The micro or detail layout is approached by taking one Space Planning Unit (cell, activity area,
department) at a time and considering it as in independent project. If the macro-layout was done
well, few difficulties will arise.
Product-focused workcells require the most analysis and effort. For these types of SPU refer
to our pages on Workcell Design.
Functional SPUs such as a maintenance department, may require only a list of equipment and
furniture. It then becomes a matter of placing the various pieces within the allotted space
while accommodating traffic and other considerations. In other situations, a process chart for
that part of the process internal to the SPU will be helpful.

Hints for Drafting
The following minimum set of layers is recommended. Beyond this minimum
set, layer management depends largely on individual experience, convenience and the situation.
TITLE BLOCK LAYER--contains
the title block and borders. This layer is off during the drawing activities but should be on
This layer contains column centerlines, columns, permanent walls and other features
that are unlikely to change.
This layer consists of markers or points on (usually) 1' centers. It is most useful when making
prints for installation. In most instances, the installers work by scaling the drawing using the
grid points rather than explicit dimensions.
This layer shows the macro-layout. It can be turned on or off during the detail layout work.
MICRO-LAYER(S)--this layer is where
most objects are placed. There may be several such layers.
Establish Reference Lines
The usual reference line are column centerlines and the inside surface of permanent walls.
They are usually on the original architect's drawings when such drawings are available. If the
building was designed on a CAD system, the CAD drawings are usually reliable. For older
buildings each dimension should be verified with field measurements. Check & double check these
Draw Equipment Templates
Draw templates for all items of furniture or equipment that require floor space. The outside
dimensions of templates should be accurate within +/- 1". Interior features of equipment usually
needs only pictographic representation that suggests the appearance of the actual machine. Store
the templates as blocks or groups within the CAD system. Labels should identify the type of
Most layout drawings have few dimensions. Rather, they are drawn to scale and printed to a
scale that can be measured easily when equipment and furniture is placed.
