Creating a Radius in 3D Sketching

3D Design Volume Model

Hi all 

 

I need to create a radius between two non-coplanar circular arcs in a 3D sketch but I have no idea how to do it. 

 

Does anyone have an idea? The final goal is to make a sweep following this sketch. 

 

I put an illustration image in the PC.

Hello

 

Sketch leave function...

Edit: oops I wrote without checking sorry, it doesn't work on 2 arcs,

You have to create a spline passing through a point on each arc and constrain it in tangency...

A spline or a 3-point arc, as Coyote says.

However, the points can be located anywhere on the arcs.

 

A little trick to make sure you don't get the wrong plan, the shots are selectable using the "TAB" key.

One solution is to proceed by construction; For example, starting with a sphere that you empty to obtain the desired arcs. Then we make the leave between the 2 sides with the function. Then, we make a 3D sketch and we convert the 3 arcs we are interested in; We obtain the 3 tangent arcs (2arcs + fillet) in space. We hide the sphere.

The 3 arcs can be used as a scan path (see attached image)

Another possibility: close the outline of the 2 arches so that you have 2 planes that touch where you want to make the leave. Then do the leave of the 2 shots.

We then make a 3D sketch where we turn the desired edges.

Hello

 

For my part, I would opt for a three-point arc by adding tangency relations and a radius.

 

A+

You can make a single 3D sketch for your scan, otherwise, you can create a plan to connect your two sketches
