What I?m doing is using fusion360 for curved practice parts. The spline tool seems to work seemlesssly there

And staying with solidworks for parts with straight edges

I was kinda hoping to not have to learn 2 systems but I guess it is what it is

I?m a little disappointed with solidworks about this... looking at the forums people have been talking about this since 2011... I don?t know the behind the scenes math of why it won?t work but you would think they would have worked out something by now.

Default If you didn't know...

Heads-up: Solidworks gives a free license to EAA members. It's a killer deal. Several thousand bucks worth of high-end software.

Default Printing accurate cutting templates

share some info I’ve learned doing some research

Many printers are not accurate(when I say accurate I mean long or short up to an 1/8 of an inch over a yard). and anything you print should be double checked. You might have to scale it up or down a little . But even then you should check that it got scaled evenly on both the x and y axis

Some printers are accurate on the x axis but not the y

I don’t own shares in the company but after trying a few different printing shops and a few printers in each shop

The Hewlett-Packard page wide printer seems to be very accurate ... over a yard/meter test print I could find no diviation.. it was spot on... but I still do a quick test measure up and down the page to check it.

If anyone is familiar with other good printers or what to ask for as far as a calibrated cad printers... please educate us. Maybe these print shops need to calibrate their printers?

With that said I would double check your testing ruler against another ruler or caliper to make sure that’s accurate..


With a good printer you can make templates to stick on your aluminum. that once cut out should match your project demesions

If I were going to all the trouble of drawing up the part in CADCIM, I'd use CNC technology to 'print' the part. I haven't used Solidworks for sheet metal, but other parts have been done for me on a CNC mill, for example. I'm sure you could find a shop that will cut sheet metal to your drawings. If you are templating the bend lines, the usual practice is to use forming blocks with tooling holes to fix the blank on the block. Too bad SW does not have a feature to autogenerate forming blocks based on the drawing and material.

Yes, and uh there is a reason for that....I have been using the EAA version for several years. They got me where they want me . If I ever needed a commercial version of CAD it would be Solid works due to the amount of time I have spent learning it. Even if another vendor was super cheap.... I hope they never discontinue the education version with EAA or I will be out a luck.

Um... No. PDF was designed specifically to contain vectors. But it may also contain bitmaps. What Solidworks exports in PDF's is not bitmaps, it's vectors, but curves are made up of short (vector) line segments.

If you're designing parts for machining/forming/etc. later, and people will be making the parts from a Solidworks native tile, or a STEP or IGES output of that Solidworks file, there's no reason to use Fusion.

If you're planning on making a PDF and printing it out and having a shop make a part from that PDF, then you're already accepting a quality level that isn't going to be affected by having the curves show as short line segments...
