Surface Extend and Trimmed Surfaces

[stevieboy]

Hello All

 

I was trying to extend a surface, so that my tool would not roll off the edge of part I was machining, When I do a Surface extend,

I get.. Cannot extend trimmed edges of trimmed surfaces and when I untrim the surface the surface turns into a cylinder.

Is there any other way to extend the surface to keep the tool from rolling the edge?

 

Thank for your help

Would it be to much trouble to recreate that particular surface to the lengthe that you need?

I have seen that before as well and that what I did to get around it.

Good luck

Stevieboy,

 

Try using the new fence surface. You may have to change the angle.

I though that x could extend previosly trimmed surfaces.

That's about what I thought, I was just hoping for a quick fix.

 

Thank again!

Since I don't have X yet I did not know that but I had a feeling .......

Could anyone help me with this one?!?

I can't seem to trim the 2 surfaces to each other.

Modify > trim > to surfaces

 

It says curves no closed???

But I'm not even given a chance to select any curves...

 

What am I doing wrong... Again!

flycut,

 

Your surfaces flow in and out of each other near their intersection point. Create-Curve-Intersect to see what I mean. That could be causing you some problems.

flycut,

 

I don't know what your tolerance or quality standard is on this, but give this a try.

 

From the top view, you can see where the 2 surfs bleed together. Create-Line-Endpoints a line in the middle of the bleeding area (eyeball it). I'm guessing that line will be about 95 degrees. Make sure it extends above and below the surfaces. Now, trim each surface individually to that curve.

Thanks Thad!

But my surfacing toolpath worked well without trimming.

It was just annoying not to be able to do something that I figured should be simple.

Come to think of it I don't think I've ever successfully trim 2 surfaces together without using curves.
