Draftsight

Situation:

Having now learned about sketching, orthographic and isometric drawings, it is easy for you to communicate effectively with pencil and paper throughout the technology design process. With the advancement of computers and software applications, it has helped people today get things done faster, more efficient, an

d more organized. It has also saved on the environment in many ways including paper saving. Drawing programs have come a long way in the last 15 years and it is a great way to not only communicate, but also modify and update your ideas very easily.

Problem/Challenge:

Using the recent orthographic sketch of the step block, redraw using absolute coordinate system to draw the three views and use a new layer to draw the hidden lines in the appropriate views. Spacing is to be 40 mm between objects and at the using the text tool write in your project information prior to handing in, in the form of the program's proprietary file format dwg and export also as a PDF.

- TOP - Draftsight Introduction

DraftSight is a free 2D drawing program that can accurately draw objects using simple commands- video video Introduction, 3.06. This type of program is commonly used in a variety of fields where layout drawing plans are needed to communicate a lot of information graphically. Drawings use the Cartesian coordinate system and there are two major ways to enter lines, either absolute or relative coordinates. Simply put absolute coordinate system uses point entry method based on a single starting point or origin, where the relative point entry method you enter coordinates based on your last coordinate location. More details on command entry which also talks about the type of coordinate system you can enter in such as Cartesian (2D / 3D), polar (2D), cylindrical (3D), spherical (3D) with Cartesian and polar most often used. Before starting to draw your step block, explore the program, experiment with different tools and familiarize yourself with the applications interface, as it is similar to other CAD programs used in industry. The DraftSight Resource Centre has lots of support files you can view including videos showing the basic steps.

- TOP - DraftSight Support links

You can download a in-depth guide to PDF Getting Started if you want more information on the operation, tools, and interface. Most recent introduction video tutorials video Draft sight Les 1, video Les 2 , and video Les3 can show you the basics, video play list of specific tools, video play list of lessons, and/or view a longer version of video DraftSight Fundamentals webinar showing the program in more detail. DraftSight is free to download and use at home to not only work on related school work but also for your own projects. Remember while working, save your work to your USB flash drive and always backup to your H drive at school or if you are working at home backup to your home computer.

- TOP - DraftSight Tips/Tricks and Key Information
tips
  1. General settings go to Tools, and select Options to access all the general settings for the program
  2. Background colour using Options, System Options, Display, select Model background, then change colour to white, although the default black will work fine
  3. General set-up Limits CMD (Command) sets your model workspace area, Units to change decimal place holder and units, & grid spacing
  4. Z for zoom, then letter for type of zoom such as E for extents, A for all objects, etc.
  5. Absolute coordinates allows you to enter location based on the origin point in relation to where you want to draw or locate a element
  6. Relative coordinate entry allows you to enter a location based on last location
  7. When drawing lines, having Ortho Snap on, you can save some time drawing lines that are straight horizontal or vertical by using the cursor to show direction, then just enter in the distance and press enter to draw that line
  8. "From" CMD will allow you to offset your starting point location of a line or object
  9. E-snap allows you to quickly lock onto common feature points of lines or shapes
  10. E-track will allow you to align a edge or e-snap point to another view or drawing location
  11. Use Layer Manager to create new layers to manage different parts of your drawing like object, text, dimensions, notes, special views, etc and control colour, view, line thickness, line type, layer, scale, locking etc.
  12. Layer or selection changes you may need to scale dimension lines, arrows, text, special lines, etc, doing so with a selected component will only change what is selected, or with no selection will change everything on that layer
  13. Using Note Tool will allow you to make notations
  14. Using Dimension Commands It is recommended to enter dimensions on a newly created layer, thus giving you more control on your drawing
  15. Adding new specialized lines, you may need to load them from the library to insert into layers
  16. Line weights in model space not showing up may be addressed by using the lwdisplay command and setting to 1 or going to (in classic view) Format> Line weight> check on Line weights in graphics area, you may also need to make sure they are also checked on in the options, drafting styles, active drafting styles, line weight by layer, display weight in graphics area
  17. Linetypes not displaying properly in sheet view, enter the command ENBLVPLSCL and set default from 1 to 0, then enter the command Regen to regenerate the view
- TOP - DraftSight ISO Drawing View
  1. Adjust cursor - Options >System Options >Graphic Area, select cross hair with pointer size increased %100
  2. Create ISO Grid - right click on Grid button, Settings, Grid settings - select isometric
  3. Three separate planes; left, top, and right - toggle through using F5 key and the command window will tell you which one you are on, or just view the cross hair directions
  4. Put ortho on by clicking on the bottom icon with the ortho symbol button
  5. Using line tool create your ISO on a new layer, start a line off the right side of regular limits at full 1:1 scale by moving the mouse in the direction you want, then just enter the unit distance
  6. Use ellipse tool to access isocircle option to draw circular holes on ISO planes, you may need to use temporary construction lines to find centres
  7. Once finished your ISO, make a copy of your ISO, then use the Scale command (with appropriate scale ratio) to reduce your copy to fit appropriately in the third quadrant, and hide/freeze your original off to the side

TipWith the current version of Draftsight in step 7 above, you need to type in the ellipse commas in the command prompt (clicking icon in tool ribbon will not work), to be able to use the i (ISOcircle) tool option to create the proper ISO circle. Remember to create it on the correct plane.

- TOP - Creating Step Block in Draftsight

Using the 2D CAD program called DraftSight, create an ortho of the step block as in our final sketch in the past unit, using the following brief steps used from the live demonstration from the instructor.:

2D Step Block sample

Views, Text, and Lines

2D Step Block sample

Dimensions & ISO


  1. Go to your school pick-up folder and save the blank template file to your critical file saving location (USB with a new folder titled 2D CAD) which has a completed paper space info block done for you with some global settings updated for you
  2. Create new file, select the template file you acquired
  3. If this is the first time using Draftsight you may want to change options to your liking (hint review Draftsight Les 1 & Les 2 video tutorials
  4. Type in Units, change decimal to 1 place holder, change block units to mm
  5. Turn grid on with grid button at the bottom
  6. Type in Limits, then enter for default "0,0" and then "150,120"
  7. Type in Grid, and then type 10 to change the grid density
  8. Type "z" for zoom, then "e" for extents, to show the whole workspace
  9. Use the polyline tool and enter Absolute coordinates "10,10" (x,y) as your starting point and continue with the rest of the object line points to finish view
  10. Calculate 2nd view Absolute coordinate to start polyline, then try Relative polar coordinate entry by entering @ symbol, the length of travel then the < bracket with the angle you want to travel usually 0, 90, 180, 270 degrees, ex @30<0
  11. Continue to enter the rest of the coordinates to finish the ortho step block's 3 views, experimenting with different entry methods
  12. Use the "From" command to locate your circle hole feature
  13. Using the layer commands, make a new layers for hidden, centre lines, dimensions, ISO original, and ISO scaled, with object and hidden line weights of 0.50, dimension and centre lines at 0.25 weight
  14. You will need load new line types and/or also set scales of each, depending on your global settings as you want the entire layer to default to your Bylayer
  15. For isometric, set cursor and iso grid, turn ortho snap on and draw your isometric outside your drawing limits on a new layer, so that you can copy to a new layer and scale to fit in your drawing envelope area, then hide your original layer
  16. In sheet view (also known as paper space), you will have to reduce scale and adjust to fit in view port (double click in view port window to activate), then complete information block with name, date, material, and class
  17. Save in DWG and also export to PDF file format when handing in

TipEnsure the file extensions are correct and present. Here are examples of file naming conventions you should be using for CAD files:

  • DraftSight proprietary file format DWG: td2-1_d-joe_2d-step-block_60x30x30.dwg
  • PDF: td2-1_d-joe_2d-step-block_60x30x30.pdf

blocks

10 Block Challenges
Ortho-Practice

Now that you have a some awareness of Draftsight, it's tools, and operation, lets put that new knowledge, skills, and experience to the test using our previous block challenge. Select a different block than what you originally did for your sketch in Unit 2, and use the same steps you used to creat your step block, to create your new model drawing for that block. You are allowed to collaborate with a partner that has already done the block to discuss things such as the the correct front view of the object, features, dimensions, best ISO view, etc. to complete your new ortho/ISO block challenge with dimensions. Show all rough work such as calculations, sketches, ideas on the back of your PDF 2D CAD Ortho Self-Peer Checklist.

Considerations
Collaboration
  • Collaboration with partner to discuss which is the correct front view based on the three rules on selecting the front view
  • As this project is similar to the step block in terms of layers, you may use your step block file with the Save As command, and then delete your model object views, to re-use the layers
  • Drawing limits will need to be re-calculated based on size of your object, number of dimension ladders needed between views (40 mm will work with three ladders or levels like in the step block... it will depend on the amount of details your object new object has), and a 10 mm spacing around the views
  • Reviewing dimensioning standards and more collaboration with your partner will help with placement of dimensions
  • Remember to create your ISO view last, once you know how much space you have, by first creating it at full scale and then reduce to an appropriate scale that will fit in the third quadrant of your model space drawing

- TOP - Google SketchUp Introduction

Google Sketchup is a free program and has a lot of support on the Internet including forums, part database, and tutorials. This program is closely used with Google Earth to build and show 3D buildings on it's maps. This program application has many setup configurations to allow different types of drawings and standards. The drawing tools represent simple tools and icons for drawing and push/pull shapes into 3D. This program can be used to draw simple or complex objects very easily. Review your dimension rules and standards and how to keep them to a minimum but also ensure you have enough to re-create it if needed.

- TOP - Creating the Step Block using Google SketchUp

Here is a list of the major steps that were show during the class demonstration, and a final 3D drawing sample that you can follow if you need extra support:



2D Step Block sample

Sample 3D Step Block

  1. Select template: Product Design and Woodworking – Millimeters
  2. Draw a rectangle using the Rectangle tool, type the exact height, press enter
  3. Use the zoom extents icon to re-size, re-draw and center your object at any time
  4. Use the push/pull tool to pull up the object up, type the exact height, press enter
  5. Finish the rest of the block using the same tools/process
  6. Tip: use the tape measure to create infinite/construction lines to locate centre for hole
  7. Use the colour tool to create a transparent colour
  8. When finished drawing your 3D object, rotate/align the view so that it shows the most features, maximize the landscape space, and allow for adding appropriate dimensions
  9. Create/show dimensions by selecting the Annotation tab and select the appropriate dimension tools
  10. Show overall and detail dimensions outside of the ISO block envelope following similar techniques and rules with an ortho sketch
  11. Save in proper file format in two file types: SKP and JPG formats
  12. Use File > Export > 2D Graphics for creating the JPG (ensure image/dimensions are taking up most of the page
  13. Tip: ensure view is centred and full screen prior to exporting to JPG

When you are finished check with two peers to ensure you have completed the tutorial correctly. When handing in any files, you will submit the in the Drop-Off folder as discussed in class, in the proprietary program file format extension SKP and also export to a JPG format. Ensure the file extension is correct and present. Here are some examples of file name you should be using:

  • SKP - Google Sketchup file name example: td2-1_d-joe_2d-step-block_60x30x30.skp
  • JPG - Joint Photographic Experts Group file name example: td2-1_d-joe_2d-step-block_60x30x30.jpg

For your final challenge, you are to use your custom ortho block as a focus and draw it using the dimensions you already have from your sketch previously done using the same process in drawing the step block above. Remember to put your dimensions outside of the ISO box using the same techniques and rules of an ortho sketch. This time you will have to place them in the appropriate locations that makes them look neat, clean, and organized.

- TOP - 1. Overview and Sketching Projects

This section introduces you to 3D modeling, OnShapes' interface, design intent, sketching basics,dimensioning, and constraints. After you have reviewed the tutorial videos, you will be given two related drawing projects assignments to draw, follow methods, experience CAD tools, and learn some new techniques with sketches, dimensioning, and constraints. Ensure you have reviewed the related video's in the Investigation section above before starting drawing projects below.

Drawing Project Instructions

When you follow the PDF instruction sets, you will be given a link to a Onshape template which you will need to log-on to site first. Set-up your Google Chrome Browser and opened PDF instructions for quick application switching such that you can ALT+TAB between them or if your PDF instructions opens with-in a TAB in your browser, then use the ALT+CTRL to toggle between each. You will need to make a copy of the template (create a new file based on original and name new file name).

Remember to save the file with the proper file naming convention: course code two letters and level, course section, project name, your last initial, first name, and description format. Example: td2-1_d-joe_2d-step-block_60x30x30

Version Save

After final save, also do a version save!

Once finished the assignment, you will need to create a final version "FV1" using the manage version button, use the description area to add supporting notes, then save version, and share it with your instructor (use e-mail address from the bottom of this page) so your instructor can view with full edit access for evaluation. Ensure you submit your submit your evaluation checklist sheet the same time in the hand-in bin, as not submitting it, you will lose marks and not get paper feedback on your finished project.


TipMake sure you have all your sketches Fully Defined prior to extruding, by making sure no blue lines are showing in your sketch (should be all black). Red represents over defined which means there are too many constraints or dimensions and you will have to remove some. Use dimensioning techniques and keep 2D sketch dimension layouts neat and organized. If you find that your part is not filling up with a light grey once you have closed all shapes, then you will need to check your line connections. Also ensure that your version FV1 of your part is showing the best isometric view, fitting on screen.


  1. PDF Basic Sketching - Link Bracket (Also in addition to instruction guide see below):
  1. Rename with proper file name convention, ex: td3-1_d-joe_ link-bracket_P_L-shape-4.5x1.75x0.12in
