There is a Duplo stud shape in between stud8 and stud28, i.e. where the inside has two straight segments on opposite sides of the circle. Stud8 has no straight segments and stud28 has four straight segments. The 2-straight segmented shape occurs at least in the picket fence 6497. I'd like to create the 2-straight segmented shape as stud38. Any objections?

Another variant has 4 small notches in each of the 45, 135, 225, and 315 degree angles. Occurs at least in the ladder 3519. Would be convenient to have such a stud primitive on hand.

Edit: Corrected stud8 name.

Deleted content because the info was wrong.

I find myself repeatedly adding edges and discs of the same size and shape. Would it be useful to have a 'disco' series similar to the cylo series?

This is the part number, any help is massively appreciated. I believe it is available in the lego builder app already so if that makes it easier

ConvertToLDraw is a Software I created to convert a variety of 3D file formats to the LDraw format.
Here are some of its features:
-load formats with colour and submodels
-edit the colour of subparts and multicolour objects.
-textures are converted to vertex colours.
-3D preview of the part

The software has 3 tabs.

The "Main Part" tab containing the import/export and the metadata settings:
   

The "Colours and Subparts" tab here the names and colours of subparts can be changed:
   

The "Part Preview" tab shows a 3D view of the main part or a subpart:

This part is in Lego Builder so it should be easy enough to extract for someone with the app setup etc. The instructions that have the part are for set 75361-1 Spider Tank.  It is also in set  75374-1 Onyx Cinder.

Thanks very much if someone gets chance to extract it.
