Where the project is too large for the title sheet, the drawing is to be split only for

plotting in layout or PAPER SPACE. All CAD drawings MUST be drawn as one

continuous and uniform plan in MODEL SPACE.

All drawing entities for each drawing are to be contained in one file, without the

use of external reference files. If drawings were originally created with externalreference files, the AutoCAD BIND command MUST be used to include the

external reference file as part of the main file. The BLOCK created by this

command shall be EXPLODED.

Layer names from external reference drawings shall conform to the layer naming

requirements as specified in section 3.3. Any layers that have been inserted to a

drawing after an external reference has been bound and exploded MUST be

renamed to remove the external reference file name prefix off the layer names.

All drawing entities are to be drawn in MODEL SPACE on the CAD files;

drawing title sheet information will be accepted. This can include scale bars, north

points, general notes.
