So this is the situation: You are using a generic model adaptive family. The family contains one model line, only, and this line has an equal-equal constraint to the horizontal plane. But when you load this family into another family or into a project, the insertion point of the family is not the midpoint of that line.

This is the reason: in this template, generic model adaptive, the two reference planes in the plan view are not pinned by default, and the insertion point of the family is fixed (like the internal point of a project). Even if you move those reference planes, and even if you define other reference planes as "Defines origin", the insertion point of the family will continue to be the same fixed point, which is the intersection of the reference planes at their original location. The only way the insertion point of the family changes is when you create an adaptive placement point. Then that point becomes the insertion point of the family. If you place more than one adaptive placement point, then the first point will be the insertion point of the family. If you have several adaptive placement points, and you renumber the points, the point marked with the number 1 is the insertion point of the family.

Did the origin of your adaptive family move? It looks like it did, but it didn't. The origin is the same fixed point, because the family does not contain adaptive placement points. What happened was that the original horizontal reference plane moved down when you did the equal-equal constraint because the two dimensions (before using equal-equal) were not the same.

How can you avoid this in the future?

• Pin the horizontal reference plane before applying the equal/equal constraint.
• Or... create the two new horizontal reference planes at equal distances above and below the original horizontal reference plane, and then create the dimensions and the equal-equal constraint.

How can you fix this family? Please refer to the illustration below.

• Image #1 shows how the family inserts in another family or in a project. Notice that there is a distance of 0.093 decimal feet between the midpoint of the line and the insertion point.
• Image #2 shows your adaptive family. Here, you are going to unpin everything and then move everything up 0.093 decimal feet. Then load the family again into the other family or project.
• Image # 3 shows the adaptive family inserted into another family or project, with the insertion point at the midpoint of the line.

Thank you so much. Finally i got an answer after a long time.

Again Thanks
