2D Pipe with fillet

[whosa]

Hi,

 

I would like to draw 2d pipes with fillet corner.

 

I need something works like:

• Pich the center line 
• digit the diameter of the pipe 

 

Right now I use Offset command but it is a bit complicated make the corner "curved".

 

Any of you know some lisp?

 

Thanks

Assuming I understand what you're asking, you could use Lee Mac's Double Offset Lisp.  Draw the centerline, with fillet corner to adjacent line. Then apply lisp and select the centerline.  If you go one step further and join everything you'd only have to select a single line.  Might not be exactly what you're after but if definitely makes things go faster.

Thanks for your reply. I would like to get something like the picture attached (fillet on the vertex of the line), not a simple offset.

Look at THIS thread too .. plenty of examples.

If the centre line has the corners filleted, then offsetting the centre line would give you what is needed.

Yeah, that's what I was getting at.  I think my words might've gotten in the way with my description.

I am sure this exists here already, have a look at lee-mac.com he may have something, google I am positive I have seen this recently. It just asks for vertice points and fillets as it goes. Will try to find for you.

 

OK Fillet Polyline, R, enter radius, pick pline its filleted, then offset, erase original pline.

 

Found some time just pick pline points then press enter.

No worries a pretty easy one. Could be way smarter in its lengths input.
