What software are you using Adam ?

Hi Adam, I introduced myself to CAD just months ago, not even a year ago. I went straight to 3D CAD and I have never used a 2D CAD software. I am on Solid Edge because that's what a friend used and that's the only one I ever used. How does that compare with Solid Works ?

Joan, I am similar I went straight into 3D from doing it briefly at school and then not doing any till about 18-20 months ago where I then just got stuck in trying things, first thing I ever tried doing was a 2 1/2" gauge Toby chassis which was a great learning experience as the Toby was designed to be a simple build with whatever you have in the workshop so modelling it all was quite simple but taught me the basics well. I tried using Solid Edge when I worked on my placement last year and I really struggled, the user interface seems so much different to me and almost backwards after being so used to using solidworks - I imaging after having a course in it (I am starting back at the company in August full time so hopefully will be sent on one) then I would get the hang of it pretty quickly. One thing I found has really helped with my modelling is having a 3D mouse. It allows me to basically hold the model in my hand (sadly not literally) and move it in any way I want and look at it in many angles instead of trying to use the mouse whilst performing tasks. Adam

At the prices quoted of $4,000 solidworks or $5,300 solid edge you have to be a very serious user.

Hi Adam, I think one distinct feature of Solid Edge is the so called synchronous technology, but it came to me as a natural thing and I didn't think that it wasn't available in other softwares. In fact I do not quite know how to use the 'ordered' environment, which is the way to model things in Solid Works I think.
About the 3D mouse. I am 50 y.o. and suffer from carpian tunnel disease. So I must avoid pressing and rolling the mouse wheel at the same time. Instead, I set up a key in the keyboard which I keep down with my left hand while moving the mouse with my right hand without exercising any force on it. This helps to alleviate the pain in my wrist at the end of the day. But that's of course another story.

Hi Bryan, well I was not meant to compare the price. Of course I know how to use google, butI I just meant to ask why a particular person chose a software, which was answered. :-)

That's fair enough Joan, all of my friends (who don't do CAD) find the 3D mouse so fun and a pain to get the hang of, I am right handed but because I sit at the desk using the mouse I have picked up using the 3D mouse with my left hand - can't really do it with my right its very odd! I haven't tried to the synchronous side of solidworks as like I said i struggled to get used to it so didn't end up doing to much design work whilst working there, anything I did to I did at home and took in.
I think Brian was just stating a very obvious point that comes with using these types of software.

Hi Adam. I see Brian's point and he is right about the high prices of them. I was lucky because I am using a spare licence a friend of mine is not using at this time.

Evening, So progress on this project has been rather slow as of late with a multitude of things getting in the way but I have decided to have a bit of a drive on it for this week so have a brake from other things (although I'm about to do a new update on my fittings thread too). So not a huge amount has changed from last time but i have modeled up a complex part in the form of the motion brackets which is my starting point to getting the motion together and start working out a few calculations too see if I am on the right line. Here are two views of the RHS bracket showing how complex it is, the drawing was quite hard to get my head round to start with but I got there in the end. Here is the RHS on the chassis A close up render showing the top slide bar in place And I decided to throw a smokebox barrel in just to show the chimney I did ages ago. Lastly a look at the size difference between a 5" cylinder block and a 7 1/4" Thanks for looking, Adam

lovely work Adam....top work sir.... Pete It's amazing how things like a smokebox and motion brackets totally changes the appearance of it. It goes from not a lot to something wuite different Adam

Hi Adam,
brilliant work, continued to be amazed. Does your software provide data on the weight of the cylinder casting? I assume that it will lighter than a standard casting, which would tend to be more solid than the one you have modelled.

Brian,
I haven't seen any feature that provides that data yet.
If you were to look at cylinders individually then I image it would be lighter than a casting you typically buy these days as it isn't a solid block with two holes in it but as a single unit I image its going to be quite a lump - undecided yet if I will go for cast iron or the Silicon Bronze we have been using previously.

There is a feature in Solidworks that will give you the weight if you tell it the material, Paul used it to give me a weight on the cylinder blocks we were going to cast for mine. I couldn't tell you how to get to it, I'm not that good with Solidworks yet, but it is there.

What do they always say? One step forward two back! Damn!
I started to assemble the cylinders, frames, slide bars and motion bracket and quickly found that there was an error with the mounting of the slide bar as the mounting holes didn't line up. After some investigation it became pretty obvious the issue was to do with the cylinders (S***!) so as much as I don't want to I have decided to start the model again and take on what I have learnt in the 12 months since I last did it and have another go at it. I am going to redo the mounting holes in the main frames also to ensure I have all of those right but from fist inspection most are correct.
The first model took me around 100 hours roughly, lets hope this one is a bit quicker!

Hi Adam, that's a pity. On the positive side, your redrawing of it will surely result in a better model. This always is the case when you do creative work
