In order to scale the boxes I make, I decided to go through the (somewhat painful) growth from 2D to 3D drawing.
I'd been importing Boxmaker pdf files to CorelDraw 5 and tweaking the files a bit to make the files ready for laser cutting.
I want to modify a few basic parameters to enable changing materials, while using the same part drawing.
I took some time at TechShop in San Jose to learn how to get my files from Autodesk Inventor 2013 to CorelDraw 5.
I saw this Instructable, but did not get the same results. It appears there are some changes between saving from Inventor 2013 to CorelDraw 6 instead of CorelDraw 5.
Step 1: Export the Sketch
While in 2D Sketch Mode in Inventor 2013, go to the Browser and right-click the sketch icon.
This generates a pop-up menu, allowing you to export the sketch.
Select the Export Sketch As option
Step 2: Choose how to export the Sketch
Export the Sketch in a .dxf format.
I had inconsistent results going from Inventor 2013 to CorelDraw 5 when I selected .dwg, so I'm sticking with .dxf.
Step 3: Import the .dxf file to CorelDraw 5
Now you're able to import the dxf file to CorelDraw 5, while retaining your original sketch measurements.
Step 4: Confirm the dimensions
I used CorelDraw 5's Segment Dimension Tool to add dimensions to the imported vectors. They are consistent with my original Sketch.
Step 5: And add graphics and send to the laser
Now I'm able to change all lines to vectors (hairlines in CorelDraw), add any raster graphics, and print to the laser engraver.
