    Quite usefull and it is for free. I got this on reccomendation when I did a structural detailing course.

    Like most 2D/3D cad programs.
    They either work for you or they don't.

    Find a free course on Youtube. Start and stick with it till you are proficient.

    I use AutoDesk Fusion 360. I was battling then bit the bullet and worked my way thru about 30 sessions.

    There is a whole new world out there once you can model in 3D, the worlds your oyster.

    May I suggest that you make your drawings more friendly for the bending brake operators - flip the part over so that most bends are up.That is the way that their minds work.

    Mike, I have some drawings I was given, but they are not comprehensible to the guys I went to for a cutting quote.
    Some of the stuff is in Autodesk which they can't work with but a bit is readable for them. They will be able to cut but not bend.

    Lol, that post of mine was in 2013.
    Since then I looked a few times at a few packages. Found FreeCad, and only after a few hours starting picking up a few videos where guys were saying its too comprehensive for beginners.
    Then about a year ago with Covid, I was forced to look at something again, and found the old 2017 free version of Sketchup and got stuck in. I'm still learning every day, but have managed to put a few drawings together for our building sites where we do Timber Frame houses. I had to do something to "protect" us against some of the "bright ideas" some structural engineers were bringing to the table. I'm involved with a house now where I came in very late, and the present builder has never done timber frame before. The engineer has added weeks of additional work, and more than tripled the cost with way out ideas that actually dont work.

    Anyhow, I'm learning, and in the back of my mind know that it's time to move on to something more current like Fusion, or bite the bullet and pay up.

    I do have a problem that it needs to run on my 2008 vintage P4 with 4Gb of Ram and a 1Gb video card.

    Isnt fusion very expensive and not a once off payment.Its fine for a business but to dabble for the odd drawing prohibitive. What other programms are there if my statement is correct?

    Fusion is free for the basic DIY'er. Some limitations but nothing you can't do without.

    Before selecting any drawing package you need to answer one question: Can you draw? I do not mean to draw/paint Mona Lisa but technically. Let say you draw item to be made using lathe. Before you start you actually have to know how lathe works. The part has to be right way on the drawing. After that when adding dimensions you have to give them so that the design intent will be achieved without calculator in the hands of the lathe operator. Tolerancing, surface finish symbols... Same applies what ever you draw.

    I have tried several times to find a good book or books in English that teach how to draw. Up to now I have not found one. Some drawing standards are not bad but they are not really learning material.

    Selecting a packet to use is problematic. Some are good for industry A, some for B. Very few are cheap many are horribly expensive if properly licensed program is bought. In today's world 2D is for simple items. 3D reduces design errors but pretty 3D image is no good for making the parts. You need 2D drawings out of the 3D model. Bigger packages include FEA to analyze stresses but you really have to know what you do if you go for that.

    If you can draw by hand on average it is 6 months to get to the same productivity level using CAD package. Spending time learning some tricks, building parametric libraries you will do designs much faster and far less mistakes. On some special products I can get drawings out in hours instead of days. I could draw but to learn use of software I had to go in steps. First 2D, simple 3D and at the end complex 3D. That included around 10 000 pages in literature - Thanks to Amazon I did get the books. Today I would start directly at 3D. Packages are much better.

    I have big problem with computer operators. They make pretty pictures but useless output. They cannot draw and they do not understand what the numbers mean. Last week I was asked how to design expansion joint when movements are 0.45, 0.56 and 1.35 mm and angulation 6.3987 degr. Who ever gave such values has no idea.

    If you require high quality drawings and you have limited number of parts in your assemblies go for Autodesk Inventor but first rob a bank. (Mechanical items - not buildings)

    Very well said. The workshop wants 2D drawings with dimensions and tolerances within their capabilities.

    I also use Inventor Pro, as the total path from solid modeling, Nastran FEM, CAM to CNC machine works really great and the yearly subscription is kinder to the budget than paying for all of that in a once off payment for Solidworks and its modules.

    It was a long time back, but I did drawing as part of Metalwork at school and then after at Technical College, so at a fundamental level, I can draw.

    I have been given a copy of TurboCad15 and I have seen what it can do in the hands of a knowledgeable person, and it is all and more than I would probably WANT/NEED to do, but the problem I have is in my pip where I struggle to make the connection between random icons in the menu and the pencil/square in my hand/mind.

    I have roughly 17 years experience on Inventor and 5 years on Solidworks.

    Solidworks is far more powerful for sheet-metal. Especially for developments including rolled rather than bent sections. It is also better at carrying over dimensions from an assembly to it's individual components.

    Inventor is easier to learn, and better at seeing how a mechanism operates. The biggest difference though is that Solidworks makes it far easier to make versions of an assembly which are similar but different.

    But the differences are relatively small and either will allow you to do good work.

    I use Solid Edge - very good and versatile, but expensive to buy. I agree with Jouko that if you haven't drawn before you will struggle to learn. You also need a basic knowledeg of machining, tolerances etc to produce good 2D drawings for the machine shop.

    Solid Edge do offer a very good free 2D package - Google www.solidedge.com. It downloads with their free viewer.
