Merge Results Issue In Chain
Whenever we create a chain model, we want three different bodies in the entire model: pins, outer links, and inner links..one should not be merged or combined with the other.
Merge Results Issue In Chain
ISSUE: While creating the curve-driven pattern in the chain. While selecting the pins, the other bodies, like links, are also getting selected.

NOTE: whenever we are creating a chain model, we want three different bodies in the entire model, they are pins, outer links, and inner links..one should not be merged or combined with the other.
1. PIN

2. OUTER LINK

3. INNER LINK

MERGE RESULTS:
1) Merge results or merge solids is the option that is used to combine the two separate bodies into a single body if they are in contact with each other.
2) This merge results option will appear in the boss extrude command.
3) For example, if we consider a chain model while creating the pin and link, both are in contact with each other, when we click on the merge result option, we can observe that both the link and pin will be combined together as a single solid body even though we are creating them as two separate bodies.


4) If we are deselecting on the merge results, then we can observe that the bodies that we have created will not be combined into a single body.


Procedure:
1. While creating the outer link, inner link, and pins, we should deselect the merge results option to create these bodies as separate bodies.

2. If we are selecting the merge results option, we will be combining the links with the pins.
3. When we do that, we will not have a separate link and pin anymore, both bodies will be combined into one body.
4. Due to this reason when we are trying to select the bodies for doing the pattern, multiple bodies are getting selected.
5. So whenever you are facing such an issue in selecting the bodies for the curve-driven pattern, try to deselect the merge result options for all the boss extrudes before doing the curve-driven pattern.
6. After deselecting the merge results for all the links and pins, if you are doing the curve-driven pattern by selecting all four bodies(two pins and one outer link, and one inner link), your preview will look like this.


CONCLUSION:
As mentioned above, while creating the interlinks, outer links, and pins, we should always uncheck the merge results option while using the boss extrude command. Check out this course to know more about the Merge Results in Chain.
