How to export from 3D IPT to 2D DXF in Autodesk Inventor 2019

I really could not find a straight forward tutorial for exporting to DXF from Autodesk Inventor 2019, so I am making my own Note to self.

In Part view, right click object and select Create Drawing View.

Since we use sensible scales and values in Norway, pick ANSI (mm) as template.

Click the FRONT side, to get the correct view from the top. Then click OK, it doesn’t matter where the object is located.

Go to Save As, then Save Copy As.

Pick a filename and click Options.

Enable Customize DWG/DXF, and pick the FlatPattern.xml, click Next.

Change data scaling to Full Scale (1:1) and Closest to AutoCAD Mapping. Click Done and Save the file.

Find your saved DXF file, and check it in a different DXF viewer, like Autodesk DWG Trueview 2019.

Below we can see the 2D result of your 3D project. Use the Measure to check some points if it correctly in scale.

This model is 1555 mm in length, and thats exactly what I measure. 1:1 spot on!


Norwegian TwoClock Clone v.1

I loved the TwoClock since the first time i saw it. But the prices were insain. And I thought, how difficult could it be to make it myself?

I had a couple of 8×8 RGB matrices laying around, and with help of the great Adafruit tuturials ( figured out how to address the RGB pixels.

Started the deveoping of code with the Arduion Mega 1280, for easy access to IO. When I was done, I moved on to use Arduino Pro Mini ATmega328P clones from China.

The norwegian telling of time is a bit different from english. instead of “half past one”, we say “half two”. And “twenty past two” becomes “ten to half three”. So my code is pretty much useless for the rest of the world, unless you redo the logics.

Code is here:
