Hello Friends,

Studio Petrikas (twitter: @MPetrikas) has really good tutorials. I have learned how to connect two surfaces with G1 continuity, and it makes a huge improvement in my neck to head transitions:

Here is the example file:

Transition to barrel continuity is still a work in progress, but the transition surface itself is now G1 continuous.

Next release of Marz Designer (aka Marz Workbench) is coming soon.

Hi Chris,

This is the current status, almost perfect continuity but 2 remaining seams to be solved. :(

I have not started the migration of the Body Part yet, compared with Fretboard+Neck the Body code is almost trivial :D But I wonder if users want some preview version without Body generation. I need to do a lot of work on the UI before releasing anything but I can just continue with the CAD code of the Body and work on the UI later or work on the UI now and on the Body later.

Hello guys,

here is the next starting luthier. I'm curious to see if I can realize my first construction project with freeCad.

I started with partdesign and it seems I could realize a certain bodypart for a bass guitar quit well.
In the meantime I have understood how difficult it is to construct a perfect neck with all the transitions.

mnesarco, your Marz workbench is great. I have to donate ... :)


Do I already need your help?
I have designed a headstock in inkscape and want to import it into my project.

freeCad (0.19 on win 7) reports:
"The svg. file does not contain any contour path. make sure you have a path with id=contour."
"Document has 0 guides"

I went into the xml-editor and distributed names to each single object (so that freeCad can recognize them?).

Now the message on import is: "Some data is inconsistent or impossible in Instrument parameters."
Midline and contour should be named correctly now.

I hope you understand my problem as a half-DAU. ;)

Big thanks to the developer and greatings to all designers. :)

Thank you, take into account that the Marz Workbench is outdated and limited. But you can use it as an starting point.

In order to import svg designs you need to follow some rules, here is de doc: https://github.com/mnesarco/MarzWorkben ... tom-Shapes

you can also download the sample svg files to inspect them.

Cheers,
Frank.

Hi Frank,

sorry for calling with your nick.
Thanks for the link. I will work through the data.

You write, FreeCad is outdated and limited?
What are your recommendations how to create a 99 % perfect neck with CAD?

Best -
Michael

Just tried your online version.
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.
