Question
I want to set the Point Library to be linked to the alignment.
Answer
You can use Constraint Array Point to allocate Point Library to upper mode.
In the case of Point Library, in order to be linked to the alignment change, it must be assigned to the Assembly Unit and used.
Let's look at how to link all alignment changes when working with one or several objects with one Point Library.
EX) This is a method of arranging a point library to be repeatedly placed such as a street lamp in the assembly unit and interlocking it with alignment changes.
Setup workflow
1) Assembly Unit mode
: Constraint Entity > Point > Array point > Select the desired path type among Constraint path
(Default / Main / Rigid / Sub ).
2) Select Pattern type from Arrangement menu.
(Pattern Spacing / Uniform division / Uniform Max. Spacing / Uniform Min. Spacing / User Defined)
3) In the Direction menu, define the reference point of the Point to be assigned to the Path.
( Positive / Negative )
4) Assign library > Point > Constraint point (Point / Array Point) > Alignment ( Horizontal / Vertical )
to create an Assembly Unit assigned to the Point library.
5) Define the profile through Base > Layout > Create-Edit > Vertical Alignment
6) Check the type of Point library assigned to the alignment by pattern by going to
Base > Library > Assembly > Assign.

(Pattern Spacing / Uniform Divisions / Uniform Max. Spacing / Uniform Min. Spacing / User Defined)
The example below shows how a 10m curve library was created and assigned to a 60m alignment.

| Figure. 9 Uniform Max. When Spacing is set (Max. Spacing 4m) |
Figure. 10 Uniform Max. After Spacing is completed (Maximum spacing is 4m, equal spacing → Actual spacing of 4m) |
| Figure. 11 Uniform Min. When setting spacing (Min. Spacing 5.5m) |
Figure. 12 Uniform Min. After Spacing is completed (Minimum spacing is 5.5m, equal spacing => Actual spacing of 5m) |
| Figure. 13 When User Defined is set (3@2.0m) |
Figure. 14 After User Defined is completed (3 intervals at 2m intervals in the alignment → 4 columns including the actual viewpoint) |
Using the Minimum Clearance function, you can arbitrarily define the starting point and ending point of the point to be assigned to the path.
