    Default Flat Pattern in AutoCAD?

    Registered forum members do not see this ad.

    Hey folks,

    A mate of mine has gotten in his head that he wants to weld a boat.

    yeah I know, very hard, has to know how to weld (and in aluminuim which we have learnt is not easy) and yada yada. But if we remove all those obstacles, the thing that he's concerned with right now is how to do drawings for it.

    I have recommended that he explores Inventor and the Flat Pattern function which to me seems like the best way to go to get the pieces of the boat the right shape and size.

    But he doesn't know Inventor, he knows AutoCAD though and now the question is if there is anyway to do the Flat Pattern-thng in AutoCAD. Or how would You go about drawing an aluminium boat in AutoCAD - and how would You get the drawings out of it?

    A loose question I know, and I expect more along the lines of ramblings than answers - but it's ok, we are all rambling here anyway

    Check which formats is AutoCAD able to export, respectively Inventor able to import. Maybe will find one supported by both.

    The thing is he doesn't want to use Inventor, he knows AutoCAD so it would be easier if he could do this all in AutoCAD... but I have no idea how he would go about doing it

    Will he bending pieces?

    I've had our fabrication shop weld up aluminum ladders and frames once in a while. The shapes used are similar to steel and they use of combination of fillet and full penetration welds.

    The actual welding I have no idea about, there's been a lot of mig and mag and tig thrown around - I am more consulting on the CADding part of the project.

    The pieces will probably have to be bent. after all the boat is round-ish-ed. And that is the problem - if you do a 3D-model, while difficult (at least for me) is not the problem, the problem is to present the 3D-model in such a way, divided into parts that they can be cut.

    I've dealt almost exclusively with flat stock (no bending required). I guess I won't be of much help to you and your friend then. Sorry.

    Maybe JDM can suggest something although he does like to remind everyone that AutoCAD is old school and Inventor is the future. Unfortunately not everyone wants to or can afford to make the jump.

    Maybe your friend can download a trial copy of Inventor and literally knock out his boat in 30 days or less (before the trial runs out). LOL

    Oh we have Inventor at the company, so there is really no hindrance for him to learn it his leisure - even at work since there are talk about migrating to Inventor for the whole division - but you know.... old dogs and all that

    I've used their unfoldsurf for a complex curved plywood structure and it worked like a charm. You can demo it for a few days to see if it will work for your friend.

    If you spend lots of time on workarounds to get the job done in AutoCAD how can you afford not to make the jump?

    Uhmmm, if the tool you have won't do the job how can you afford not to make the jump?

    This could be a real challenge even in Inventor depending on how the plates are bent. Bending yes, double bends maybe, deep draw forming, no. Can model it but might not flatten without add-on program.
