problem with boolean union and subtraction

[lizardluc]

Hello everyone, I am new to this forum and I would like to ask a hand for how to solve this problem.
I have my hull and I can't do anything well in Boolean unions and subtractions, is there something? in the above part I have those parts to remove to the big hull but always tells me: Boolean difference failed.
I attach under a photo, also because I don't know how to send the document in the annex.
Thank you very much in advance

ciao lizardluc,Boolean operations work between solids.
if you use them between surfaces, or between a surface and a solid, you will get nothing.
note: to create a solid it is not enough to close all the surfaces, it is also necessary to tell rhino to consider them as a "unique body", for example, using the "createsolid" command.

to attach files to the post you have to click on the button "go to advanced mode". when you will upload the advanced editor will appear the icon to insert the attachments (it is close to the one for the "smiles", and has the form of a paper clip)

I hope I've been helpful.

I tried to make solid creation, but also it gives me impossible.. Now anyway I try to put the file here so maybe you can better help me (always if you can). are the first weapons and it is really complicated this program

I took a look at your file.

In fact, it seems that you are at first arms not only with rhino but also in modeling 3d, not to take it as a criticism but well as a statement (we all started making your own mistakes).

I can only give you advice

1) from good curves (a few points and regular) good surfaces arise (reduced number of isoparametric and regular)
2) two surfaces will join only if the joint edges are within the general tolerance set.
3) before dealing with complex projects, try to do many tutorials that you can find on youtube and on the net, so that you can well deepen the use of rhino commands.

4) Boolean works only if you work on polysuperficies that contain closed volumes, those that are commonly called solids (to understand us: even the smallest hole causes them to fail)


In the annex you can find the file that I have processed, trying not to disconnect me too much from your curves and therefore keeping some initial defects.
Now the hull is a solid on which you can do boolean operations.
