Not a problem.

I never said that. What I said is that Marz Workbench is outdated and limited.

When importing a downloaded file I get the same error "The file does not contain any contour path. Make sure you have a path with id=contour."

FreeCad version 19.1 on Win7 may be the basic problem.

Hello Frank,

sorry for mixing up FreeCad and your Marz workbench generally. Was not intended, bad mistake.

Thanks for your attention and the resent file.
At first I did not fill in the correct IDs of my headstock.
And I probably had created an unfavorable position for the transition line and that's probably where the last error messages came from. Will find out.

But now I have my neck on the screen. Wow - that's awesome! :)
I'm curious how it goes on.

What can I do for you Frank? I am no progger or so. Do you want a guitar or bass? ;)
All the best -
Michael

Thank you, it is good to know it worked for you. The transitions in the Workbench version are very ugly, but they are a lot better in the current development version. Unfortunately It is not public yet, but it will be.

Thanks for the offer, very generous. At the moment it is very satisfactory for me that you can use the workbench.

Cheers,
Frank.

Hi Frank,

thanks for the infos.

what are your goals for a release date?

How can users reward your work?
Would it be a good idea to release it as a software package at walmart? ;)

Your workbench allows setting the neck angle to zero degrees. This is the way the most bolt on necks are made.
But there is no heel at the back of the neck. You know that.
Fender want(-ed) it cheep. Only 19 mm (ok, 20 ;) ) thick maple blanks needed for a bass neck.
At the moment the volute radius does not fulfill that demand. One has to set it to ~ so to say.

A 3D print will be started soon.

I'm really curious how your optimized version will be.

Have a nice weekend.

Cheers -
Michael

I am on Win 7 too.
Any doubts not to update to Win 10? Problems overall with win7?
My systems seems to run well and I do not want to change my working system.

This is a side project, I have no hard deadlines.

I still don't have commercial plans. I will maybe release it with a very cheap perpetual licensing, or just make it free with option for donations.

Yes, it is solved in the dev version (support for flat/no volute)

You can see some progress here (a little outdated now):

Hi Frank,

I now have two test pieces in 3D printing and I'm really excited to see whether it will work.
One should not cause any problems, as there are no transitions.
The other is a neck, first try. That's going to be hard...
The volute is at max, which is pretty flat at the bottom.

The result in the universe does not have to be perfect, as a little manual work will not hurt. But if a monster comes out of it, that's different.

Of course you don't have a deadline. May I ask about your personal time goal or target? Or are you not going to reveal that? ;)

In fact, the question for me is just about coordinating my own plans.

Can you rethink the transition at the base of your neck? (I'm speaking here as a layperson, aren't I?) Simply round or oval does not quite correspond to the spiritual requirement. Do you know Fender neck feet or something licensed from them?

Wish you a nice weekend.

It would be great to see the outcome.

I think i can release an alpha or beta version this year.

I am not sure that I have understood what do you mean here, but the transition algorithms used in Marz Workbench (FreeCAD) and the current dev version are totally different, the new algos are Bezier based.

- if my outcome arrives I will post it.
- a release this year would be great!
- transition ...: Bezier based algos make a difference. Got it.

I wish you much success.
