lisp to copy all entities to layer with a suffix

[allanthebruce]

Hi There, 

Wondering if its possible to duplicate all layers (that have entities and those entities) in a drawing to layers of the same name but with a suffix. e.g. _2D and then flatten all layers that have _2D in layer name?

Thanks

Yes, it is possible. Have you tried making a Lisp routine to do it?

HI John,

I don't know the first thing about lisp I am afraid. I work for a surveying firm and we were thinking we'd like to have a duplicate layer of everything in 3d to be copied to a layer of the same name (suffix 2d) but flattened to a polyline in 2D.

Any help is appreciated.

Thanks

Do you need both 3D and 2D in the same drawing? Maybe it would be better to flatten everything in the 3D drawing and then save as to DrawingX_2D.dwg.

[allanthebruce]

HI John,

I thought of that but it would be best in the one drawing.

e.g.

LAYERS

TOP OF KERB_3D

TOP OF KERB_2D

So a lisp to copy the 2D layer as well as all entities and flatten them to polylines.

All layers with elements in one go not just a layer at a time.

Cheers

Contrary to my code of standards, I have an urge to write what you want. I have a soft spot for surveyors. My father was one and I think you guys/gals don't get enough respect or pay.

Are you related to Robert The Bruce? Where are you located.? I'm in NJ, USA, and around here we spell kerb as curb.

Hi John,

Any help is appreciated.

We are moving into the world of Surveying point clouds, using a laser scanner. hence the ability to have both 2 and 3D layers. I'm down under in Sydney. Scottish parents so my mum use to call me Allan the Bruce!!

Any help is appreciated as I know the value of time.

Cheers

Ya know, one of the most brilliant and helpful guys in this forum was Steve
Johnson from Australia. I also made a friendship with a fella named Laurie
Comerford from Australia, who actually came to visit me. I also think that
Rod Laver is the best tennis player of all time.

If I find some extra time, I'll play with this thing for you. BTW, when
you spoke of polylines, do you use 3D polylines, and for what? I wouldn't
think you would want to move contours to elevation 0. Are you using Land
Desktop or Civil 3D?

[allanthebruce]

Hi John,

I know of Laurie he helped me when I use to use LDD I know use Civil3d and we like to use 3d polylines for Virtual Surveying and want to keep everything 3d except for a 2d layer just for the line work for easy measuring and hatching. We always want to keep contours at their true value its crazy how sometimes we recieve files all flattened!!

Agree Rod Laver the best ever, Like don Bradman for cricket!!

Cheers mate

I found an old routine that changes everything (normal AutoCAD objects including attributes) to elevation zero, but I think you want to limit the selection to exclude contours and such, right?  I don't have C3D installed, so I don't know what object names to avoid like figures.  Can you give me a list of exact entity names?

Hi John,

Are you in photo ? Blue or white ^_^

[john.uhden]

That's Laurie Comerford from Australia on the left (in blue) and myself on
the right (in white) in 2001 at my home in NJ.

You are look like friendly, funny and easy going. I like it. ^_^

Sorry for interrupting the story. ^_^

[allanthebruce]

Wow Great shot!!

I guess the entities are LWpolylines and polylines and maybe lines.

Don't worry about contours they are apart of the surface so I don't think they we get selected (civil3d)

Hope this shed some light.

Cheers again mate

It probably doesn't matter but I presume that all the target entities are
in ModelSpace, Right?

You're not going to ask me to dig into XRefs, are you?

Okay, rather than a list of what to exclude, the list to exclusively
include is...
Lines, Circles, 2D Polylines, Text, Block insertions (including
attributes), Hatches, Solids, Ellipses, and Henways.

Please correct me if I've missed something.

[allanthebruce]

Hi John,

No I think you have nailed it.

Cheers

Allan

[john.uhden]

Are you sure about the henways?

[allanthebruce]

Whats a henway?

[john.uhden]

About 5 lbs. 🙂
