Question
Profili 2 - which version?

I am a novice CAD user (TurboCAD 19) and admittedly, my downfall is trying to draw a decent wing rib.

I just downloaded the free version of Profili 2 and have been playing around with it. It looks like it's just what I need, but I'm unsure of which registered version to purchase.

I want to be able to draw my wing ribs and export the file in a format that my TurboCAD program can use. I've tried looking through the help menus in Profili, but am still a bit confused.

Any help from Profili users would be appreciated. Thank you!

I have Profili Pro 2, version 2.30a. I have the "Pro" version because I use Profili to make stuff which gets incorporated into designs I sell. I suppose I should update to 2.30b at some point.

Get the USB key version.

You can se here http://www.profili2.com/eng/features.asp the features enabled for each version of Profili.
But if you main interest is in creating ribbed wings the suggested application is devWing, see http://www.devcad.com/eng/devwing.asp. You can see here the features enabled for each version of devWing http://www.devcad.com/eng/devwing_features.asp

If you don't get the Pro version of Profilli then you are just wasting your money. Even the XT version does little more than allow you to print. Only the pro version allows you to export DXF. Most if not all of the DEV programs are no more than high priced demos unless you pay for the Pro versions. It's why I stopped buying them. By the time you pay for all of the Pro versions you could have bought Rhino or full up Autocad and saved some $$$ in the process.

An original point of view. The cost of Rhino + Autocad is about 10 times the cost of the bundle of the ALL most featured versions of dev applications. Or may be in Italy Rhino and Autocad are overpriced.

The update is for free, just download and install it. Since the first release all the update of Profili, Profili XT and Profili Pro are for free.

It's only because I haven't bothered to do it, but you make a very good point. I've been a happy Profili customer for probably 10 years.

where do you get them i not so long up dated my acad 2010 to 2015 1630euro
rhino with Tspin 698euro for student licence may be haft price but her you have to prove your age to get it
and they do not ever thing that dev software can do for some one that has not spent a lote of time studding cad sofware so if you add all the time you are well over price

Profili pros and cons.

I don't have the "pro" version and mine does allow exporting of .dxf files! This is something that I use and rely on fairly much all the time.
I must admit, it is confusing and difficult to ascertain which version will suit your needs between the various products offered by Stefano.
I have used the Profili2 version 2.30a for hot wire cutting of foam almost exclusively for some years with success. There are some inaccuracies, but mostly it is quick and convenient for this job.
However, what was not clear to me at the outset was the compensation factor for the wire kerf size that is factored into this program. This only became a potential problem or concern when I went to use it for creating templates for uses other than hot wire cutting.
I have not explored the rib drawing potential of the version that I have. It may do the job, but I can't tell.
I've not had good luck with my communications with Stefano sad to say and this has put me off purchasing any other products from him; good as they may be. (I am not the only one to report this).
Also, each of the Profili products are somewhat too specialised for my needs and could become redundant after one design use. I favour the more generic type of CAD program now days.

I use the script reading ability built into my CAD program...dl the dat file for free off the web, and let the script function draw it directly into your CAD program....

That sounds like a very good feature. What CAD program are you using? Is this feature in AutoCad do you know?

However, Profili2 will process, mix airfoils and run polars. That is a feature I would not be able to do without. I understand that XFoil is capable of doing this, along with a couple of other programs, but I have no experience with them.

You can find many freeware applications to draw a dat file at the right size.
The most difficoult thing is then for example to create lofted ribs with differents airfoils at both ends, complex wing plans, apply sheetings and other components like spars, leading edges, trailing edges, aileron and flap slots and so on.

I'm pretty sure if you register and pay for the software it will provide full functionality of features listed in the "Features" page. The demos are not shareware and therefore, limit output features. You can perform all the tasks related to design and VIEW the results.

I really don't think you could buy a full up, non-student version of Autocad for the cost of the hobbiest's licenses of the Pro versions. I don't know about Rhino. Of course, the commercial use Profili licenses are significantly higher.

The above statements are expressed solely as my opinion and in all probability will conflict with someone else's.

Jim,

I use both AutoCad but lately I've been using DraftSight (free version 2D), both have this feature. The system I use works best with a constant airfoil with different chords (tapered, eliptical, etc..) Very easily pumps out different chord lengths. It is not automatic except for the script read but it's very easy once you've done it. Harder to explain than talk about on here...lol It can also be used, with a bit of work, to adjust for progressive thickness.

But, as you suggest, it does not produce polars and would be cumbersome to mix airfoils.

durone,

Complex shapes are no problem but it does not work well for mixing airfoils. As pointed out above, it works well on any wing plan I've run across or wanted. Even adjusts thickness if wanted. It is not an automatic process but easily does sheeting allowances, spars, leading edges, trailing edges, aileron and flap slots and so on

And, you're correct, many programs (freeware) do this....I prefer to do it within my CAD program. I've found it works well for me, but others may differ....each to his own....

These are essential features for me.
Ideally, I would have an airfoil processing program like Profili2 or XFoil et.al., and a proper CAD drawing program like AutoCad (which I can't afford).
I started out with DraftSight, but soon dropped it due to far too much span emails and poor online forum assistance. I've been using LibreCad 2D with some success, but it is not good enough for some drawings - inaccurate snap functions etc.
Sorry if this is a bit offtopic.
