AutoCAD 2013 :: Line Type Generation With 2D Polylines?
Apr 17, 2013
I'm woring with 2D polylines as exported from another piece of software. The problem I have is that the LTGeneration resets to disabled evertime a polyline is edited, ie broken or trimmed. Plinegen is set to 1 as the system variable, but as far as I can tell every time a line is broken etc it creates a new entity that doesn't inherit the ltgen properties of the previous line or the system variables. I know i can convert to polylines, but is there a better way?

I have several .dwg files which I attach using XREF so that I can ensure I have the latest versions combined.
The problem is that the line types do not show up correctly. After looking up on google I have found that this is a problem due to it being a 3d model rather than it being flat.
I managed to half solve the issue by inserting each drawing into one, then exploding the whole image. Then changing the scale in the bottom right to around 1:200 to make the line types visible.
My problem is this ends up being a lot of work as the separate drawings can be updated daily. Is it possible to have all the drawings Xref'd in and to be able to have the scale changed to be able to read the line types? I tried to save the XREF setup as a template, then just bind all the drawings into one, explode and change the scale. But for some reason this doesnt work for me. I end up with just solid lines, rather than line types. I don't the drawings are made up of several lines, all of different length. (This I have been told is why the scales do not appear correctly)
I have been shown one method to work around this, which is to open the Xref drawings, explode them, then take each section of line and manually change each scale to the biggest that shows up.

I have a piece of code that needs closed polylines.
I use the following selectionfilter to filter the selection so I can only select closed polylines:
Dim sf As New SelectionFilter(New TypedValue() {New TypedValue(0, "LWPOLYLINE"), New TypedValue(70, 1)})
Today I noticed that in some drawings this filter won't select all the closed polylines for me.
After some experimenting I found the 'linetype generation' property of the polylines to be the problem. If this is enabled the above filter will not let me select a closed polyline. If I disable it, there is no problem.
How can I make my code for selecting closed polylines more robust? Is there a 'TypedValue' for closed polylines with the linetype generation enabled?

I need to represent some lines, in model space, that alternate in color, yellow/red, that are "scalable" with respect to different scale view ports in paperspace.
my initial idea was to use two lines, each in which the dash and space between were the same distance, then just offset the yellow/red lines enough for each to fill the others gaps. But, wondering if it was possible to represent that in a single linetype?

I have a problem with line type scale for hidden line it appears different line type scale in another drawing, al though the setting for line type scale & Global scale factor is same for both the drawings. Is there any other setting for the line type.

I have tried to load a custom line type from Autocad 2013 to Inventor 2013, through Edit Laver-->Line type -->Other --> Load, but it doesn't appear in the drop-down list. I have read that previous Inventor releases coudn't work with autocad custom or complex line types. Is it still like that?

Why when I choose a new layer (which happens to have a different colour association) the colour of the new drawn line stays the same?

I understand there is some setting you type in the command line to solve this problem but I am unable to find what that is.

Is there anyway to line up the dashes of overlapping polylines so that when I have 2 or more dashed polylines on top of each other the polyline will still looks dashed. Because at the moment the dashes don't line up and the polyline appears as a solid line where they overlap.

I have used color to determine line widths. The plotter set-up recognizes color and assigns the appropriate line width. My new company is determining line width by using polylines. Am I behind the times? Or, is this a better way. Willing to change.

I created some new custom line types using express tool featute in autocad and I saved it with a .lin extension. It is only available in that drawing itself. How I canget those line type in all my new drawings.
I tired to edit the default linetype file even it doesnot appear in the linetype manger windo.

polylines in my current drawing have started to come out with a very fat line width. It doesnt matter what layer its on, even though previously they were drawn 'properly' i.e the thin line width that shows when you have show/hide lineweight on 'hide'. This doesnt happen on any other drawing tool (arc, circle, polygon etc). The lineweights in layer control are all 'default'. I can't explain this as it seems to have just happened. Is it a known bug or something?

When I import shape files the polylines will not take the layer style I move them to. They stay a continuous linetype. Linetype and Lineweight is set to ByLayer. Only difference between the new lines and the lines drawing correctly is the lines that stay continuous are 3D polylines and the correct ones are normal polylines. What I need to do to make the imported lines accept my layer linetypes?

I 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.

I want to turn this shape on the left, into one like the one on the right... i.e., not so many points.
I basically want to convert the polylines into arcs or something. i can do this by redrawing, thats no problem, but this is a very simple drawing compared to what i normally have to deal with, this is just an example.

Have recently upgraded to 2014 and can no longer get the AREA of a closed polyline in quick properties. It is no longer an option when customising the quick properties information. I know you can measure area in a number of ways but it was very handy to click on a closed polyline and have the area of that object come up in the Quick Properties window.
how to get the Area of a closed polyline in Quick Properties for 2014?

I'm having a bit of trouble getting my polygon closed without changing the dimensions of the polygon.The drawing attached or at URL....
However I do not know the radius of the angles A, B and C. I know that all the lines have to be the dimensions marked.
Can Autocad automatically bend the angle say, at A without changing the dimensions in order to complete the polygon? I tried this URL.... but found it wasn't what I wanted.

As the above mentioned, I have a drawing drawn using polylines with width from someone. The width of the line are suppose to represent area,
To put things into prospective, here is an example:
The polyline is 10 unit long and with a width of 2 unit wide. If i explode that polyline, it will become a single polyline without width. The line are suppose to represent 10 unit long and 2 unit wide; representing an area.
My question is is there a way to change the line above directly from polyline with width to a close polyline (4 x polylines) of 10 unit long and 2 unit wide.

Just found the issue with my AC2013.
A bit of difference is that the polylines do not have to be even closed. Any polyline gives me exactly the described behaviour, which is definitely not intended. Appears still not resolved.

Is there a way of converting 3d polylines to polylines with an elevation?
I have a dwg of contour information, the contours are 3d polylines, because they are contours the z value is constant all along the line, so there no question what the elevation of the polyline would need to be.
I need to do this as I then need to import the dwg into a GIS programme called MapInfo whch doesn't read 3d polylines.
I have access to AutoCAD 2004 or 2005LT.

I'd like to have a linetype that is a solid polyline with open circles every so often indicating a proposed field tile line. I'd also like to have the same line filled in circles to indicate existing tile.
How do I go about creating each line?

For example, I'm making revisions to a plan and drag a block or xref of the floor plan changes where walls/doors/windows have moved. I want to be able to simply pick the underlying linework as opposed to tracing over each line of said xref/block.

if I select a line, then enter the move command, the line unselects also when I select a line, then hit delete, the line is still there both of these used to work

My boss wants me to make the most outside line of a walltype to be the heaviest pen. If I go to the properties of the wall and changethe boundary it changes the boundary of the item in the wall, each boundary independentfrom the other. Such as a wall made of the following: BRICK, AIR SPACE, SHEATHING,STUD AND GYPSUM BOARD. In this wall theexterior face of the brick and gypsum board need to be heavy.
