So, at the risk of opening a can of nematodes on Simon's thread, what CAD systems would folk recommend? But please, not one that's going to cost two grand a year!

I use the free version of NanoCAD - a clone of AutoCAD 2D.

nanoCAD Free - Free 2D/3D CAD Software

nanoCAD Free is CAD application that delivers a great user experience by providing high performance, full capability, a classic interface and native DWG format support.
nanocad.com nanocad.com

When the upgrade prices of AutoCAD LT became almost stratospheric, I moved to Draftsight, an LT clone which was free. But it also changed to a $299/year subscription a year or two ago, and I then found the free version of NanoCAD to use instead. It's not the latest all singing-dancing version, but it retains all the features that I require for my model railway drawing needs.

There are some tutorials around on YouTube - here's one :-


The free version is their Version 5 (the current version is 11 :) ) so searching for Version 5 tutorials could get you more.

Jim.

I'm very happy to have the discussion here, but thinking of the future accessibility for folks that are looking for a given subject, I wonder if better to move it to a specific thread, as we have for resin 3DP.

Apologies...

CAD for laser Cutting etc..?

Picking up from the topic started on SimonD's workshop thread... Can anyone suggest a CAD system that could be used for producing files for laser cutting and more general model railway use? But hopefully not one that costs around two-grand per year! Many thanks... Dave C

My main niggling worry with Lightburn is that I had picked up on digging through Internet that placing kerf offsets might not be straightforward and that Lightburn tends to place them as it saw fit, which is not what I wanted. Also you couldn't see beforehand on which side of a line the offset was. With Cut2D I can place a kerf offset for any part of a drawing and can also see and check where the cut is placed before I send the file to the laser cutter. I'll maybe now do some checking with Lightburn to see how their offset placing works. :)

Kerf offset is easy to tweak (although 3 decimal places might be overkill):—

Positive kerf is outside the shape & negative inside. Measuring the kerf with a set of feeler gauges will give a start point

The other smaller consideration is that Cut2D imports DWG files whereas Lightburn only imports DXF files, and when it imports these files, it places them in the centre of the working area and not with reference to the original placement in the CAD file. I do all my 2D designing in AutoCAD 2D or one of its clones, so direct import of DWG files is a plus point.

I use Illustrator CS6, & Lightburn will import the outlines directly. It ignores any live fonts & effects though. Current importable formats:—

I'll probably dig around a bit more with Lightburn to see how it performs and have a look in more detail on how it deals with kerf offsets. I do like some of its features, like the Material Test application which is really handy for assessing cuts or etches for new materials.

So I've got both pieces of software on the HP laptop which works with the laser cutter and both will probably get used. :)

I tried it on spec & after about a week of using it happily dropped £50 on it to get a full licence. I found it to be very intuitive, although I wouldn't use its drawing tools for anything complex - quite happy with Illustrator for that.

Lightburn are set to introduce a new program called MillMage that'll cater to grbl-driven Spindles. If it's as straightforward as LB, I'll have that too. I'm currently using EstlCam, which is OK, but I'm not enamoured by it - I find it a bit crashy.

My experience is similar, I do all my drawing in QCAD and then import it into Lightburn. Although I do use Lightburn for adding any text as the tools allow adjustment of spacing and path following.

Thanks Phil

Hope it’ll get more opportunity to stretch its legs soon

Meanwhile more baby steps

There will be points but no prizes for the first to spot what’s been added. :)

Hello, Simon. Is this one of the rebuilt Manning Wardles that ran on the Cleobury, Mortimer & Ditton Priors Light Railway?

Dave,

no, it’s a 1366 - Collet pannier version of Churchward 1361 saddle tank, which itself was a derivation of the 1392 Class, originally built in 1874 for the Cornwall Minerals Railway.

It’s @Pencarrow ’s loco for his Bodmin-look-alike project, Agenoria kit with my chassis & 3DP. Slaters wheels, ABC motor/gearbox, decoder not yet purchased. Warren Shepherd castings to be fitted, along with steps, brakes, handrails, etc.

I think this might make someone smile


17 on the hook, 1 in 100 but steeper in parts, on a curve, and it’ll start them easily (perhaps more due to the ABC gearbox than any magic from my workbench!). Happy on the pointwork, seems very sure-footed due I think to the CSB.

That's a cracking achievement Simon, and to think it nearly ended up in the bin.

I think walking away with 17 on means it will somewhat adequate for Pencarrow's clay trips. Great stuff.
