3 Layout, Measurement and Drawing Layout Tools inside and outside calipers dividers scribes rulers squares leveling tools

4 Layout, Measurement and Drawing Layout Tools marking, using a divider

5 Layout, Measurement and Drawing Layout Tools marking, using a... Sharpie or a scribe Mechanical pencils are also very good for this!

8 Layout, Measurement and Drawing Good drawings tell you a lot, excellent ones tell you everything: Basic info Looks Overall Size Material Part Name How many needed Details Tolerances Who drew it Context of the part Symmetries Repetitions Threads. Overall Dimensions, Scale, tolerances, Symmetries, Units, 3D views such as isometric or perspective-projection, find hidden features and cavities, features such as threads or surface finishes, tolerances. Try looking at it like someone who has never seen the thing that you are showing on your drawing. Enough info there?

9 Layout, Measurement and Drawing Drawings are a way to communicate what needs to be done can recommend an order in which to make parts should have everything relevant but not overload the reader naming: choose names that make sense to outsiders always include: scales, materials, features the context can be helpful to know go metric for dimensions (imperial only for not-upto-snuff audience, on demand. Lame!!)

10 Old way: Make Drawing. Use drawing to operate machines to make part. Or use it to tell machinists what you want. New way: Make 3D part using software. Feed into CNC machine that makes it.

11 First start of software: Set to millimeter, gram, second The default menu visible after opening a new part is Command Manager Get rid of that. Right-click top bar, un-check Then, check these menus: - sketch - features - tools - reference geometry - sheet metal See? Much better. No toggling between stupid tabs, you can reach functions with just a single click, and on top of that your wide screen is much better utilized as long as you move these menus to the sides. Recap: To pick your personal menus and set up your workspace, right-click on the empty useless space in your windows-window (E.U.W.W.S.) up on top of the screen that every windows user is endowed with regardless whether they want it or not.

12 And to make it even better: Define you very own function keys! Recommendation: F2: shaded with edges F3: measure F4: others front F5: others right F6: others top F7: others isometric F8: insert mate F9: wireframe F10: normal to F11: modify persepctive F12: view perspective Once you get familiar with SolidWorks, you can set your own preferences.

13 Setting up your workspace - there are way more buttons than you think! - drag and drop to make your very personal menus. - to activate SW Simulation: tools add-ins - check start-up button if you wish it to start automatically (but that eats resources) SW needs lots of resources. Free some on your computer by going to system. advanced.. performance.. adjust for best performance Run msconfig and do a selective startup, getting rid of lots of junk your machine might be running in the background. (keep your virus scanner) Restart often. Windows likes that.

14 Making Parts: - blue lines: bad - black lines: good (defined vs. under defined) - use relations and auxiliary lines to define lines and drawing features When making more parts by using save as copy, beware: - the original part in your assembly will be replaced by that newly saved part - there is a button in the save-as window that you have you check to make that won t happen unintentionally.

15 Solids: Extrusions are not all the same Sheet metal can be bend, the other can t Boss-Extrudes can have lots of copied and patterned features, sheet metal parts will give you error messages When exporting DXF files: - Name DXF files that are destined for waterjet or laser cutting as follows: 3x LEG steel 0_7mm thick = telling it all! - always know the overall dimensions of your part, that helps when you work at the machine. Knowing is better than guessing!

16 Different file formats are needed for different machines: Waterjet and Laser: 3D Printer: DXF STL Repeat: Always memorize the overall dimensions of your part! When opening your parts at a machine, you will be able to see if your part is still the right size, or if if got scaled up or down by accident. Happens frequently!

17 Other good systems to keep track of what you are doing are folders named for years, months, and dates of when things were made. Companies will freeze designs at certain times to make sure earlier products can be reliably repaired and maintained.

18 Assemblies - always assemble things the same way you would in reality. - align bolts concentrically to holes, giving rotational freedom - use advanced alignments and mates to define limits of motion, angular limits, gear ratios and more. - see the tree to the left for information about parts being fully fixed or not - tree can be partially undone by dragging the below line upwards Don t put assemblies together and leave parts hang in mid-air. You might think everything fits and works just fine, but in fact it does not.

19 Simulation.. We really hope you free d up some system resources earlier.
