Hi Leila,
Any AutoCAD file has to be checked before linking/importing into Revit file , as this file may has something floating elements/points somewhere in the dwg causing it to exceed the 20 mile radius.
Try the below check points on the DWG file before inserting into your Revit file , and it will be most probably fixed.
TURN ON ALL LAYERS
* TO TURN ALL LAYERS ON USE COMMAND “LAYON”
UNFREEZE ALL LAYERS
* TO UNFREEZE ALL LAYERS USE COMMAND “LAYTHW”
SET APPROPRIATE UNITS
* USE “UN” COMMAND TO SET DRAWING UNITS
CHECKOUT ORIGIN OF DRAWING
* MAKE SURE THAT ORIGIN OF DRAWING SHOULD NOT BE FAR AWAY
FROM DRAWN ENTITIES. (Try to put the drawing at 0,0,0)
DRAWING EXTENT
USE ZOOM ➤ EXTENT TO SEE ENTIRE DRAWING
IF EXTENT OF DRAWING ARE HUGE THEN REMOVE ALL UNNEEDED
ENTITIES TO FIT THE SAME
* MAKE SURE THAT, AFTER ZOOM ➤ EXTENT ONLY REQUIRED ENTITIES
SHOULD BE VISIBLE IN THE DRAWING
NO ELEVATION FOR A CAD ENTITIES
MAKE SURE THAT ALL AUTO CAD ENTITIES SHOULD BE CO-PLANNER
MAKE SURE THERE IS NO FLOATING GEOMETRY IN THE Z-DIRECTION
* USE “FLATTEN” COMMAND TO MAKE ALL ENTITIES CO-PLANNER
DELETE OVERLAPPING ENTITIES
* REMOVE OVERLAPPED CAD ENTITIES BY USING “OVERKILL”COMMAND
PROXY GRAPHICS
* DRAWING SHOULD NOT CONTAIN ANY ENTITY RELATED TO PROXY GRAPHICS
* USE “AECTOACAD” COMMAND TO CONVERT PROXY GRAPHICS ENTITIES TO AUTO CAD ENTITIES
X-REFS
* BIND OR REMOVE ALL X-REFS.
BLOCKS
* EXPLODE ALL BLOCKS (AS BLOCKS INSERTION/CREATION POINTS IFWERE IN FAR EXTENTS, CAUSE TROUBLE IN REVIT)
PURGE AND AUDIT
* PURGE AND AUDIT DRAWING BEFORE IMPORT INTO REVIT
Note:
SOMETIMES WE HAVE TO SELECT THE GEOMETRY AND “WBLOCK” TO SAVE AS A NEW .DWG FILE TO PREVENT FURTHER ISSUES.
(Try to do so always)
