AutoCad :: Reducing Number Of Points That Are Too Dense?
Jul 10, 2008
I have a problem reducing the number of points that are to dense. they are so close together they basically form a line. problem is that there are about 5000 points at the line were I want to be 50 of them. deleting them manually would take forever...Is there a command that can reduce no. of points at one area?
I have a line drawing from a draftsman. It was imported from some other program, but I'm not sure which. However, this has cropped up many times over the years on my drawings as well as others. It just is typically quickly remedied with a workaround.
The hatch spacing too dense issue requiring me to break up the area: this problem will occur on equally sized areas at the same zoom factor at which I just hatched an adjacent area. I have changed the "MaxHatch" variable environment from stock at 10k, to 100k, then to 1,000k; yet the problem persists. I don't have a particularly fast machine so by that point I decided there was no need to max the variable at 10,000k. There are no z variables in the drawing though it appears, almost randomly, to have plines or lines along the same length of wall.
The second issue is the closed boundary. This occurs on lines that are connected at all corners, even when I stretch and reconnect a line, though that is a very time consuming method. When I increase the hgaptol variable it will hatch bizzarre areas that have no relation to what I am attempting to hatch. This is also occuring even inside a REC that I created just prior to hatching due to error on the original layout. I have to hatch an object rather than select an internal point. It has become so obnoxious in this drawing that I decided to post with these questions.
I am trying to set several hundred points along polyline verticies with the point number starting at 5000. There are no other points in my drawing, yet everytime I start the process, it begins at 1. I have set 5000 at my Next Point Number under Point Identity in the Create Points toolbar. I have also verified that the 'Save Command Settings" is set to yes under the 'Commands-Create Points'. We cannot get this to behave as desired.
I have a point cloud with 161 million points in it. This is basically fine and works well but I need to create equally high resolution surfaces from certain regions of the point cloud. No matter what size I choose my export shape, it will only create a surface from a ridiculously small 750,000 odd points, a 'feature' which has been documented on these forums before. I have POINTCLOUDDENSITY set to 100.
My question is, how can I build a surface from this high resolution point cloud data that has more than 750,000 odd points?
I'm thinking about mosaic'ing - ie. making several smaller surfaces over the required area and pasting them together.
In AutoCAD leader settings you can set the number of point so the leader looks standard. I am searching for this in inventor and am coming up empty. I have seen other engineering drawings where I can tell that the generated data in the balloon was entered from the parts column in the B.O.M. But instead of part numbers, I have seen text. and I have mine set up to generate the Balloons that way but I do not like the leader type it is giving me. The attachment is what my leaders are looking like in inventor.
Any way to reduce the number of vertex points in a polyline or 3d polyline and retain the basic shape but without having to redraw over the top it?
Ideally, I would like any adjacent segments which are in the same direction as each other to become one segment.
In my image you can see the number of points it has, the majority of which are not necessary for my needs (it was imported from a client's drawing). My desired linetype will also not show because of this.
A work mate here at sometime or another clicked on the "always perform my current choice" check box when the "Hatch - Large, Dense Hatch Patterns" dialogue box appeared.
Question is, is there anyway to reset this so the dialogue box comes back up?
Question 1.In C3D 2013 is there a ceiling to the number of points allowable in a C3D surface? Is it 1.5 million?
Question 2. In C3D 2013, when creating a surface from Point Cloud data is there a maximum point count based on the answer to question 1 - or is a different point count limit applied?
How to change the number of decimal places of the elevation of points?
as the points are labeled with their elevations, I couldn’t find how the number of the decimal places of the elevation be chosen. In this case, I wanted to let the number of the decimal places to be zero.
How to set the number of the decimal places to be zero or 1, for example? how to sepcify it height (size)?
I have a point cloud dwg. Is there a way to increase the number of points displayed? The properties of the cloud say there is 14,000,000, but it only displays 34,000. Is there a way to increase the 34,000 number? See Image.
I've got two trajectories from the bottom of two tires and I want to create a road surface, an object whose shape will match the trajectories, thereby creating a perfect shadow catcher.
The trajectories are virtually identical in shape and number of points because the two point helpers that created them were wired together. I've converted them into splines and messed with the loft tool, with not so good results. I ended up brute forcing the shape of the object into some kind of shape but I think there has to be a good, dependable way to do this in a program like max.
How to “synchronize” the ‘layout number” with “sheet number”?
As in most cases, the arrangements of “lay outs” reflects the way they are regularly printed, then how could we renumbering the sheets such that the first lay out takes number 1, the second lay out takes number 2,…and so forth.
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.....
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.
I 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.
I 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.
I 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;
Let 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.
Is there no way of reducing the time?. I understand that this process involves solving of differential equations for reflection of light from various materials in the building etc. Can it not be done through Autolisp instead of going through .NET languages. Common Lisp is also a powerful OOP language. If Alisp cannot do it can Autodesk implement CL and cut short the time?.
I have a 3D model that consists of a large number of "small" objects that i created earlier in separate files. The problem is that now my model is 50Mb and I am having trouble working with it. Is there a way of reducing size, or is there any other solution that would not change the geometry of my model?

i have produced a drawing and have copped and pasted quite a few photograhs on it showing details etc. however bnow my drawing has a very large file size. i have purged drawing, it is the photographs
I have just produced .dxf files from .shp files using Surpac. The problem is that the final .dxf's are that huge in terms of memory that is really dificult to open the .dxf with any version of AutoCAD
