I am about to implement an algorithm that takes a point and gives minimal polygon that contains it. (or null, be there no such polygon) Observing the hatch command, one would think there is already functionality that covers this. But I fail to get on its track.
View 2 RepliesIs it possible to create jon between point feature and polygon feature which is not attribute based, but only geometry based.When point is inside polygon can I create automatic join between point and polygon so I can use joined attribute data table.
I know i can create "object data records" links between enclosed text and polyline but i want to do same thing using SDF format points and polygons. Can it be done without converting point feature label to text and polygon to polyline and then creating automatic links and then again converting polylines with object data to SDF format.
I have a database containing more than 5000 parcels. each parcel have its set of points with their labels, and for each parcel I have to generate a drawing. Is there an algorithm for placing point labels inside the polygon of the parcel with minimum overlapping ?

A good method or the algebraic formula for a function to tell me if a point is inside a polygon or block's area?
In Photoshop / Illustrator, when I create a polygon, and rotate it around it's center point it wobbles. When I scribe it inside of a perfect circle, and rotate it around the circle's center point it rotates smoothly. Basically proving that (at least according to these Adobe products) that the center point of a circle is different than the center point of a polygon scribed inside of it.
An image – the dots in the center are the corresponding center points according to Adobe:

This is incorrect according to basic math. Is Adobe aware of this bug?

I am trying to locate a .wdp file with minimal user input. this is what I have so far
;All file saved in this folder
(setq filedir "I://PROJECTS//")
;User will put the following in, but there might be a small description after 915-01. That is why I have a wildcard
(setq filename (strcat "915-01*"))
; string together everything
(setq nextlevel (strcat filedir "JOB " filename "*" "//ACAD"))
;; the final path should look something like this:
I://Projects// JOB 915-01(something here... could be anything or nothing)//ACAD//915-01(something else could be here as well).wdp
;set file extension
(setq fileext ".wdp")
; search files
(setq wdp_file (vl-directory-files nextlevel (strcat filename "*" fileext)))
I am confused on where and when I can use wildcards for searching directories.
I want to create images with minimal file size using .net.

I need to go around buildings, ponds, etc. What is the best way to tackle this? I thought about 16 splines at 330', but as soon as the spline is moved the distance changes.
View 2 Replies View RelatedI need to find a way how to insert a point or a * on the center point of a hole and put it on a different layer. The reason for this is - I am a CAD tech for a welding shop and we cut parts out of steel and we use the dxf file format for our plasma table to cut parts. For example : if i have a 1 inch thick plate and want to put a 3/4'' hole in the plate the hole will be distorted because the hole is smaller than the material thickness. For these situation we can use the plasma table to burn a point or a dot on the center point of the hole. But to do this the point or dot must be on a different layer in the dxf.

Civil 3d 2012..I used 3d orbit, it crashed. My points, point groups and newly updated description keys are gone.I have looked at all my backup files etc, and they do not want to display.

How do i get the 3d poly line to snap to my points so I can Connect them? someone mentioned using a feature line to connect the points but im not sure how or what that would do.

I'm trying to draw a plan of my house in Autocad 2009 but I seem to be endlessly using trim and extend because I can't easily select the points that I want with osnap. Eg. imagine I have a box, and I want to start drawing another box inside it that has each side as 10 units smaller than the corresponding side on the outer box.
Step 1 - I draw a small line from the top left corner of the big box using the endpoint snap, typing in "5" for the length.
Step 2 - I then do the same at right angles to the first line to get me to the starting point of the inner box. This always leaves me with 2 small lines to remember to delete.
Step 3 - Then in order to draw the top line of the inner box I end up drawing to a random length because I can't say "draw until 5 units away from the right hand side of the big box", then I end up trimming it later once I've repeated steps 1,2 and 3 for the next side of the inner box.
I know in my example above I could have scaled the box down or something but that's not what I'm getting at. I really want a way of selecting line start and end points that are a known position away from an existing point.
I have a database of points I am trying to import, and the point data for each point includes a hyperlink. I've created a set of custom User-Defined Property Classifications for all the data types in the point database, and I've created a point file format to use to import the points.
It's a database of existing curb ramps, the data includes things like widths, slopes, some text, and a hyperlink to the Google Streetview at each ramp. I've created a custom point label that will show the data I need to see at each ramp.
All goes great except that the import fails because of the hyperlinks. I've tested it by removing the hyperlinks from a small test portion of the data set, and the test points are then successfully imported. I suppose I can delete the hyperlinks from the entire database, but if there is a way to include the hyperlinks in the point import I would prefer that.

how to match up certain points. I have imported 2 point clouds and have tried to use the 'align' tool to specify three points from the source object (cloud) and three points from the destination object (cloud). When doing this, it does not properly align them. The point cloud makes it difficult to select the exact point I would like to align, since there may not be a point at that exact location, but close to it. Does AutoCAD require the points in alignment to match up perfectly or is it capable of doing a best fit?
Also, is AutoCAD capable of creating a solid 3D piece from the point cloud? I would like to take all of my points and make a smooth object.
How to set a default point style for point groups? Whenever I import survey points, I always put them into their own point group, so I can display each day's worth of survey data differently. For some reason, the point style always defaults to a certain style (our control point symbol). I'd like it to default to Basic, so I don't have to change this every time. Is it a template drawing setting somewhere?

I've MAP 3D 2013 64 bit (French version) with SP1.
When I launch command to "Convert polyline to polygon" (_MapPolylineToPolygon), I've message on command line "Select objetcs", I can convert to polygon =>OK
If I launched this command a second time, I've no possibility to select object, I come back to command line.I quit MAP, then launch MAP, and I can use this command only 1 time.
This problem appears after SP1 was applied.
I have a series of polylines with a global width of 5m which I want to export to a polygon shapefile to represent in GIS. I realised if I create a shapefile of the polylines and then create a buffer of 2.5m on either side I can create my desired polygon. My question is how do I export this polygon to a shapefile. I have tried bulk copy but this just seems to revert the buffer back to a polyline shapefile .
