Drawing Multilines ?

[Rass]

Hi All...

Many thanks for the reply to my earlier posting.... I need more info on the multiline...

In Microstaion I am able to set a multiline ..say with 10 lines, each line I can specify colour, style, thickness etc.. and importantly which layer each actual line is placed on.... So one multiline can actually, regardless of what layer I draw on, will automatically put its component lines on the layers I specified at the creation of the multiline, thereby giving me total flexibility and control of lines within a ' external cavity wall' which has all its finishes on on elayer.. the actual walls on another layer... etc. etc.

How do I achieve same functionality within AutoCAD ?

Lisps I think. Post this in the AutoLISP topic forum and maybe some genius such as FUCCARO will create a cool wee lisp for YA.

Hmm, although you can control the colour and linetype of the various multiline elements, it seems you can't have different elements assigned to different layers. In a sense this is logical since multilines are single objects and in AutoCAD, single objects can only be on a single layer.

Maybe this can be overcome with LISP but somehow I doubt it. I suggest that a way forward might be to create a compound multiline (multiple multiline styles) and draw one over the other. Not neat but it would work.

It is possible to write a routine to create a copy (or more) of an entity –polyline-, and place it on a specified layer (or on layers specified in a list). Setting in those layers the line color, linetype as you wish, the object placed will have this properties (by layer). But how if you need to edit this entity? You will need to go to every layer in part and make the same changes.

Hmmm seems a lot of work arounds for this functionality....

Perhaps I am looking at the wrong tool... I use multiline tool in Microstaion to draw all types of walls, and the multiline has all componenst of a wall from plaster finish all the way to insulation etc. I turn of the necessary levels depending on the published drawings... to edit this, I just redifine the multine style or exchange for another ml line.

Maybe iN autocad there is a different way of achieving same without using the multiline tool ?

So... how do Acad users draw walls with all their componants and on their respective layers ?

[Mr T]

What about creating a custom linetype ?. It may be inacurate though. There is a neat tutorial on www.cadtutor.net on this.

I think it's true to say that this type of thing is almost always done using an architectural flavour of AutoCAD such as Architectural Desktop. You have to bear in mind that Vanilla AutoCAD is just a basic ( :lol: ) drafting engine.
