Short description of error

by creating bolts, using metric units: cm
I'm not able to set a pich bellow 10 cm (see attachments)

Exact steps for others to reproduce the error
my standard setup is:

set scene on metric units .
length on: cm. (I model in real sizes)

on adding a bolt (shift_a):
settings like attached .png
it is not possible to set pitch bellow 10 cm

The add-on has for some reason set a hard minimum for this property (bf_Pitch). I'm not sure if there is any particular reason behind this choice. The entire default scale is incorrect with the add-on though as with default unit settings it creates bolts that several meters long, so perhaps if this issue would be addressed the given limits would be wide enough for practical use.

@spudmn @cwolf3d is there any particular reason for this limit and the incorrect scale?

Hi

The entire default scale is incorrect with the add-on though as with default unit settings

Yes that is a problem with bolt factory. When it was written there was no concept of units in blender.

If you can point me to how I can obtain the units setting for the project I can scale the bolt to the correct size. When this is done then I will check the hard limits make sense.

OK I found how to get the unit_settings.

      print(bpy.context.scene.unit_settings.system)
      print(bpy.context.scene.unit_settings.scale_length)
      print(bpy.context.scene.unit_settings.length_unit)

I will look into scaling the model correctly

This should be marked as a duplicate of #83322. Addon was written before internal blender units were standardized to 1m, so author assumed 1mm… so minimum pitch of 10cm was actually intended to be 0.01mm
