how to get the points of a region using c#. ?
We have irregular shaped regions (and meshes) that we are trying to map for duplication. I've seen the code that gets the mass properties but cant figure out how to expand that down to the individual points/coordinates that make up the border of the region/meshes.
How to go about creating a surface, region or 3D object using non-coplanar points? I'm drawing a few different 3D models for an artist friend of mine to use in her proposal on a local public art project.
However for this version I am bottlenecking on how to create these regions. I have vertical(ish) beams of varying height twisting in different directions with sheets of alternating metals welded in-between, the bottoms line up straight with the tops following an S curve but with the twisting geometry the top two endpoints for each will always be in separate planes.

I had to create a boundary map and place points to all corners. How to export these newly created points back into my data collector (Ranger) and also I'm trying to figure out how to print out a points list.
I stumbled on to this thread but I guessing that it's a different CAD year because my modify tab doesn't look like this. URL.....
I have a large surface (over 1.5 million points and 20 000hectares)
I need to get a point file .csv from the TIN to be able to use it in another program.
-so i've extracted the points from my surface, but they are Autocad points.
-next step is to convert them to civil 3d points.
-I can not select them all when converting them or my computer crashes.
-so i select about 25 000 at a time, the converting takes roughly 10 minutes.
and i have over 1.5 million points to do.
how can i speed this up.
will more ram useful?
there is a way to convert land desktop aecc points to cogo points and use the full description?
I do not have access to the ldt files nor to the Descriprion keys file. It would be nice if there was an option to preserve full descriptions when converting (that would be just too simple).
I have recieved a file with many points and would like to convert them into COGO points in Civil 3D. The problem is; I would like to keep the hole ID's as I convert, I've made a few conversions and lose the hole ID every time (not showing in Name or Description). Is there a seting I am missing to keep these? My aim to to organize the COGO points in different point groups.
View 3 Replies View RelatedI have a couple points that were part of an import event (data from a previous project) which I want to assign as control points for an incoming traverse, is there any way to assign those as control points? I can't seem to find a way to do that other than perhaps re-importing the specific points as control points and overwriting the existing ones.
View 2 Replies View RelatedI have a project that was started by leaving all the survey data inside the "All Points" group. So, I'm concerned that when I enter my as built survey points, that even if I put them into their own group, that the original surface will still look at them and just rebuild to my asbuilt data, effectively cancel out the purpose of the asbuilt survey. Will this happen?
I want to take the original points and put them into a group of their own, but I don't know if that will affect anything or not? I have several wetlands already designed on that surface with volume calcs already done too.
What should I do?

View 8 Replies View RelatedI have two locations marked by steel stakes on my land that are also shown on a CAD drawing. The CAD drawing is two dimensional; however, contours are shown. I have physically measured distances between these two known points and numerous other locations that I wish to plot on the CAD drawing. I could always print the CAD drawing to scale and plot the new points on the CAD printout by using the two known locations, a compass to draw arcs and locating the new points by where the arcs intersect. I am sure there is a much more efficient way to plot these new points within the CAD program itself. I have just started to use CAD;
View 1 Replies View RelatedLet me make my question clearer by considering an example as follows, Assume I have points A, B, C and D in a map. Is there any command that can list the distance between any two points out of all points? e.g. distance of A-B, A-C, A-D, B-C, B-D, C-D.

Here is my file, if you'd like to take a look (the outer portion is my region and I want to subtract everything that's inside it)
Is there a command or a procedure to cut a drawing portion and export to image format?

there is a SliceSolid to solids,but not to region objects,
I need to find center of Region (refer to as Centroid in MassProperties of acad, also known as Centre of gravity if 'element' mass is unique). After few days of googling, searchin i this forum... I still can not figure it out how to get centroid point from Region in VB.NET. For Solid3D is easy while it exposes this property, but Region does not reveal any properties except Area.

View 2 Replies View RelatedI am having one region entity which is not getting exploded.
This region is resultant of solid editing (bolean opearions) on some regions. When I use explode() function to explode this region programatically it returns status as 'eNotApplicable'. And if I try to explode this region manually using EXPLODE command in AutoCAD 2010 it gives message as 'Cannot explode REGION'.
I am not getting why this is causing problem in 2010 only. It is working fine in other AutoCAD versions.
Well ive searched and i cant find one. this as typing REGION repeatedly is annoying
View 6 Replies View RelatedI have the need to curve a region, then extrude it, is this possible?
The region is a flat view of a plasma cut plate with lots of holes/shapes that then gets rolled, doing it the way I describe would exactly re-produce in cad how the finished physical product comes out.
I am starting up my class again using AutoCAD Civil 2011. I want to extrude a circle or just a closed pline to a solid. I have done this many times before, but now it is not extruding to a solid, just a "Surface Extrusion". My commands are C:circle; C:region; (shows as filled circle and confirms it is a region); and finally C: extrude ; when I extrude it it is not a solid but rather a hollow "Surface Extrusion". Is it a function of 2011 and something I have turned on?

I've changed the resolution to 1920x1080 and it seems like autocad rendering all the background+the model to this resolution, so the final result is a lot of background and a model that you cant see the details. the file should be a jpeg or other common picture format but in high resolution.the picture attached is what i got

I created a square and make it as a region. I just realize that they are consist of two kind of overlapping objects.
One is four lines that formed a square and another is the formed square region.
How do I switch the mode back to the AutoCAD classis, which when I create a region, then there only available one object, that is, the formed region.
I want to have a closed region that can display the area of the region (I want to see it on the screen without having to click on the area and look in the properties). Is this possible?
I want the closed region to be dynamic i.e. when I change the area of the region the displayed area should automatically change. Is this possible?
Even better would be if autocad could give the area a id and in a table that can be exported to excel reports the area of the region. Then if I have many regions autocad give every region a new id and all the id:s and areas are reported in the same table.
The routine basically checks for overlapping layers - it does this by copying a reference polygon to a region and doing a series of subtractions to work out how much (if any) of the polygon overlaps another one.
The script works perfectly if the reference polygon is contained completely within another (if it is smaller), or if the reference polygon overlaps the other. HOWEVER, if the polygons have vertices which touch more than once (eg they are the same shape, or share a common series of vertices) then when I run the getboundingbox command, the arrays minExt and maxExt both return 0,0,0. Is this a limitation with the getboundingbox command.
I need to divide a big region on lines intersections. imagine that you create a region around a chess table and break the region so you get each square as a new region.
I can't use array because the sub-regions aren't regular. I need this divided regions to export a DXF file to a Finite elements program.
I,m running 2012 LT. Whenever I go to select a point on a region or move an object to a regions vicinity the computer hangs. Exploding the region relieves the problem. Large drawings or anything else don't seem to cause a problem.
View 1 Replies View RelatedI'm trying to calculate the principal moments (and section modulus) of a slection of closed polylines.
On this blog, I read that there are some new classes and functions in the AutoCad 2014 objectARX that can do this.
The one that interests me the most is 'RegionAreaProperties.PrincipalMoments Property'.
However with my limited programming skills, I can't get it to work in vb.net.
I thought is was just a property of a region, but something like 'myregion.RegionAreaProperties.PrincipalMoments' does not work.
With the code I already have I use a selectionfilter to select multiple closed polylines. I can convert these to regions if nescesary. But what is the next step? I can't find any samples of it. Not even in the Autodesk Developer's Guide.
