I had a ChatGPT experience

I am currently working on a timing synchroniser for the local church clock. Being of that generation I had come up with a CMOS based phase detector with monostable timers etc. This logic looks at the relative timing of the clock strike activation and a DCF timecode reference clock. I prototyped the circuitry, proved it and made a PCB for it in Fusion. It works very well and the resulting output slows or speeds up the clock by adding or removing lead shot to the weight tray on the clock pendulum.

I got my ear bent for being so old school and not using an Arduino or similar but I was reluctant to stray from known and proven simple logic with RC time constants. In the end I caved in and out of curiosity thought it might be a good project to get my feet wet with ChatGPT.

It took a little while to find my way round the ChatGPT site and to get to the software support section. Once there I entered in simple language what I was trying to achieve. ‘It’ replied with its understanding of my needs and I agreed this was correct. I then asked for some code for an Arduino UNO.

Out popped 44 lines of Arduino code …. which worked. Oh my goodness, what a revelation. Think I need to have a cup of tea and biscuit to recover. Like Fusion and 3D printing, this is going to completely change my workflow and project practices.

Fusion Sheet Metal model export as PDF

The Sheet Metal module in Fusion allows you to create a 3D model of a folded sheet metal part and then ‘flatten’ the model to provide a net shape with fold lines. It is quite easy to use and impressive in the results you can achieve. The model can be adjusted for different metal types and their properties. The resulting flat net can then be exported as a DXF to send off to a laser or water cutting sub contractor.

The Fusion Sheet Metal module only allows the flat net data to be exported as a DXF file. This is not surprising as this is the most common data file request from sub contractors. That having been said I recently had a request for a PDF file which at first glance is not an export option in the Sheet Metal module. One solution was to use a web based DXF to PDF converter but this could be potentially unreliable in the conversion result.

A less obvious solution is once you have created the unfolded (flat) net, open the Drawing module in Fusion and use the From Design option.

This will load the unfolded net into a Fusion Drawing with the ability to be exported in PDF format. This is quite a useful export route to take as you can dimension and annotate the drawing in more detail than would be possible in the standard DXF format export from the Sheet Metal module.

The use of this Drawing module export route is going to be fairly rare but it is a useful option to know about and have up your sleeve.
