I always get the message after I make a closed boundary polygon, and I know it's a closed boundary, but I know how to fix it. It just bugs me sometimes when the message pops up when I add it as a boundary under the definition of a surface.
View 2 RepliesI am trying to find a command that will hatch the inner edge of a complex closed poly line, rather than hatch the entire area inside the poly line.
When I have simple shapes such as a rectangle I create a smaller rectangle inside the first that is 1' (or whatever I want my hatched area to be) smaller on all sides than the first rectangle. I hatch by selecting the two rectangles; I change the "Associative" hatch property to "No" and then delete the inner rectangle.
My problem now is that I have a complex closed poly line that I would like to hatch the inner perimeter with a set thickness, say 1 foot. Is there an easy way to hatch a inner boundary of a closed poly line or to recreate a scaled down copy of the poly line that is a set distance smaller all around. I hope I have conveyed the question clearly enough.
is there an option or a lisp routine to create a 3d boundary from closed 3d polylines?

View 3 Replies View RelatedI am working on a complex industrial site. And I would like a constant grade of 3.00% from my road intersections to the edge of curves. I know if I used a corridor, I'd be able to tell the grading to project ot the edge of the road/curve.
I'm just wondering if I can tell a grading object to project to a polyline or feature line along a intersection curve? There are many reasons as to why I'm not using corridors for this project, but I don't want to get into that.
I have used PEDIT to join multiple polylines, which now appear as polylines. But when I use QSELECT to show all open (non-closed) section, one polyline still shows up as open.
I've attached the file I'm working on. The polyline in question is the green outline on the object on the right.
I've read 2013 is going to include line labeling capabilities by selecting 2 points rather than selecting linework. Is there going to be a way to label an area without creating a closed polyline or parcel, where it works the way a hatch works. So if I selecting in the middle of multiple individual intersecting lines, it labels the area.
View 9 Replies View RelatedI can do this in AutoCAD Map but I have my doubts. I will explain in ESRI GIS terms (this is what I am familiar with) and I hope you can tell me if I can do this in AutoCAD Map. In ESRI ArcMap I can select a line and I can hit a Select by Location button. In this window I can select all of the objects that intersect my selected line. Then I can delete them or export them etc.
In AutoCAD Map I have a polyline selected. It is my road centerline. I want to be able to select all of the other polylines that intersect my selected polyline. Is there a way to do this? I need to erase those polylines. Usually I will pan to each of them and select them individually. It just seems to take a lot of time. My AutoCAD co-worker said I could use a fence and draw the fence through my polylines. It seemed to work ok but I accidently deleted extra things that I needed. So I'm back to manually selecting each one by one unless you know a different way.
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 need to know if there is any way to control the points in the point cloud.
1. either only import the point cloud in a polyline area i specify
2. add all the points within a boundary not limited to the pointclouddensity = 100, freaking default is 15 almost cost my job today. extremely stressed out right now.
i am talking about extreme lidar surveys. 1km 1km LAS/0.5m contours/xyz files times 355 of them. covers a 2km wide corridor. but i only need 100m wide after i define the road alignment. no need to have all the extra points.
right now i densify the heck out of it and end up like 5-12m points. decent but not good enough because the geotech is bitching about that accuracy is not good for some feasibility study. or is there any software i can do this besides civil 3d.
what i want can also do is automate the 'add points to surface" under point cloud and have the software do multiple boundaries without having me baby it over the night. right now every click is 5 minutes and adds like 400k to 1 million points. Civil 3D 2012

Is there a command or lisp that will allow you to select a closed polyline and trim everything outside of it even if the items are blocks that aren’t exploded?
I’ve tried EXTRIM but that fails on blocks.
When I try to extrude this closed polyline (yes it is closed) I get the message "Cannot sweep or extrude a self-intersecting curve." I do this sort of extrusion all the time (closed polylines with various geometry) and usually have no trouble.
View 9 Replies View RelatedI've been using the admittedly pieced together code in order to insert border blocks around a closed polyline. Yhe problem I'm having is that when the Block angle is say "zero" the block is inserted the same way both on top and below the polyline. Since the blocks surround the polyline the blocks on the downside should have an additional 180 degree rotation. How to deduct that the portion of the polyline is in a certain quadrant and adjust the insertion angle as necc? I 'm not sure thats even the best approach.
Dim pso As PromptStringOptions = New PromptStringOptions("Enter name of block to create reference: ")
Dim pr As PromptResult = myEd.GetString(pso)

Is there a way to select objects within a closed polyline? I thought there was but I can't remember how to do it.
View 2 Replies View RelatedPresently the "AREA" of a closed polyline is in "sq-in" first, THEN "sq ft".
For everything I do, and likely others, I need sq ft - without having to waste time and roll my cursor over the results.
Is there ANY way to change this default to have sq ft FIRST!??
I was wondering if there is a settings for the displayed values in a polyline's properties. Such as area. Normally it will display square feet but I would like for it to also display acres. I know it a simple conversion, but over the course of a year or more it could save me alot of time.
View 2 Replies View RelatedI need a lisp that can remove all objects (lines, polylines, blocks etc.) outside of a polyline. polyline is closed and shape is variable, so not rectangle.
View 3 Replies View RelatedI cant do booleans with polylines, for that I need to convert them to regions which I dislike because I lose edit vertex capabilities right? Also, from a region, how can I convert a region to a closed polyline in one go.
View 2 Replies View RelatedI can draw a closed polyline representing a closed area.
I can then toggle its 'closed' property and it seems to make no difference. area is same, I can extrude or create regions, I can hatch in either case.
in which specific situations we should bother about whether a polyline is closed or not?
I want to find the cardinal points ( N, S, E, W) of each face of a closed polyline, how?

I'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.
I have linked my drawing to a database with text inside a closed polyline. Is there a way to have the area of the closed polyline stored in the database as a live area.
View 8 Replies View RelatedI drew a very complicated 2-D plot this afternoon. The most majority of the plot is composed of different straight lines, arcs. Then I used the polyline function to join them together to form a closed single polyline (Modify->object->polyline).
Later on I want to change something in part of the polyline. Then I used the 'pedit' again, I chose 'open'. But the whole polyline won't break into its original segments. I tried through all the menus, just cannot find the right tool for this purpose.
Does it mean I have to start over from scratch to redraw the whole plot?
I am a landscape architect, and am trying to use bushy linetypes to delineate blobs of mass plantings. I created my custom line types, and tweaked them to the point where they look the way i want, but whenever i have a curve the line type faces in not outside the closed polyline. all of my shapes are closed poly lines, and i need the linetype to face out other wise it looks weird. I am attaching a picture the strait line to the right is the way that it is supposed to look, but in the circle you can see how the points are all facing in to the middle of the circle? reversing the direction dose nothing, and using a or u in the place of r in the linetype shape code doesn't work either below is the line types code and image.

I'm trying to model a 3d leadscrew. How can I extrude a 2d closed polyline in a straight line while at the same time twisting it (360° twist for every 1.5" along the path). I've tried loft, sweep, extrude all using the helix as a path. When I can get a result, it ends up being a corkscrew.
View 9 Replies View RelatedI have been using AutoCAD to create product designs (baby bottles) for the last three years. I am normally drawing lines, arcs and splines to create the shape, then I use PEDIT to create a closed polyline and REVOLVE to create a SOLID 3D object from that shape.
Couple days ago, AutoCAD is not longer creating 3D solids when I use REVOLVE as usual (even using older files and/or the same shapes or polylines that I have used before to create 3D solids). The result of REVOLVE is "SURFACE (REVOLVE)" (I got that from properties). But, the most uncommon thing is that AutoCAD is revolving fine one or two times per day after many many tries. (normally I am closing and opening files and trying to revolve some stuff many times, using the same process and suddenly it revolves the sahpe as a 3D solid)
I attached a picture showing two objects created using the same group of lines, splines and acrs. One is a solid 3d object and the other one is a surface (revolve) as result of using REVOLVE command. WHY????
