I have polylines that when selected, under properties it lists Object Data for the selected polyline. There are like 10 categories. This drawing is actually creeks in a county and they have object data connected to them where some are "a" some are "b" classification and I want to select all of the "a" polylines and put on a diffrent layer.
View 1 RepliesI've been working on a custom polyline object, and I've got it functioning!!Having said that, I plan to run its creation around picking a point for bounary selection.
(Other than trying to step through every vertecies) is there a technique I can thow the polyline data from a traceboundary result into my custom object? I've been trying to add the polyline from traceboundary to my object BEFORE it's added to the transaction by the way...I assume that's right, since I want to put it's data in my custom object then add my custom object to the transaction instead.
We need to take polylines from AutoCAD Map 3D to 3ds Max and rename each polyline to have a name of something like "Building Number-Room Number", both of which are defined in our properties for each polyline. Because none of this data is kept on import to Max, we need to do this all in Map 3D, which we are not experienced with. Is there a way to do this, and if so what? We are importing the .dwg files in Max with polylines as splines.

View 9 Replies View RelatedRunning a Query that inserts a block with attributes filled with text derived from a file that has a large set of polylines with object data (text)? Is it easier just to insert this object data as text with a query. Or can I place this object data (text) into a block that inserts?
Example:
- You have land locations defined within the object data assigned to a set of closed polylines. (Large subdivision)
- Field name for object data on each closed polyline is "LAND_LOC"
- Now, I'd like to label these locations with a block that inserts to a central point within the closed polyline.
- Block Attributes with "get" the information from the polyline / object data and place this value in the block attribute.
- I have 1 drawing file that has closed polylines with object data assigned to them.
- What is the best method for this? I'd like a block with attributes to insert and pull the object data / field and place it into the block with a defined attribute, that is central to each of the closed polylines. (LAND_LOC)

View 1 Replies View RelatedIs there a way to define object data to a polygon or a poly line in C3d? I imported a shape file and saw that in the properties dialog box the object data of the polygons is displayed. I would like to define create new polygons and define certain atrributes to it before exporting it as a shape file. This would would eliminate the need to use a GIS program to define the attributes of the polygons.

I 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.
We have a perenial problem with our old GIS software where files corrupt and drawing objects are lost.
There are few export options available, but export to shape is one of them. This means that I can export a damaged file and then import it into CAD with the layers intact and the tagged numbers (similar to object data or a block attribute in CAD) imported as object data. In order to make a new uncorrupted version for the GIS program.
Is there a way to select objects by object data?
If a file is corrupted, the only real way to repair it at the moment is to go back to the original cad drawing and reimport and then retag every single tagged attribute on what can be thousands of drawing objects, and by then we may no longer have the handdrawn data to even do that.
The next workaround is if I creat new dwgs from the cad drawing, Each one containing the objects with the same object data, and each saved with a file name that matches that object data, and then reimport into the GIS. (it can use the filename as a tag). This creates a new GIS file with the surviving information that should not lose any more data and we may be able to patch the 'holes' afterwards.
The problem is selecting all the polylines in the cad drawing that have that same tagged number in the object data. Select similar just goes on object type and layer. This would be easier if I could select by object data and get everything with the same tag in one go.
A way to batch create the new dwgs from that selected data would be nice too.

Is there a command to combine two 3d polylines into a single polyline? Either combine, take the mean between the two lines, or draw a third line at the mid distance between the two original lines?
The lines are created (in a .dxf) by a GPS unit in the field, and represent tracks needing to be mapped. Typically we would drive out a track and then drive back on the same track; this gives me two 3d polylines. Because of GPS errors it better practice to log the roads/ tracks twice. The lines can have from 2000 to 10000 vertices, so manually drawing is not an option.
I have two polylines. Segments of one polyline are directly on top of segments of the other polyline. When I grab one of the polylines to stretch the vertices, it grabs the vertices of the polyline underneath.

My selection set consists of dbpoints that exists on my drawing and they are more or less in line

The only idea I have is:
from start point i calculate the distance to each point3d from collection and based on the results i sort the point3d collection based on distances.
Existing polyline set to a width of 6. Want to fillet this to a non-polyline with a width of zero.
Currently the two lines will join to create a connected polyline but the original widths are maintained (6 and 0).
I am looking for the system variable where the non-polyline becomes joined and the global width for the new segment matches the first polyline.
I have an irregular shaped polyline in civil 3d that needs to be 31.5 acres. It is currently 32.8 acres. Without manually rescaling this polyline over and over again in order to achieve a polyline that represents 31.5 acres, can Civil 3D automatically draw the polyline to represent 31.5 acres for me?

I use this technique quite often in Excel. One cell in a table can have various values: A, B, C, or D. While another cell can have a different set of values to choose from: BLUE, RED, ORANGE, or PURPLE. The user can pull down an arrow (similar to a dynamic block) and choose from a set list of values.

How to create such type of drawings in autocad civil 3d.
I would like an VB application that from within autocad can open an excel file,from there select 2 columns containing x,y co-ordinates. Which when selected will draw a polyline in the acad drawing.

I'm trying to select all Text-based items (Text,Mtext and Attribute References) in a drawing to check to see if they match a pattern in a regular expression. Although i have a block with an attribute in the drawing and the selection filter consisting of

DxfCode.Start "ATTRIB"
DxfCode.Start "TEXT"
DxfCode.Start "MTEXT"
DxfCode.Operator, "OR>"
It isn't picking up the attribute Reference in the block.
Is there a workaround using the Editor.SelectAll method and not having to programmatically check each block's attributes? I'm using AutoCAD 2009.
In 2007, I was able to select multiple polylines before typeing in PEDIT. When I was done with the command, I could then type in PEDIT and L for last and it would select the multiple polylines I had first selected. We just got 2012, and when I do L now it just selects one line. Can I change this?

View 5 Replies View RelatedI need to have symbolized linestyles on a number of 3D polylines in mapping data.We normally would simply explode the 3D poly's, and our linestyles display fine.
The linestyles also display fine if we change the 3D polylines to polylines.HOWEVER, with the current dataset we have very high point density on our 3D polylines, and we need to preserve the elevation attributes of the lines.
If we explode the lines we end up with so many tiny segments that they will not display the linestyles - changing the linetype scale eventually will show the style, but at far too small a size to be relevant.
We also, in most of the layers, are not able to change the 3D polylines to polylines - we must preserve the 3D attributes of the lines.So the problem is that we can't explode the 3D polylines, and we can't flatten them either, but we want the linestyles to display.We are using Map3D primarily, but can access C3D if a solution is available there.
The precise scenario is for instance a line which is a top of embankment, but which has points at around 30cm intervals, over a line length of 206m. This particular dataset has several hundred lines like this, and the linestyle we are trying to display is a simple set of repeating ticks off one side of the line.
We are experimenting with weeding the points, but the shape of the lines is being considerably downgraded by this process.at this point we are most likely going to have to present this data without linestyles for these features - not our first choice.
There is a AutoLISP for extract START and END coordinates in X, Y, and Z planes, and extract length of Polylines and Arcs.?
View 7 Replies View RelatedI design all of the architectural metal used on most project homes being built in Sydney at the moment.
I draw up balustrade and screening etc.
Basically what I have is a huge collection of complex dynamic blocks that I insert into my drawings, I then change all the variables to suit.
These drawings are then dimensioned, and a parts list manually written out based on the lengths etc of each type of material.
All of these drawings are exact reproductions of what is produced on the factory floor, so it is quite easy to identify the parts, but rather painfull to manually write out a cutting list.
I'd like to add attributes and/or fields for material type and length to each of these dynamic blocks, which update as the blocks are manipulated to the required sizes.
where I get stuck is that there are multiple drawing methods used to create these blocks, and I cannot seem to figure out exactly what I should be naming, and assigning length fields too, or even how to extract or what to extract!
When I extract the data, I get a mess of conflicting and confusing information that is impossible to sort correctly, as I can use the dynamic parameter field for some, but not others, and on others it is a simple line, but on others again they are polylines and the length is useless to me.
I have tried to creat a block with an attribute for each and every individual part, but when I combine these into a complex part and try to assign dynamic parameters as a single dynamic block, the previously blocked and named parts wont behave correctly.
Im not sure if im making much sense here, but in my mind it all seems simple enough, I just cant get it to actually work with my exsiting blocks...
All im really after is a simple BOM, for example, I have a dynamic block with the Style code A0-1, when this is inserted I change 3 different lengths depending on the job. This style code is made up of several components such as a 40 mm square post (coded 40SQ), an 80 sq baseplate (coded PF2) and a 50 x 25 mm handrail (coded HR5025).
I need to extract a length for the 40 sq post, a length for the 50 X 25 handrail and an item count for the baseplate.
There may be 25 of these in a drawing, all at different sizes.
The dynamic block works perfectly for drafting, but not so well for data extraction.
There are over 1100 of these dynamic blocks, created over the last 2 years, and the only missing piece in the drafting puzzle is the extracted cut-list to save a large amount of time, and I just cant get it working.
Is there a methodology I need to learn here? will I need to re-create these blocks to allow for extraction?
I have explained to my boss the theory behind all of this and he is keen for some working examples that the monkeys on the shop floor can read and understand, and Im stuck creating an extraction template that can work, even if just for proof of concept that I can refine over the next few months.
I know ACAD can do this, I know my brain has all the data, I'm just not getting the ACAD>BRAIN interface working here.

View 1 Replies View RelatedI am in case to model a stormwater network contain ditches with irregular sections, open channels and closed pipes in SSA. I do not have access to IDF curves for the Project area. We got a weather station in site which is giving us continuous data from last 3 months till now. At this stage we just decided to use certain Rainfall intensity (mm/hr).
We got some check points to check the turbidity. What I need to know after analyse is i.e what is the flow at these points at 6:00 pm if we experience the rainfall from 3:00 pm to 4:00 pm with 20 mm/hr rainfall intensity.
So my concerns are with these available basic data, which method is suitable? and as long as we approach more valued data from in site weather station then which method will be the best. If i want to input time of concentration manually for each subbasin then how can i input TC of pipes or channels in SSA? URL....
where MATT said: "SSA does not calculate the Standard-Step method. The Rational Methods (including modified, and DeKalb) all compute the runoff to the inlet or junction. As soon as runoff enters the system, continuity and momentum calculations take over. SInce you are using Steady State Qin = Qout, so no routing occurs on pipes."
how do i understand the flow in certain points i.e 2 hrs after the rainfall is finished if I can not define TC for pipes or channels?
