| Summary | 0001846: impossible fusion on complex objects | ||||
| Description | For complex objects (>50 simple objects) the fusion can give an unexpected result. Some parts do not appear, they are just contained in the fusion object. | ||||
| Steps To Reproduce | open/import a complex file such as http://www.optics-focus.com/download/3D/Motorized%20Translation%20Stage/MOX-03-50.rar select all simple object clic on fusion button wait a long time | ||||
| Additional Information | Sometimes do fusion by steps works: select 5 obj->fusion; select 5 obj->fusion... then select fusion object two by two and fuse them until it remains only one. | ||||

I can't open the attached rar file (Unsupported Method) |

This looks like an assembly on non-intersecting solids. Don't see the point of fusion. Be specific on what items you are trying to fuse. |
|

@shoogen: the rar file contains a step file @tanderson69: I used the wrong term, in english it is called union. Anyway since there is not the assembly by default on the debian build, I use union to create an assembly. I works in general, even with separate parts (you can try with 2 separated cube for instance), but not when it start to be to complex. On my opinion, or it should work in any case, or, if it is not the expected behavior, the union of separated object should not be allowed. |
|
|
Fusion/union is for intersecting geometry. Using it to make an assembly is a bad workflow. If you want to combine shapes into one use make compound from the part workbench. |
|
|
I agree with tanderson69. Shouldn't this report be closed as invalid then? |
|
|
I was waiting to see if he would post back again....but yes I think this could be closed. |
|
|
I agree to the invalidity of the question, but there is still an issue for me: The fusion between two object that cannot be fused should not be proposed. The same for the other binary operations. |
|
|
That is really not possible. You basically have to call the boolean operations and test if they succeed. We can't be doing that during responses to selection changes. Way too slow! |
