Hola , Booleano
Un taladro está compuesto por numerosas piezas (aunque no quieras modelar las piezas internas que no se ven).
Antes de continuar con el modelado, sería conveniente, de cara a lo que viene después, realizar varias tareas:
- Nombrar todos los tipos de objetos que crees.
- Posicionar el taladro según los ejes X, Y y Z del software; esto permite gestionar mejor el modelado. Un taladro es, en general, simétrico con respecto al eje Z.
- Corrige algunas curvas de la parte central (en verde) que están distorsionadas; consulta las capturas de pantalla adjuntas.
A continuación, podrás concentrarte en la operación booleana que desees realizar.
Por mi parte, tomaría fotos (o las conseguiría si fuera posible) de las cuatro vistas de la taladradora para tenerlas como fondo en MoI 3D.

Pero no sabemos cuál es tu objetivo final?

Hello Boolean
A drill consists of many parts (even if you don't want to model the internal parts that aren't visible).
Before continuing with your modeling, it would be helpful for the rest of the process to complete several tasks:
- Name all the object types you create.
- Position your drill along the software’s X, Y, and Z axes; this allows for better modeling management. A drill is generally symmetrical about the Z-axis.
- Correct certain curves in the central section (in green) that are distorted; see the attached screenshots.
Then you can focus on the Boolean operation you wish to perform.
For my part, I would take photos (or obtain them if possible) of the four views of the drill so I can use them as a background in MoI 3D.

But we don't know what your ultimate goal is?

Hi Zooen

Sorry, the file is corrupted. I'll correct it and resend it.

Thanks

Hi Booleano, looks like a quite difficult job to do by drawing. A reverse engineering tool would probably work better.

Do you have the actual object or only photos?

Hi Zooen

How did you get that "transparent" image of the file so I can check for those defects?

I'd appreciate it if you could help me get it.

Hi Michael

After trying many operations like copying and pasting and using two masks, I've gotten this far. I've attached the two files.

I think my difficulty lies in determining where to place the pivot point.

All images already published are valid

Thank you again for your help.

Hello Booleano,

To answer your question, these aren't your three transparent solids. It's an extraction of all the edges from those three objects. The result is a wireframe of all visible objects.
To perform this extraction, you need to use the “SelectByType” script.
Below is a link with instructions.
