over this thread and I'm a little confused about what you're trying to do. If you're putting a 2D sketch on a plane other than an origin plane, you simply select 2D sketch from the 3D Model tab and then left click the desired work plane. If you're trying to snap 3D sketch line end points to a plane, you select 3D sketch from the 3D Model tab, then (assuming you've drawn a line) you select coincident constraint from the 3D Sketch tab, then select an endpoint, and then select a plane. The two should snap together assuming that the end point is not already fully constrained.

Does this explanation help?

What I am trying to say here is that yes I can have a lot of 2D sketches BUT i having a lots of trouble making a frame with more than two sketches and i find the bend between the sketches hard to do. So what I do think might solve this is making one single line instead of many and then I need to use 3D Sketch.   

I cant "pack and go" the topic file.

That helps.

Sound like you want those 2D sketches to place the points (there are other ways to plot them but that will work) then a 3D Spline to connect them together.

See attached.

Is this what you're trying to do?

The thing with the motorcycle is as well that I want the pipe to be offset the fuel tank and the risks with spline is that the spline itself goes inside of that offset if you using points. How to make a 3D curve go in to an offset curve and transform in to a spline after that, all in very precisely dimensioned planes I don't know. 

Good night!

I think I know how to do what you're trying to do but it'll be tough to explain in words and I won't be at my desk again until Tuesday. Maybe someone else can show you how to make a 3D path from an intersection curve of two surfaces?

If nothing else, you could still do this as a 3D spline and just fully dimension the points and manipulate it until it looks hoe you want it to

You didn't supply much information in your attached file - so the attached example is only the quickest of efforts.

Sorry to all, I've lost the problem. I guess my Idea where to make 3D sketches without need of 2D sketches on specific planes but I simple played around for some time and got used to the fact that it doesn't work that way.

You can do 3D sketches without 2D sketches - it is just more work and when you get done - much harder to edit, so be sure to get it right the first time.  That is the point 2D sketches are easier to create and easier to use to control the resulting 3D sketch.
