Quick Circle Break

Just a quick idea came to me, as I remember having to break a lot of circles to show hidden lines etc on drawings, so this should make life a lot easier for you guys

He makes a point, CADTutor members should get it 50% off, and then charge super cheap prices. And you pick testers (that you trust not to give it away free) to test the LISP.

I know Mark :wink:

I figure that even if I start charging for code, others will provide if free anyway.

Then you are determined to give away more code than anyone else right? Dang! You are a mastermind. You need to meet with Donald Trump.

If that isn't sarcasm, then I don't know LISP ... :wink:

Thanks mate, you're not too bad yourself

I have to say that this isn't a bad little app. Very nice work, again.

I figure that even if I start charging for code, others will provide if free anyway.

May i suggest you aleast put headers on your programs

With your programs, Are we able to distrubute them to others.

Because there is a few good ones, which some of my colleges wouldnt mind using im sure.

P.s update your pipe drawer for all pipe sizes

Thanks Flower,

I do put headers on the main programs that take a bit more insight to create, but not normally on these small ones

As for the distribution, with the header in tact, I still own interlectual rights to the code - as implied by the copyright. But I have provided it for free, so you may let your colleagues use it also - as long as the header stays in tact.

But I am rapidly changing my view on this approach. I don't think I will offer programs freely in the future, but rather for a small fee.

but rather for a small fee.

Have you ever considered contacting a company like dotsoft and seeing if they might be interested in some of your code? For a price that is.

I haven't contacted any company regarding my code, but I think its definitely worth a shot - they can only say "no"...

One thing before you start charging for programs.

Can you add options to to change user selected circle part to hidden layer?

I’ve also wondered what the most efficient process would be to offer routines for sale.

Certainly the industry specific add-on packages are lucrative enough to justify the necessary advertising, web sites, merchant accounts, etc. For more modest sized offerings, however, that’s a lot of overhead to recoup before a break even point.

It would be nice if there were some clearinghouse style of setup, employing PayPal perhaps, that would allow the sale of routines at a modest price without the whole process becoming just another expensive hobby for the programmer.

haha, I wondered when I'd see this request

You have hit the nail on the head Sean.

At the moment I am charging a small fee to make LISPs on request and am using Paypal to sort out the business side of things. But, of course, this is only through emails - not a professional website etc.

I would like to make my own website, but, to get it right and how I'd want it would take a lot of time, especially since I have no experience with website creation...

I'm not really sure how much I would sell the routines for if I did decide to put them all on a site - I suppose this would depend on the functionality of the routine. I've seen routines out there selling for around £50, but then others (bigger programs - but still LISP), selling for around £750.

I think if I am going to proceed with this, I will have to make my own website, or get a friend to make me one - otherwise I am just lost in the forums...

Thanks,

Lee
