Trimble Tekla Tedds 2021 SP1 with Library Update (May 2021)

Tekla Tedds 2021 - Service Pack 1
This service pack is required when using the Tekla Tedds Engineering Library May 2021 or later.
Important
If you are running a 64-bit version of Windows you will require both updates.

Eight new functions which can be used when writing custom calculations.
CubeRoot
Calculates the cube root of a value including support for negative values.
CubeRoot( 8 ) = 2
CubeRoot( -8 ) = -2
String List Functions
String list functions allow a list of values to be managed as a single string value where each item in the string is separated by the list separator (normally a comma). For example you might use such a list for recording the positions on a beam where results of interest occur.
The new functions included in this service pack make it easier to manipulate such data.
Example
Two separate operations have resulted in two lists of positions of interest on a beam which are not currently sorted, create a new list which contains all the positions (in mm) from both lists in order from smallest to largest without any duplicates.
a1 = 0.0m; a2 = 0.575m; a3 = 0.63m; a4 = 1.2m
list1 = StringList( "F0", "mm", a1, a2, a3, a4 ) = "0,575,630,1200"
b1 = 0.0m; b2 = 0.325m; b3 = 0.63m; b4 = 0.2m
list2 = StringList( "F0", "mm", b1, b2, b3, b4 ) = "0,325,630,200"
positions = StrListUnion( StrListSort(list1), StrListSort(list2) ) = "0,200,325,575,630,1200"
StrListJoin
StrListJoin can be used to concatenate two string lists.
list1 = StrList( 1, 2, 3 )
list2 = StrList( 4, 5, 6 )
StrListJoin( list1, list2 ) = "1,2,3,4,5,6"
StrListJoin( list2, list1 ) = "4,5,6,1,2,3"
StrListUnique
Removes all consecutive duplicate elements from a sorted string list.
list = StrList( 1, 2, 3, 3, 7, 8, 8, 9, 10, 10, 10, 11 )
StrListUnique( list ) = "1,2,3,7,8,9,10,11"
StrListMerge
Merges two sorted string lists into a single string list.
list1 = StrList( 1, 3, 7 )
list2 = StrList( 2, 6, 8 )
StrListMerge( list1, list2 ) = "1,2,3,6,7,8"
StrListUnion
Creates a sorted string list consisting of the elements that exist in one or both sorted string lists.
list1 = StrList ( 1, 2, 3, 5, 7, 9 )
list2 = StrList( 2, 4, 5, 6, 8, 9 )
StrListUnion( list1, list2 ) = "1,2,3,4,5,6,7,8,9"
StrListIntersection
Creates a sorted string list from two sorted string lists which consists of the elements that exist in both lists.
list1 = StrList ( 1, 2, 3, 5, 7, 9 )
list2 = StrList( 2, 4, 5, 6, 8, 9 )
StrListIntersection( list1, list2 ) = "2,5,9"
StrListDifference
Creates a sorted string list from two sorted string lists consisting of the elements which exist in the first list but not in the second list.
list1 = StrList ( 1, 2, 3, 5, 7, 9 )
list2 = StrList( 2, 4, 5, 6, 8, 9 )
StrListDifference( list1, list2 ) = "1,3,7"
StrListDifference( list2, list1 ) = "4,6,8"
StrListSymmetricDifference
Creates a sorted string list consisting of the elements which exist in either of two sorted string lists but not both.
list1 = StrList ( 1, 2, 3, 5, 7, 9 )
list2 = StrList( 2, 4, 5, 6, 8, 9 )
StrListSymmetricDifference( list1, list2 ) = "1,3,4,6,7,8"

Security
[TEDDS-5564] Updated embedded Chromium browser (CEF) to address security vulnerabilities
[TEDDS-5558] Updated System.Text.Encodings.Web to 4.7.2
Writing Custom Calculations
[TEDDS-5619] Modified the behavior of the developer commands for creating calculation examples to always save the variables in SI units so that numeric precision issues are avoided when saving US examples using US units.
[TEDDS-5620] Enhanced VerifyEqual so that when the result is different the warning message indicates the percentage difference between the two values.
[TEDDS-5546] Fixed the Data List design application not initialising the "Hide grid" and "Fixed splitter" options correctly which resulted in these options being applied randomly when building a data list.
