Extraction of subtables
The basic command to choose elements inside a table is dtgrep
Selecting sets of tags
In order to create a subtable with a predefined set of tags, use the flagtags:
tr = dtgrep(t,'tags',[5,9,11:15]);
would explore the table t and create the output table tr, including only the tags 5,9, 11:15.
Excluding sets of tags
In order to exclude a set of tags, use the flagexclude:
tr = dtgrep(t,'exclude',[5,9,11:15]);
would explore the table t and create the output table tr, excluding any rows with tags 5,9, 11:15.
Selecting subtables by property
The flag tr (for table restriction) allows operating restrictions on a table.
= By property name
If you know the shortname of the property, you can use directly:
>> tRestricted = dtgrep(t,'tr','0.3<cc<0.5');
operator 0.3<cc<0.5 (#1) 100 before, 16 after
= By column number
>> tRestricted= dtgrep(t,'tr','0.3<&10<0.5');
operator 0.3<cc<0.5 (#1) 100 before, 16 after
Geometrical operations on tables
Rigid body operations can be applied onto tables with dynamo_rigid_apply.
