I'm new to Blender, and am building a flat surface to be extruded later (submarine deck).
I've designed an outline as a Bézier curve which I then converted to mesh. After that, I iteratively created the slots in the deck in the same manner. For convenience, I have placed the slots into groups, as you see, tagged with suffix numbers from 0 going left to right (stern to bow). Groups 0, 1, and 4 have been successfully integrated.
However, I seem to hit a brick wall at this point. When I try to add new slots (in this example, group numbered with suffix 2), the fill seems to break. I've tried different groups and even just tried to add single slots, to see whether one of them is somehow improperly designed, but I can't get past this point:
Is it likely something about the individual slot construction? They were all built from the same template, just adjusted in length....
Note: not sure whether it matters (like in fonts) but the outside outline was a clockwise curve, the two hatches (not joined here) are counterclockwise, and the slots were created using the circle curve feature and not altered.
EDIT: following suggestions below, I was able to achieve near-complete success (all but four slots of several hundred), as follows:
- Build a clean main object.
- For a given group of slots, create and apply a boolean 'difference' modifier in a similar fashion.
- in a few cases, some fiddling about was required such as making groups smaller, doing them in a different order, or using 'face' rather than 'fill' before extruding the modifiers (though in most cases it made no difference).
- End result:
- note: after each application of a difference modifier group, I checked carefully for quirks in solid mode then examined the mesh in detail in wireframe mode; if I saw anything out of the ordinary I backed up and tried something else.
- Ultimately, I was able to produce what I wanted and a clean (as far as I can see) topography, except for 4 slots where the boolean differences failed no matter what I did. I understand that these can be fussy, and I tried every trick I could find on the internet with no luck. But I think the last four can be done perhaps at the wireframe level (?) and can open another topic for that.
