Interpolates elevation values along a non-aggregated linear feature from a starting value to an ending value.The resulting feature’s elevation will monotonically increase (or decrease) from the starting value to the ending value.
Input Ports
Input
This transformer accepts any feature. Only linear features will be affected.
The elevation of an arc is interpolated on its defined end-points and possibly mid-point (if the arc is an arc by 3 points).
如果该功能是二维的，则它变成了三维。
If the feature was three-dimensional, its previous elevations are removed and replaced.
Output Ports
Output
The features with interpolated elevation values.
Parameters
You can enter the parameters as a number, or choose them from the value of a feature attribute by selecting the attribute name from the pull-down list.
Starting Elevation
The elevation value for the first vertex of the input feature.
Ending Elevation
The elevation value for the last vertex of the input feature.
Usage Notes
TheSurfaceDrapertransformer (available in FME Professional edition and higher) can be used to supply interpolated elevation values based on a 3D grid or set of 3D features to the vertices of two-dimensional features.
Editing Transformer Parameters
使用一组菜单选项，可以通过引用工作区中的其他元素来分配变压器参数。一些变压器也可提供更高级的功能，例如高级编辑器和算术编辑器。要访问这些选项的菜单，请单击

Defining Values
There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.
How to Set Parameter Values
Using the Text Editor
The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.
Using the Arithmetic Editor
The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.
Conditional Values
Set values depending on one or more test conditions that either pass or fail.
Parameter Condition Definition Dialog
Content
Expressions and strings can include a number of functions, characters, parameters, and more.
设置值 - 无论是否直接在参数中输入或使用其中一个编辑器和包含字符串的表达式都是构造的，都会评估这些函数的字符串和表达式。因此，这些函数的名称（以@ <function_name.>) should not be used as literal string values.
Content Types
| These functions manipulate and format strings. | |
Special Characters |
A set of control characters is available in the Text Editor. |
| Math functions are available in both editors. | |
| Date/Time Functions | Date and time functions are available in the Text Editor. |
| These operators are available in the Arithmetic Editor. | |
| These return primarily feature-specific values. | |
| FME and workspace-specific parameters may be used. | |
| Creating and Modifying User Parameters | Create your own editable parameters. |

Table Tools
Row Reordering
|
Enabled once you have clicked on a row item. Choices include:
|
Cut, Copy, and Paste
|
Enabled once you have clicked on a row item. Choices include:
Cut, copy, and paste may be used within a transformer, or between transformers. |
筛选
|
Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output. |
进口
|
进口populates the table with a set of new attributes read from a dataset. Specific application varies between transformers. |
Reset/Refresh
|
Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers. |
Note:Not all tools are available in all transformers.
