AUTOCAD MEP २००८-STEP BY STEP GUIDELINE TO WORKING WITH ABS-ELECTRICAL

AUTOCAD MEP 2008
STEP BY STEP GUIDELINE TO WORKING WITH ABS-ELECTRICAL

THE NEED FOR A PROJECT MEETING BEFORE THE COMMENCEMENT OF YOUR DESIGN CANNOT BE OVER EMPHASIZED. IT WILL IN A GREAT MEASURE ENSURE THAT EVERYTHING RUNS SMOOTHLY AND WOULD HAVE ALSO ENHANCE A TEAMWORK SPIRIT IN THE COURSE OF THE PROJECT.
STEP I: HAVE YOUR PROJECT DESIGN MEETING
There are three common ways to start new drawings. The first is to copy and rename a drawing from a recent job that is of the same type as the new job. The second is to create a prototype job setup containing drawings with externally referenced borders and office-specific or job-specific styles. The third is to use a template with standard text and dimension styles set up in the drawings.
Templates let you implement consistent standards, reduce errors, and increase drawing accuracy. Autodesk® Building Systems includes templates that let you start drawing right away. This chapter looks at the templates in Autodesk Building Systems and the settings that create your drawing environment.
STEP II: CREATE YOUR ARCHI BASE PLAN

1. Open the architectural drawings, go to the Project Navigator Palette construct tab, rightclick the already create folder for Architectural base plan and select “save current drawing as construct.”
2. Fill the project dialog box that appears
3. Confirm the template is the right for the discipline.
4. Close the dialog box
5. Clean out the drawing by removing landscape features and freezing features like dimensions. There may also be need to correct some improperly named layers.
6. Turn all layers to grey.
7. Save your drawing afterwards.

STEP III: X-REF YOUR ARCHI BASE PLAN
1. Select and open the electrical file (construct) you want to work on.
2. Go to the archi base plan construct you want to x-ref, rightclick, scrow down and select “xref overlay”


IV CREATE YOUR ELECTRICAL WORKING ENVIRONMENT

Go through the following steps to create your electrical environment and save your result in the template to re-use.

STEPS 1

1. From the first electrical dwg file opened and if not select to open.
2. Scroll down the format menu to select the Option command
1. Go to the Profile tab and select for Electrical-building engineering tools extention-metric uk confirm that the template file is “abs tools model (metric.ctb)uk” this can be quickly confirmed by right clicking the category folder to select a new construct. Read the default template. Amend the template when necessary. See volume 1
3. Scroll down the format menu to select the Drawing set-up command-a dialog box appears
4. Select unit tab, select millimeter for unit and 2 decimal places.
5. Select scale tab, select 1:100 for default and confirm annotation plot size to be 3.500000
6. Select layering tab, confirm layer standard to be pointing to- C:\Documents and Settings\All Users\Application Data\Autodesk\ABS 2006\enu\Layers\ABSToolsLayerStd5.dwg. Otherwise, review.
7. Confirm the layer key to be BS1192 Descriptive (256 colours) ABS TOOLS
8. Apply and select ok








STEPS 2

1. Set your Electrical Preferences:
2. Scroll down MEP common to Electrical, under which you scroll down to Electrical Preferences- a dialog box appears
3. Select Voltage definition tab and fill as follows:


Items Description Voltage optimum(V) Voltage min (V) Voltage max
(V)
1 1-pole 240 200 240
2 3-pole 415 400 415


1. Select the circuiting tab
2. Under circuit naming, don’t select “required unique circuit names per drawing”
3. Under prefix select Panel name
4. Under numbering select “use sequential numbers”
5. Under overload, select ”display overload in circuit manager”
6. Under “warn when load is,” select 80 % of circuit rating.
7. Under wire sizing, select 30 degrees for ambient temperature
When the distribution panel had been created on a different drawing,
8. Select project database tab
9. Point to the file location of the distribution panel









Set your elevation for various electrical fittings to be installed

1. From format menu, select Options and scroll to ABS Elevations
2. List the various elevations and the corresponding values.
3. Apply and select ok.

Save the drawing file and also save as a template in the template file location named as CACL Electrical Template:check that the file extension reads dwt.
ALSO save as CACL Electrical standard in the Standard format:check that the file extension reads dws.
NB:You will be prompted to save at some unique file location. Change to your choice where necessary
Establishing standards to guide you through a project design is recommended at the beginning of any project. Standards, generally referred to as CAD standards, enhance efficiency, maintain consistency, and automate repetition.
Templates can be a powerful tool as part of your project standards. Templates store the following standards required to begin a drawing:
1. Unit type and precision
2. Drawing and plotting scales
3. Dimension and text styles
4. Layer structures
5. Linetypes and lineweights
These additional design-specific standards can be established on a drawing-by-drawing basis or added to a template:
1. Design and drawing preferences
2. Coordinate systems
3. Design and plotting display layouts
4. Title blocks and borders
Autodesk® Building Systems, together with Autodesk® Architectural Desktop 2006, provide a variety of tools to assist in configuring, working with, and managing standards. You can create standards for any of the following:
NB: The standard file becomes the start-up point for all electrical services drawings for the current project.

WORKING WITH STYLE MANAGER-ELECTRICAL SYSTEM DEFINITION
Properties that remain constant for all parts within a network of connected parts are stored in the style manager.
After you become familiar with Autodesk Building Systems, you will probably create your own templates based on your office standards and projectspecific standards. When using an office template, you can import styles from another template or drawing using Style Manager. Style Manager provides a central location where you can modify styles, create new styles, and
copy styles to other drawings.

Firstly, explore the following folder ‘enu’ to see various items(folders and files) and there location. Here you will find the template folder, the layer folder, the AEC Content, Aecb Content, Details, Plot Styles, Styles, Textures, Aecb Catalogs, Aecb Shared Content, Layers, Plotters, Tool Catalogs.

The path is as follows:
C:\Documents and Settings\All Users\Application Data\Autodesk\ABS 2006\enu







The following steps show how to import the wire styles from an external drawing into your current drawing.

1. Select style manager from the format menu drop down.
2. Explore the various icons for familiarity. Place the cursor on each icon to display the command name.
3. Click the open command to browse to the standard drawing from which the style will be copied. The selected file will show up in the list of style content
4. Right click the style of interest and select copy.
5. Right click the current drawing and select paste.

YOU CAN NOW LAYOUT YOUR FIXTURES, PANELS OR / DISTRIBUTION BOARDS AND CORRESPONDING LINKS
1. ARMED with your light design results from Hevacomp software or other related ones, select the electrical tab on the tool pallete and in the environment, select add devices.
2. Follow the guideline in the dialog box to select and layout the devices of choice on the archi base plan.
3. Using the same procedure layout the various equipment


Add panels and distribution board to the current drawing:
1. On the tool palette, under circuit and wire select add panel- a dialog box will emerge.
2. Fill in the content appropriately.
3. Set up the circuit manager and fill all the necessary content appropriately.
N.B. ENSURES THAT ALL NECESSARY CIRCUITS ARE ASSIGNED BEFORE ASSIGNING THEM TO DEVICES.
