BLDC 2400 – Architectural CAD 1
WEEK # 6 – Term Project
H:\BCIT\Bldc 2400\Week 6\BLDC 2400 Term_Project_200930.Doc Page 1 of 6
Objective: The objective of this assignment is to generate a basic set of architectural design/working drawings, all within one AutoCAD drawing file. Upon completion, the file should consist of plans, building elevations and a building section – all set up on three title sheets complete with notes, symbols and dimensions. This project will allow you to incorporate all the AutoCAD skills you’ve learned to date, as well as more skills to come. Drawing accuracy, proper layer management and avoiding those dreaded “bad habits” will result in a clean, well coordinated set of architectural drawings – ready for printing once it’s complete. Due Date: See page 4 for the due date, submission requirements and a checklist of project expectations.
File Name: lastname‐termproject.dwg
Drawing Setup: It is recommended to start this project by creating a new AutoCAD drawing based on your current architectural template file as created in class. This will ensure the drawing Units, Layers and title sheet will already exist, eliminating the need to re‐create them from scratch.
Title Sheet: The assignment is to be drawn in Model Space onto 22” x 34” title sheets in landscape format. Even though this title sheet has already been created in your template file, it will require scaling up to match the final drawing/plot scale of this project (see Scale Factor below). How to do this will be demonstrated in class, most likely during week 8. Complete the text information in all three the title blocks accordingly once AutoCAD’s text commands have been demonstrated in class. Remember to include ALL the important data in the title blocks, including scale, drawing number, drawing title, etc. Always reference the project requirements checklist at the end of this handout. Scale Factor: The final plotted drawing scale will be 1/4”=1’‐0”. Therefore, the Scale Factor of the drawing will be ____. This number is very important, as it will be used as a factor for many settings for this project. Its relevance will be demonstrated in class.
Drawing Units: Units should be set up as per your template file as follows…
Length Units: Architectural Length Precision: 0’‐0 1/32” Angle Type: Decimal Degrees Angle Precision: 0.00
Limits / Snap / Grid: Limits, Snap and Grid are NOT required and at this point are discouraged. In particular, you should NOT use a Snap setting for this project since it is virtually impossible to find a working Snap increment to suit the various dimensional increments of this project.
Layers: By using your architectural template file to start this project, all the Layers should already be there. Add/remove layers as necessary. Remember that organization is the key. Should you start this project without using your template file, create an architectural layer list as per the sample one provided for your template exercise. Double‐check the MEASUREMENT system variable and make sure it is set to zero before loading any linetypes. This will ensure that linetype scaling will work properly for the project.
LTSCALE / MSLTSCALE: LTSCALE (linetype scale) should be set to 0.5 and MSLTSCALE (Model Space linetype scale) should be set to 1. This will ensure that all non‐continuous linetypes will display correctly relative to the Annotation Scale (see below). For more detailed information refer to last page of the week 8 handout titled “Drawing Scale Factors and Annotative Objects”. Also refer to the basic drawing set up handout from week 3.
Annotation Scale: Set the appropriate annotation scale to ensure that all non‐continuous linetypes will display correctly. Setting the correct annotation scale will also ensure that all annotative objects such as text and dimensions will be placed in the drawing at the correct size relative to your “model”. The annotation scale for this project should match the drawing scale factor (see Scale Factor above). Remember; make sure the MEASUREMENT system variable is set to zero so standard architectural scales are available. This will be demonstrated in class but for more detailed information refer to the week 8 handout titled “Drawing Scale Factors and Annotative Objects”.

Drawings Provided: Note that not ALL drawings required for this project will be provided. It’s not uncommon to generate new drawings from existing drawings. For example, by copying an existing floor plan you can quickly create another floor plan by simply modifying the differences between the two plans. Quite often most of the information from one plan to the next is the same so it’s always more efficient to modify a copy of a plan, rather than starting a completely new plan from scratch. Having said this, here’s a list of required drawings for the project and whether or not they will be provided:
Ground Floor Plan: Provided
Second Floor Plan: Provided
Roof Plan: Not Provided (can be easily created from a copy of the second floor plan)
Building Section: Provided
Front Elevation: Provided
Side Elevation (your choice): Not Provided (can be easily created from copies of the building section and/or the front elevation)
All of the above plans, elevations and section should fit onto three separate title sheets. Suggestions on how to organize and layout the drawing will be demonstrated in class but it’s up to you to organize the information appropriately. Even though this is a CAD environment it’s still essential to organize all the information as you would in manual drafting to ensure everything is clearly legible.
General Drawing Approach: Like most AutoCAD projects, it’s recommended to complete the majority of the “model” drawings first. The “model” refers to all the objects representing items to be constructed. This would include the walls, windows, doors, millwork, roofs, etc. in plan, elevation and section. Remember, all these objects should always be drawn full scale, or 1:1. This approach is the same as what was done for the duplex floor plan assignment. Remember to use an efficient drawing approach by using the commands demonstrated in class. You shouldn’t have to re‐draw something that already exists in the drawing. Using various modify commands will allow you to quickly generate new objects from existing ones, saving both time and frustration. If this project seems overwhelming, it really shouldn’t be since there are many duplicate or repetitive items intentionally included in the project. If you practice the modify commands and use them efficiently, you should realize that completing the “model” drawings won’t be so overwhelming after all. Another important tip would be to frequently use the DIST (distance) command to check your work. This can catch some mistakes and hopefully eliminate/reduce those mistakes from spreading throughout the drawing. See the section below regarding the recommended sequence for creating the “model” drawings.
Then the annotation of the drawing can begin. This would include adding the notes, architectural symbols, dimensions, material legends, schedules etc. where applicable. Unlike manual drafting, all of these annotative objects need to be scaled accordingly to match the final plot scale of the drawing. Some of this will be done automatically for objects having annotative properties, but some of this scaling will have to be done manually by you. Refer to the upcoming section “Annotate the Drawing” on how to properly created annotative objects. As mentioned already several times in this handout, also refer to the week 8 handout titled “Drawing Scale Factors and Annotative Objects” for more detailed information on how this is achieved.
Drawing Sequence: After reading the above sections on “Drawings Provided” and “General Drawing Approach”, I’d recommend drawing all the “model” drawings in the following sequence. First the plans, then the building section, then finally the building elevations. Drawing accurate plans first will make drawing the section through the stair much easier. In turn, generating the elevations after the section is complete will also be easier. Commands like RAY and XLINE are used to create construction lines (similar to manual drafting) that can assist you with generating sections and elevations from the floor plans. Examples of these commands will be demonstrated in class.

Annotate the Drawing: Once the majority of the “model” is complete (see above sections), you can then begin to annotate the drawing as listed below. Annotative objects such as text (in the form of notes or schedules), architectural symbols (from your symbol library) and dimensions can be added. Remember, all these objects exist to communicate information about the model to the individual(s) reading the drawings. Since they are not “real” objects that are being constructed on site, they must be scaled accordingly to match the drawing scale factor. This will be demonstrated in class. Also refer to the week 8 handout titled “Drawing Scale Factors and Annotative Objects”.
Symbols: Almost all the architectural graphic symbols from your symbol library will be required for this assignment. How to copy and scale your symbol library into your term project drawing will be demonstrated in class. This is done by copying the entire symbol library from your symbol library drawing, and pasting it into your term project. If you’ve copied and pasted in a Windows environment before, this method is essentially the same thing. Please note that when copying and pasting objects from one drawing to the next, you must use the Windows method and NOT AutoCAD’s Copy command. AutoCAD’s Copy command is limited to copying objects within the same drawing. How to place the individual symbols in your drawing will also be demonstrated and discussed in class but it’s essentially the same as to how you would place them in manual drafting. Number the doors and windows using a logical approach/sequence of your choice. Where applicable, add elevation references, spot elevations, section references, drawing title identifications and a north arrow to your drawing. Grids will also be required and should appear accordingly in plan, elevation and section. You may also use the provided plans/elevation/section as a guide for the placement of symbols. Text: Separate text styles should exist for notes, dimensions and titles. Refer to the template exercise on which text styles should reside in your drawing. You can re‐create the text styles required in your template file or simply copy and paste them into your term project. How to copy text styles from one drawing to another will be demonstrated in class (see sub‐ section on “Symbols” above regarding copying and pasting objects from one drawing to another). You may add extra text styles as needed. Note that all the aforementioned text styles are in addition to the text styles created for your symbol library assignment. Remember to always use a font name that is easily legible. Add text to your drawing similar to the notes provided on the plans/elevation/section drawings for this project. Remember to complete the title block text for all the title sheets as well. You will also be required to generate an exterior elevation Material Legend using text. This list will vary from student to student since it will be up to you to select the exterior finishes of your choice (cladding and roofing). See the section below on Hatching. Finally, you should add text to the following rooms in plan to indicate the room sizes. The room sizes aren’t provided so this is a great example of where the DIST (distance) command can be used to quickly obtain room dimensions. Where you choose to take the length and width dimensions for the rooms is up to you. Provide room sizes for…
Kitchen, Dining, Living, Bedroom and Master Bedroom
Dimensions: Only one annotative dimension style is required and how to set this up will be demonstrated in detail during class. Refer to the week 9 handout on dimensioning. Dimension the drawing as you would in manual drafting. You may use the dimensions provided in the handouts as a guide. Layout dimensions in a clear, organized fashion, avoiding clutter. Dimensions shouldn’t cross over notes and the dimension text should always be legible. Don’t feel you have to dimension everything. More is not necessarily better. Dimensioning in AutoCAD can be a very quick and easy process but it’s still critical to place all the dimensions wisely.
Hatching: Provide appropriate hatch patterns to the building elevations. The patterns you choose is up to you since you must decide on the materials for the exterior wall finishes (cladding) and roof finish. Select an appropriate scale for your patterns and note that this may take some trial and error. Some suggestions for exterior claddings may be stucco, brick veneer, lap siding (wood, vinyl, etc.) or perhaps wood shingles (cedar). For roofs, it will be limited to shingles of some sort (cedar, asphalt, etc.) or metal roofing, but finding a hatch pattern for metal roofing might be challenging. All the finishes you choose should be labeled and correctly referenced to your exterior elevation Material Legend.
Floor Area: Provide text noting the floor area in square feet (rounded down to the nearest square foot) for each level for each unit. Since this is a duplex, I’m not interested in the overall combined floor area for both units. Obtain the floor area from polylines drawn around the exterior of the unit to the centre of the shared party wall between the units. Place the text noting the floor area below each plan where it can be easily identified.
