Structure Point Sp Column Crack
Jamar Lizarraga
1) i would like the radiuses of the columns to vary according to the shortest distance between the center of the column to the closest of multiple attractor points (or another system to detemine by hand a few different radiuses for the columns)
The first link did help in making a more elegent script, yet it doesn't allow the variation of radius or the deviation of the column from the center of the upper circle that I was looking for...
also- the script it to heavy when I try to put the center points of the columns on a paneling tool "surface domain number", making my computer move to wat slow... is there a mesh alternative for the surface?
1. I managed to change the veronoi grid to a rectangular one, but when i try to put circles on it- it goes crazy- doesn't recognize which center goes to which point on the circles, and creates too many lines.
for point 1, it was just a matter of flatten, data structure is not simple and some changes modify the structures of data. Instead having a list wint "n" elements you get a tree with "n" branches !! So its cures almost everything.
I had a choice for the extraction of points from polygon, it extract by edge or for all the closed polygon. By edge it allows to merge the points of the mesh more easily. I also add some example to change the upper shape of pillars.
In this definition, a series of three points is moved vertically with a random distance and then each point gets projected to the next surface in two random directions. In this case you need a loop, since you have twice as many points after every loop. The resulting lines can be cleaned up with the topologizer plugin.
I'm attempting to parse an XML file. When I point the Input Data tool at XMLFile2, the tool indicates "Invalid Document Structure at Line 1 Column 1". When I point the Input Data tool at XMLFile1 or XMLFile3, the tool indicates no errors. All the files are located on a network drive.
I am looking for a way to obtain and change the rotation of a structural column in Revit. The out of the box column family does not have a rotation parameter, and the rotation seems hard to control in general. We want to rotate columns that have already been modeled to be tangent to a radial grid.
I have noticed that a rotation angle becomes available if the column style is set to slanted rather than vertical. My approach now would be to change all the columns to slanted with one script, run another script that calculates the correct rotation and gives the value to the column, then a third run that returns the columns to being vertical.
Highly recommend against converting to slanted then back again, this will wreak all sorts of havoc in your model not to mention if there is a lot of framing attached to your columns it will take an unacceptably long time.
The setrotation tool also has a bug where significant quantities of instantiated member rotation assignments will actually produce rogue columns. That means dynamo shows the preview in one location but places in the database in a different location!!! You can get around that be running in stages. Step 1 instantiates, step 2 applies rotation.
Thanks for the response.
But I see your column family has cross-section rotation parameter built into it.
I only get this parameter for our beam families.
So I had to use the familyinstance.set rotation node.
I ended up filtering the family instances by the elementID based on the selection.
I have multiple MCLs, and I wanted to create an event structure that was generic and could process any of them the same way. But the problem with that is that I don't know a way to get access to the PtRC method for each one. The only way I know to do it would be to use VI Scripting to create the reference on the fly (not sure if that would even work), but even if that works for me, I don't think it will work with the free LV RunTime Engine (my experience is that you can't use the RTE to execute any VIs that utilize VI Scripting).
You're almost there- just use an explicit rather than implicit method and use that CtrlRef node on the event structure to give you a reference to the control associated with the event. At that point all you need to do is add the MCLBs to the event structure.
Here's what I ended up with...thanks everyone for the suggestions/help...I use the label field of all my controls to index into an array of all the refnums (I scan them all as the first step when my VI executes), and the event structure you see is what executes any time there's a mouse up event on an MCL (I have a separate array of all MCL events)...
Hi. I am trying to create a calculated column step in T&C where I can use the result of a case statement as a subquery. I was thinking that I can either set a temp variable or assign it a name as below. Not sure about syntax. The error I keep getting is the missing keyword. Thanks!
If you're trying to create a calculated column, then you've already named it, so any alias you're trying to explicitly define in the CASE construct could be conflicting... I would remove the "AS Y" phrase.
Well, I'm trying to do a nested case statement. So, instead of writing three different calculated columns and then each calling on the prior as a result, I just want one column if possible. Is it possible/. Maybe case statements aren't the way to go?
Geometry is an abstract type. Geometry values belong to one of its concrete subtypes which represent various kinds and dimensions of geometric shapes. These include the atomic types Point, LineString, LinearRing and Polygon, and the collection types MultiPoint, MultiLineString, MultiPolygon and GeometryCollection. The Simple Features Access - Part 1: Common architecture v1.2.1 adds subtypes for the structures PolyhedralSurface, Triangle and TIN.
Geometry models shapes in the 2-dimensional Cartesian plane. The PolyhedralSurface, Triangle, and TIN types can also represent shapes in 3-dimensional space. The size and location of shapes are specified by their coordinates. Each coordinate has a X and Y ordinate value determining its location in the plane. Shapes are constructed from points or line segments, with points specified by a single coordinate, and line segments by two coordinates.
Coordinates may contain optional Z and M ordinate values. The Z ordinate is often used to represent elevation. The M ordinate contains a measure value, which may represent time or distance. If Z or M values are present in a geometry value, they must be defined for each point in the geometry. If a geometry has Z or M ordinates the coordinate dimension is 3D; if it has both Z and M the coordinate dimension is 4D.
A LineString is a 1-dimensional line formed by a contiguous sequence of line segments. Each line segment is defined by two points, with the end point of one segment forming the start point of the next segment. An OGC-valid LineString has either zero or two or more points, but PostGIS also allows single-point LineStrings. LineStrings may cross themselves (self-intersect). A LineString is closed if the start and end points are the same. A LineString is simple if it does not self-intersect.
CircularString is the basic curve type, similar to a LineString in the linear world. A single arc segment is specified by three points: the start and end points (first and third) and some other point on the arc. To specify a closed circle the start and end points are the same and the middle point is the opposite point on the circle diameter (which is the center of the arc). In a sequence of arcs the end point of the previous arc is the start point of the next arc, just like the segments of a LineString. This means that a CircularString must have an odd number of points greater than 1.
A CompoundCurve is a single continuous curve that may contain both circular arc segments and linear segments. That means that in addition to having well-formed components, the end point of every component (except the last) must be coincident with the start point of the following component.
PostGIS implements the OGC Simple Features model by defining a PostgreSQL data type called geometry. It represents all of the geometry subtypes by using an internal type code (see GeometryType and ST_GeometryType). This allows modelling spatial features as rows of tables defined with a column of type geometry.
The basis for the PostGIS geometry data type is a plane. The shortest path between two points on the plane is a straight line. That means functions on geometries (areas, distances, lengths, intersections, etc) are calculated using straight line vectors and cartesian mathematics. This makes them simpler to implement and faster to execute, but also makes them inaccurate for data on the spheroidal surface of the earth.
The PostGIS geography data type is based on a spherical model. The shortest path between two points on the sphere is a great circle arc. Functions on geographies (areas, distances, lengths, intersections, etc) are calculated using arcs on the sphere. By taking the spheroidal shape of the world into account, the functions provide more accurate results.
You can create a table to store geography data using the CREATE TABLE SQL statement with a column of type geography. The following example creates a table with a geography column storing 2D LineStrings in the WGS84 geodetic coordinate system (SRID 4326):
the spatial type modifier restricts the kind of shapes and dimensions allowed in the column.Values allowed for the spatial type are: POINT, LINESTRING, POLYGON, MULTIPOINT, MULTILINESTRING, MULTIPOLYGON, GEOMETRYCOLLECTION. The geography type does not support curves, TINS, or POLYHEDRALSURFACEs. The modifier supports coordinate dimensionality restrictions by adding suffixes: Z, M and ZM. For example, a modifier of 'LINESTRINGM' only allows linestrings with three dimensions, and treats the third dimension as a measure.Similarly, 'POINTZM' requires four dimensional (XYZM) data.
