8331 Madison Blvd, Suite 200B Madison, AL GEAR (4327) Introduction to 2D Design

Nomenclature LMB – Left Mouse Button RMB – Right Mouse Button MMB – Middle Mouse Button Will cover [menu bar] and hot-keys Program functions are italicized

Vector Graphics Defines points and lines with mathematical relationships Can be scaled up or down without loss of resolution Easier to edit Generally makes for a smaller file File types – SVG (Inkscape), AI (Illustrator), CDR (CorelDraw) Raster (or bitmap) Graphics Contains images that originally were not generated by computer (pictures, scans, etc.) JPEG, BMP, GIF, etc. More detail, edit pixel at a time Programs exist to convert from one form to another(inkscape is one) Vector vs Bitmap Graphics

Interface Menu Bar Command Bar Snap Bar Drawing Area Tool Box Color Palette Status Bar Tool Controls Change Width and Height

Interface Changing View Pan - MMB drag (or Shift+RMB) Zoom in - Ctrl+RMB Or use zoom buttons (selection, drawing, page) Or use zoom button and shift zoom button [View - Duplicate Window] can show details in new window! Changing page size Ctrl-Shift-D or [File-Document Property]

Basics Zoom Select Circles and Arcs Geometric Shapes and Stars Free Hand Bezier and Straight lines Text Space bar swaps between selection and last used tool

Managing Objects Your best friends! [Edit – Undo] and [Edit – Redo] or Ctrl-Z and Ctrl-Y [Edit – Cut] [Edit – Copy] [Edit – Paste]or Ctrl- X, Ctrl-C and Ctrl-V Scaling –single click and move the arrows on corners Rotate – Double click the object and select curved arrows (holding ctrl locks at 15 o increments) Cloning – [Edit – Clone – Create Clone] or Alt-D [Object – Fill and Stroke] or Shift-Ctrl-F [Object-Group]-Ctrl+G

Advanced Methods Locking Objects – Ctrl-Shift-O or [Object Properties]. Can only unlock by editing XML file or by [Object – Unlock All]! Hiding Objects – Use [Object Properties] dialog. Unhide using [Object – Unhide All]! Tweak – Nudges vectors based on how far they are from the mouse cursor Edit Nodes – Great for adjusting curves, precise movements

Advanced Methods Vector Math Clip – [Object – Clip – Set] trims objects to geometry of vector object Mask – [Object – Clip – Set] both clips and sets transparency based on vector object Paths – under [Path] [Union] [Difference] [Intersection] [Exclusion] Etc. Pictures next to the tool tells what the tool does

Tips and Tricks Use notches and small clearances to allow pieces to interface For Laser Cutter Engraving pictures use low resolution Engrave first, cut later For CNC Make sure vectors are closed Pocket first then cut Don’t be afraid to screw something up. Screw up something cheap before making a final cut

Laser Cutter Can etch woods, metals(anodized or laser marked), and some plastics(no pvc) Can cut wood, plastics, and rubber Save the file out as an.svg (for future edititng) and as a.PDF (to use on the laser)

Laser Cutter Rastering Rastering=Etching or Engraving The image might have to be tweaked in inkscape to produce a clear etch DPI = dots per inch that the laser pulses Stamp – inverts grayscales Includes a shoulder Mainly for engraving rubber Vector Vector means cutting In order to cut the line must have a thickness of 0.001in or 0.090px Tabbed Box Maker Simple plugin for Inkscape Use setting for kerf

CNC Vinyl Cutter CNC Can cut woods and soft metals Save the file out as an.svg (for future edititng) and as a.eps or.dxf (to use on CNC).eps works the best Line width does not matter Make sure vectors are as closed as possible Vinyl Cutter Only cuts an outline of an object Make sure lines are joined Copy and paste inkscape work into Roland cutting program

Lets Make Something Fun I’m going to make a make I MADE THIS AT MINDGEAR Plaque The plaque you make does not have to be the same but need to fit 3x5in Lets begin by drawing a 3x5in box and rounding the corners

Lets Make Something Fun Now I’m going to put some text onto the plaque I’m going to rotate the text to give it some flare

Lets Make Something Fun Instead of just typing MindGear I am going to import a picture from the internet You can do this two ways [file-import] or copy and paste

Lets Make Something Fun Before we save this file to make our plaque we need to make sure everything we want to cut has a line thickness of 0.001in and everything we want to etch has no stroke and is filled
