Thanks marcus_civis and sirquadalot.
Digits I downloaded the one in your post.
A few questions
1 do you load the tool first then go to edit then load the plugin? or do you load the plgin then the base tool then use the plugin to design with? If you load the tool in the plugin just have marker turned on before placing it onto the canvas?
2 When done using the plugin with the markers do you make a polymesh of it or something else to get it as one ztl? and if so how?
3 can you place the plugin in plugins to have it ready in plugins when starting ZBrush?
