View Full Version : Boolean operations in FSDS3
07-01-2007, 09:14 PM
I'm trying to build a ship in FSDS3 and this needs circular ports in the main breakwater, and will also need other ports elsewhere (when I get that far....)
I've got the breakwater built OK, made of lots of FSDS boxes joined together, and now I'm trying to 'drill' the ports through its front surface. I've developed the tube 'tool' OK to drill the hole, and positioned it correctly, and closed the ends, but having done the 'Ctrl-B' to do the Boolean Op, whatever I do I do not end up with a hole in the breakwater!
It seems to be something to do with which parts need deleting, but he Help files are anything but! They tell you delete everything, which obviously can't be right.
I've tried this with a simple box and tube and it works, so why doesn't it with my more complex breakwater please?
Anyone any ideas?

I am not a expert but I can give you some help,on the boolean operation. In fact it is quite simple really. Just follow these steps.
1. Make a box 20h x 20w x 2d - this is the main part.
2. Make another box 5h x 5w x 10d but call it tool because this is what you are going to use to cut the hole.
Note - these dimensions will make it easy to see what you are doing.
3. Place the tool part where you want to cut the hole.
4. Now using the arrow keys select the box. This is important.
5. Then go to the Part Menu and select both parts by name. Click OK.
6. Part Menu again. Choose Boolean Operation.
7. If you go to the Part Menu and the Choose part by name you will see you have more parts than you started with.
8. On the right side there are the 2 original parts. On the left are some new parts. All the parts named tool should be placed on the right side.
9. This will leave you with 2 parts both with _bool added to the name. There is a part with box_bool1 and a part with box_bool2.
Note disregard the numbers in brackets.
10. The part you want to keep is box_bool1 - so select the part with the box_bool2 and put it on the right side.
11. This will leave you with 1 part named _bool1 on the left side
12. Now having clicked Ok to select all the parts listed on the right side, hit the delete key. This should leave you with a box with a nice square hole in it.
13. The secret if there is one is this. To be sure that you are going to leave the correct part on the left side, deselect all the parts then select them one by one and make them the current part as you do so (As I said before, you can disregard the parts that have tool as part of the name). As you go through them one by one (there is actually only 3 parts that you are concerned with anyway) you will see straight away which part is the one you want to have at the end, and this you leave on the left side. The rest you delete!
Don't try to do more than 1 boolean operation at a time. Save, exit and start again to be safe.

It works just as you said, thanks.
Now I have some idea about what to do, so I can get back on it.
