Polyline woes

Polyline woes

I am struggling with what should be a very simple and quick operation. I have 200+ frame outlines in a drawing, and I need to convert each of them to a closed polyline so I can extrude them.

The frame profile is made up of around 6 straight lines, four arcs and a wavy section made of around 50 sections made into a separate polyline.

Many of them have worked fine - I have to take great care at the corners and joins to ensure all line ends meet up correctly.

However, I've had a few where the process doesn't work - although a closed polyline is created, it won't extrude. However, if I take that profile into a new drawing, explode it and repeat the process, it works and I have an extrudable profile. BUT, when I take that successful profile back into the drawing, it won't extrude (cannot sweep or extrude a self intersecting curve).

Can anyone advise what is going on please?

 

Many thanks.

u can do it through BOUNDRY  command

enter BOUNDRY

and just select the inner portion of ur polylines.

automatically urlineswill be converted as a closed polyline

Hi,

 

>> However, I've had a few where the process doesn't work - although a closed polyline is created, it won't extrude. 

Can you show that objects (as DWG)? It's difficult to speak about some geometry that does not work as expected without having access to them.

Thanks Alfred. I won't post a dwg now, as Nevil's suggestion seems to be working flawlessly.

Also, I think I might send something that doesn't work in my drawing, but works for you (as it does if I create the profile in a new drawing).

I wish I'd known about this command years ago.

Hi,

 

it's great that you already found your solution! :cara_guiñando_un_ojo:

I would like to have your drawing (erase the other entities) and not a copy of that polyline in a new drawing.

From what you tell us I agree that it might be a combination of drawing + geometry, and that can have e.g. high coordinates as reason, or something else. But again, hard to guess without having it. :cara_guiñando_un_ojo:

If you want to find the reason the feel free to upload it.

 

>> I have 200+ frame outlines in a drawing

Just to make sure: if that geometry objects don't intersect or touch each other, that should be done by just one command (_PEDIT with option "multiple objects).

With _BOUNDARY you have to go for each single polyline, maybe if you know the reason about when that issue happens the result is less work :cara_guiñando_un_ojo:

 

On the other hand .. copying all arcs and lines to a new drawing should also result in running just one single command to get it done?
