Revit to AutoCAD

[Anonymous]

Hi,

I have been getting Consultants drawings that come from 3D Revit to 2D Autocad

They come with the blocks exploded and on the wrong layers

The drawings are very hard to work with

Is this a normal practice when converting from 3D Revit to 2D AutoCAD, or had the Consultant used the Flatten facility incorrectly

Thanks Mike

Hello @Anonymous,

If you only need is Plan/section/elevation you can directly convert it from revit. It is actually 2D or flatten by this time.

All you need is open the Plan/section/elevation or the particular floor plan level/ew and export to CAD Formats.

You don't have the whole 3D model to export and then extract to 2D model which is very strange and inefficient for taking to much time.

@Anonymous hello, in Revit before you export your Revit Model you have to choose what standard of layer you need it to be. (please see attached)

some objects will be automatically exploded like if you use detail ines, annotation arrow etc. but if it is a component or family for example door, windows, tables, chair..etc it will still remain as block.

"Is this a normal practice when converting from 3D Revit to 2D AutoCAD, or had the Consultant used the Flatten facility incorrectly"

once you export to autocad all objects will be in 2d or flat unless if it is in 3d mode.

thanks

Hi Arjay,

Thanks for your response

This issue I have is that the Revit drawings sent to me have the symbols
on the drawings exploded
Typically an exist light is represented as a bow with solid infill
These are now 6 separate elements and on an a layer called annotated
text together with a heap of other non related exploded blocks

I am being asked to as-built these drawings

So I have to either create a new block and insert in, as well as
deleting the exploded elements

And I need to do this for all the lights, switches, control circuits

So you can see my frustrations

Prior to the popularity with 3D, I never had this issue

I am a 25+ year AutoCAD user

You should contact the source of the drawings and tell them what you need.

Hello @Anonymous

RobDraw is right, You should contact the source of the drawings and tell them what you need.

Agree. They are doing something they don't need too. I've had drawings that I've worked on that were made by someone else that had strange things done to them. Like they didn't know how to go in and change hatch or line weights of blocks so any block they wanted to change they just exploded and then changed the line work. That or blocks with text attributes that they wanted to change the text size. I guess they didn't know it was easy to just change the text size so they exploded the block so they could change the text size. Some of these work arounds seem easier for people to do rather than change things correctly and they maybe right if it is 1 instance. It is bad drafting though and they get in the habit of doing it. Once that happens their drawings are a nightmare for other people to work on. It's mighty aggravating to try and move a section flag only to find it's 25 pieces of linework/hatch. UGH
