extract dwg without overlapping lines

[michina]

I exported a file in dwg format without overlapping lines, to have the plants and prospects of the project in autocad but I export a missing file of several lines, in short wrong. by exporting to wireframe the cad file is correct but with countless overlapping lines and therefore difficult to manage...can you help me?
Thank you
Miki

What procedure did you use?
Did you export every single plan?

see the online guide of revit: layers and properties

Hello, and thank you for the answer. the intention is to export the 2d of the individual plans in autocad, in order to be able to make changes. the problem is that at the time of rescue I have a window entitled "export options", and gives me 2 options exported to 1: wireframe 2: removal hidden lines inside a warning says: views exported to wireframe could contain overlapping lines. therefore I carry out in mode 2 but the result is not the desired one (cancel several lines also in the foreground). I forgot... I have revit 2008... I don't know if I can somehow say something.. .
I hope to be explained... thank you very much for the availability
Miki

with revit 2010 I have the same problem, but not only.. .

no one has ever explained to revit programmers that blocks should be created on layer 0 and then placed on actual target layers.

in making layers then create a nice case. to come out to adapt your printing table is a workmanship of hours and hours....

it would be preferable not to export, but when you fall into big problems on revit or steps to autocad or risk not to deliver the job anymore.

yes...the problem is that I am a new sw user so I still don't know how to manage prints and print thicknesses; For this reason, the 3d would have wanted to export plants, prospectuses and sections and then edit them and print them by autocad...unfortunately the work is for tomorrow and I think I won't be able to get out... I will wireframe it with all the lengths of the case...

 

[roberto]

Have you tried to create the printing table in your revit project?

Usually the press is fine. just enter the various views in the resolution you decide, both in the views and then in the print options.

you do not have to choose the thicknesses as in autocad, you do not need to... :smile:

Thank you: I will try!

@ michina
the 2008 version still had some problems in the export of dwg, however it is preferable to export the file in wireframe and possibly from autocad to turn out the layers that do not interest.
during export, revit creates a layer for each family of objects, in the 2010 version also for subfamilies. of course if objects are created and used as generic models, they all end up in the same layer. If you plan to export to dwg, with the need for various layers, in the design in revit you must properly "program" the management of the families, which subsequently will give rise to the layers.
if not erro, even the revit version 2008 had a panel for managing the layers in export dwg

@ rob
version 2010, with the panel : export>port format cad>dwg>propriety dwg, button at layers and properties, allows to rename and set all families and related subfamilies with a specific layer both in name and color.
This table, set and saved is reusable to each export in dwg

thank you so much... even in the ver 2008 I saw that there is everything you wrote... the problem of the confused 2d remains...that is: It is true that I can turn off the layer that I don't care but it is also true that on the layer walls -hipotizzando- there are some overlapping lines that I don't know how to handle, as they belong to the same family; The same speech is worth the windows... before.. it seems even worse... so. the ver 2010 does not present qs problem, right?
Thanks again.. .

gfrank have you seen how many layers to change? an infinity. then if upstream the program decides that a Persian in part is seen on a layer and through a block and in part on other layer with other block is almost impossible to stand behind it. we do not talk about walls, floors and roofs....
the difference between the two programs emerges all... .
thank you anyway for your courtesy! :smile:

 

[michina]

Excuse me... I am the most ignorant about it... but with the ver 2010 they have put remedy to the problem of not exporting hidden lines or not? I'm a little paranoid. .

if you refer to the dwg with overlapping lines to me also happens with 2010. I already thought I wrote it....

As gfrank says by ticking on the esports settings maybe you can fix it.... I can't do it so much....

 

[michina]

Yes, I had read, but gfrank had written the opposite in turn, so I asked for lumi...

I make an example:
the family (object) window consists of various parts, glass, frame, cover, etc.
if in the creation of the family, all the parts I create them in one category of families, the main "window", in the export in dwg all the lines (overlapping) of the glass, frame, cover, end in one layer, and then if I turn off (in autocad) the layer, disappear the whole window.
if instead the various components of the family, they are created with attribution of subfamilies, apputo subfamily glass, subfamily frame, etc. in the export in dwg are created many layers as are the subfamilies, with the possibility (in autocad) to turn off the various layers

Finally, in the creation of a window, I can also create a "projection on the floor" made with only drawing lines (to understand a window type dwg - autocad), in a special subfamily of the main family of the window, after the export in dwg I can leave only the layer of such subfamily, that satisfies the design in autocad style

the "programmer" of revit, has previewed how to manage the export, but cannot manage .... the correct use of the program, or better the creation of families

In fact, you can make same families from very simple... to very complex. using the creation tools ... and this, the revit programmer, can not know ...

Thanks, you were very clear:smile:
