CAD Conversion Services
Our Conversion Service
We convert your paper drawings, Design Build Projects, as-builts and existing drawings into DWG AutoCAD and
MCD, VWX Vectorworks formats. You may submit copies of the original drawings, or send scanned TIF or PDF files
via email.

The documents are 100% manually drafted into CAD. You may choose to mark-out any unnecessary information on
the sheets to be omitted during the CAD drafting process.

All sheets are drafted as full-scale 1:1, dimensionally accurate, layered (AIA layering) and 100% line connections
(no scanning or vectorizing).

Our
CUSTOM SERVICE targets your customized CAD drafting requirements. Submit your in-house layering system,
titleblock, fonts, background CAD files and we will implement them as part of your CAD drafting project.

Our
CONSTRUCTION DOCUMENTS SERVICE allows designers to outsource their CAD construction document
production. Designers can submit their freehand sketches, mock-ups, cut and paste sheets, design development
sketches, along with their in-house customized standards.
LUMINA's staff works closely with all clients to ensure that the final CAD files match the requirements of your
project exactly. Upon receipt of your drawings to be converted into CAD, LUMINA closely examines the project and
works closely with you to ensure that all technical requirements are understood before proceeding with the drafting
process. Before beginning a large conversion project, LUMINA recommends that you send several documents,
along with your specific layering standards, blocks, etc. for an initial conversion. This allows us to work together to
assure you that our conversions meet your specific standards before the actual conversion project begins.

Once you have received and reviewed the final CAD files, LUMINA performs follow-up procedures to verify that the
CAD files have met all of your specific project requirements. If any inconsistencies with the files are detected,
LUMINA updates the files immediately and supplies the updates to your office.

Technical Support
LUMINA follows the steps listed below for convert drawings into CAD file formats and drafting new projects. The
document conversion is accurately performed using VectorWorks 2008 software applications. Below is a brief list of
steps performed by LUMINA.

1. Your original paper or TIF/PDF documents are logged into the LUMINA office. Microsoft Project is used to index,
manage and track all documents and log each step of the conversion process. Your project's special requirements
are reviewed by our staff engineers and architects. These special requirements often include: layering guidelines or
standards; titleblocks; blocks, fonts; hatching; file naming conventions. A technical staff representative will contact
you immediately if your project requirements are not completely understood. A CAD operator is then selected based
on the project type and complexity. The operator is supplied with written detailed instructions fully describing your
project.

2. The CAD operator manually scales the actual dimensions, bearings, distances and coordinates from the original
document and then draws each entity into CAD. During the conversion, each entity is placed on the appropriate AIA
or CUSTOM layer, and any blocks supplied by the client are incorporated into drawing. The result is a dimensionally
accurate, full-scale, layered, AutoCAD (DWG), Architecture (DWG), or Vectorworks 2008 (VWX) (MCD) file.

3. The CAD operator performs Level 1-QA to assure that the converted CAD file matches the original document.

4. The CAD file enters Level 2-QA where the CAD manager plots the DWG/DGN file and compares it to the original
document for accuracy. Errors and omissions are noted and the CAD manager works with the CAD operator to
assure that all errors and omissions are corrected as necessary.

5. The CAD file enters Level 3-QA where the CAD manager reviews the corrected document for 100% accuracy.
Spelling checks, layering standards, file x-refs (when applicable) are verified.

6. The CAD file enters Level 4-QA where it is visually compared to the hardcopy original document. Additional files
are created based on the final CAD file:  PDF-color, PDF-black/white, TIF, CTB (color table files for client plotting).
Once Level 4-QA testing is completed the files are ready to be distributed to the client.

7. The completed electronic files are written onto a CD-ROM, floppy disk or prepared for electronic Internet FTP
transfer or email.

Compression: CAD files returned to the customer using email or FTP are compressed into a ".zip" format. WinZIP
applications are used to compress each file for economical file transfers. For files written onto CD-ROM, the files
remain uncompressed for convenient access by our users.

8. LUMINA creates a package to be returned to the customer. The package includes all documents requested by
the client including final electronic files on media, original hardcopies (if requested), invoice, etc. Upon request by
the customer, the paper documents can be returned or destroyed. Electronic CAD files can be destroyed or
archived by LUMINA for future needs by the client.

Backups: LUMINA maintains electronic backups of converted CAD files over the most recent 5 years. A backup is
created daily and includes:
1) project profile standards
2) TIF images of original sheets submitted by client to be converted; 3) final CAD files; 4) any updated CAD files.
Project data can be retrieved for the Customer at any time

9. Customer Profile Data
LUMINA creates a "customer profile" to ensure consistency across multiple projects. When a new project is received
by LUMINA, the standards, blocks, fonts, titleblocks, etc included in the customer profile are applied to each project.
A customer may also have multiple "project profiles" to handle concurrent projects. Before beginning a large
conversion project, LUMINA recommends that the customer send several documents, along with the specific
layering standards, blocks, etc. for an initial conversion. This way, LUMINA can work with the client to assure that
conversions meet specific standards before the actual conversion project begins.


Layering Standards
CAD layering standards are essential to seamlessly share graphic information data throughout the CAD industry.
Implementation of layers in a CAD file enables better management of visual information.

The most widely used layering standards have been developed by the American Institute of Architects (AIA).
LUMINA automatically uses the AIA layering standards during the conversion of a document unless the client has
supplied their own set of layering standards.

CAD layers are organized into major categories or groups. The major groups are further subdivided into minor
groups. Each group represents a layer in the converted CAD file. Each layer is labeled using a consistent, easy-to-
remember abbreviation. The major groups defined by the AIA include:

A  Architectural     
C  Civil
E  Electrical         
F  Fire protection
G  General
H  Hazardous materials
I  Interiors
L  Landscape
M  Mechanical      
P  Plumbing
Q  Equipment
R  Resource
S  Structural
T  Telecommunications
X  Other disciplines
Z  Contractor/shop drawings

CAD Symbols, Blocks, Attributes
Symbol libraries, blocks and attributes are additional tools designed to better organize the CAD entities in your
converted CAD files. Advantages of incorporating symbols, blocks and attributes into your CAD files is that they
enable you to automatically export CAD data into other report forms. For example, you can automatically count the
total number of door symbols, window symbols, etc. that appears on a floorplan. Alternatively, you can export
floorplan attributes such as room name, room number, area, perimeter, etc. for use with space management
software applications.

At LUMINA, we encourage our clients to submit any predefined symbols, blocks and attributes with each order.
During our conversion process, we then automatically incorporate this reference data into each CAD file. Symbol
libraries, blocks and attributes are not necessary, however, they will provide added control and flexibility for your
final converted documents.

Ambiguities and Data Conflicts
Ambiguities can exist on almost any sheet and there must be conversion "rules of thumb" in place to handle them.  
These rules also ensure communication consistency between LUMINA and our clients. Some of our common
ambiguities and "rules-of-thumb" include: undimensioned original drawings, unclear data on the original documents,
and data conflicts.

Undimensioned Drawings
In cases of converting undimensioned drawings, or drawings with fewer than 20% dimensions shown on the original
documents, our CAD operators perform the following heads-up digitizing procedure:

1. The document is scanned to create electronic raster TIFF image.

2. The raster image is imported into Vectorworks and appears as a background image. During the drafting process,
the CAD operator uses the background as a reference to create the CAD file. The CAD operator manually draws all
entities such as text, notes, title blocks, drawing titles, detail references, schedules, etc. During the conversion, the
CAD operator also incorporates layering, blocks, etc. provided by the client.

3. The CAD operator performs Level 1-QA to ensure the document matches the original.

4. The file enters Level 2-QA where the CAD manager plots the file and compares it to the original blueprint
document for accuracy. Errors and omissions are noted and the CAD manager works with the CAD operator
responsible for the hand redraw to assure that all errors and omissions are corrected.

5. The file enters Level 3-QA where the CAD manager again reviews the corrected document for quality assurance.

6. The electronic file is transferred to Level 4-QA. The electronic file is visually compared to the hardcopy original
document. Once Level 4-QA testing is completed, the files are ready to be distributed to the client.


Unclear Entities on Original Documents
When data on the original documents is unclear or difficult to interpret, the CAD operator creates a "README" layer
in the CAD file. For each unclear entity that appears in the converted CAD file, the CAD operator inserts a "red
box". The red box is an identifier that displays the unclear data. Our clients can then quickly zoom into the unclear
area and make any necessary modifications. The "README" layer also goes through four levels of QA and will
remain after Level 4 QA only in cases where the data was too unclear on the original sheets to convert.

Data Conflicts
Since, LUMINA operators manually redraw each entity shown on the original document, occasionally a dimension
shown on the original document will conflict with the measurement scaled by our operator. In such cases, the actual
dimension shown on the document is used as the default. The scaled CAD dimension is shown in RED on the
"README" layer. Therefore, we can ensure that all of our conversions are dimensionally correct.

Establishing CAD Standards
CAD documents are used by many disciplines and for many purposes. Before beginning a CAD conversion project,
many companies establish a set of internal guidelines to make it easier to reuse drawings for multiple purposes.
Such guidelines ensure seamless communication when CAD documents are created, used, or revised by
employees, consultants or contractors in multiple locations or by other software applications that work with CAD
files. Conversion standards also automatically manage the searching and indexing of large volumes of CAD files.

During our experience in the CAD conversion business, we have observed many different conversion standards.
Given this knowledge base, we have created the following list of 6 recommended standards that you may choose to
consider when developing your own standards.

Drawing Standards
Several primary conversion standards should be adhered to during the translation of paper documents into CAD.  
These standards include the following:

File Name – Drawing Number

To easily identify a specific building or drawing, the converted CAD files should be saved using a combination of the
building name/number and the sheet number. As each document is converted, it should be added to an electronic
index so that it can be quickly cross-referenced and located. The following example illustrates an easy to locate
filename convention:

Format: EJH00101.DWG
Where: E=Drawing Type (such as E=Electrical)
JH=Building number/name (such as Johnson Hall)
0101=Drawing sequence number (sheet number)
01=Revision number or letter


Layering Control
The most widely used set of layering standards was developed by the American Institute of Architects (AIA). LUMINA
automatically uses the AIA layering standards during the conversion of a document unless a different set of
standards has been provided by our client. Each layer is labeled using a consistent, easy-to-remember
abbreviation. The AIA Long Format consists of a single letter Major Group, a four letter Minor Group and a four
letter Modifier. The major groups defined by the AIA include:

A  Architectural
C  Civil
E  Electrical
F  Fire protection
G  General
H  Hazardous materials
I  Interiors
L  Landscape
M  Mechanical
P  Plumbing
Q  Equipment
R  Resource
S  Structural
T  Telecommunications
X  Other disciplines
Z  Contractor/shop drawings

The colors for each layer should be consistent and all objects shall be drawn in color BYLAYER. This means that all
objects assigned to a specific layer should be the same color. Occasionally, the need to create a new layer can
arise in cases when custom defined, or AIA layering standards are not available. Typically, any unused drawing
layers should be purged from the converted CAD document.


Text, Dimensions, Linetype Styles
Standard text fonts are ROMANS and ROMAND. Typically, a standard text height should be defined, however, the
text width should be flexible to accommodate the contents of each sheet. Often, in the case of a crowded sheet it
may become necessary to adjust the text width to properly fit the text on the sheet. The following illustrates a text
style:


Example:   08ROMANS15

Where:     08=width factor=0.8=width of letter
ROMANS=font
15=oblique angle (omitted when set to 0)


Blocks
Blocks are common for repetitive entities that exist on a document, such as doors, windows, toilets, etc. To ensure
that all employees, contractors, and consultants use a consistent set of defined blocks, we recommend that a block
legend be created. This legend should define all blocks. Blocks should be consistent among all drawings included in
a set of plans or a project. For example, if a call-out block "X" is used in one drawing, it must appear as the same
block "X" in all other drawings. Blocks should be created on Layer 0 and then inserted onto their correct layer in the
drawing. When the block is inserted, it should be re-scaled to match the scale of the current drawing. All blocks
should be listed in the drawing index, while unreferenced blocks should be purged from the drawing.


Polygon Layer
CAD documents are often used by other software applications that work with CAD files. Architects and planners
often need facility data such as the area square footage of a room or a section of a building. Whereas, a structural
engineer may need to find the cross-sectional area of a beam. The solution: add a polygon layer to the document.
The CAD operator simply draws a closed polygon over the top of each room and over the entire building. The
polygon layer then enables the export of precise information about the drawing such as room area, perimeter,
location of an object, etc. that can be used with other software applications.
