What I want to do basically is merge a couple of polylines (which have different widths and may overlap each other) together into a single 'shape'. I am calling it shape, but I think the correct term would be polygon.
The end result should ("from the outside") look the same as before merging, the only difference being that the polylines are now merged into one shape. Important note: it cannot be a polyline with segments of different width, I know AutoCAD supports this, but the drawing will be exported to a format which does not seem to support this (and the result then is a line with a single width - wrong).
Here's a mockup of what I want to achieve:
On the left are three polylines (PL1, 2, 3), where PL2 has a different width and overlaps the other two polylines. On the right is the desired result: a single polygon (NOT a polyline with variable width) in the same shape as the polylines.
I am trying to import a complex curve from autocad lt (in my case an airfoil), to create parts. I have drawn the curve in autocad lt as a polyline. Autocad lt treats the curve as a single object, and seems to understand it as a closed loop.
When I import the curve into Inventor lt, Inventor treats the curve as a series of unconnected line segments. What can I do in either Autocad lt or Inventor lt to get Inventor to treat the curve as a single object, so that I can then extrude it?
Basicaly I have a plan of a part of a city and I want to fill the houses with a solid hatch, I was wondering if I could do them all at once instead of picking an internal point one by one (there are a lot of them!).

From my point of view, the function would be to:
- hatch every polygon of my drawing
- for each hatch do
- extract area and put it in an array with the variables (name of polygon and area).
And then is it possible to save it in a DWG or DXF file in order to reuse these areas by another program ?
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 have a series of boxes or polygones that I would like the program to find the 1/2 distance and create two seperate polylines from the one object.
Example:
I have a square with pt1,pt2, pt3 and pt4 respectively. After I have ran the program it would create a diagonal from pt1 to pt3 and join the rest of the lines now to create the one polyline. Also it would do the same to create another exact polygonal shape for the other half. Thus creating two shapes of equal value from one.
I'm trying to create about 150 cross-sections, each consisting of 9 closed polylines of which I have created the coordinates. My issue is making the list of coordinates create separate polylines instead of one enormous polyline. Any way to setup the columns, perhaps with blank rows, some way of applying ASCII code, etc. to automatically break up these polylines? (even if they aren't closed that's fine, I just need to make the polylines separate.)

View 8 Replies View RelatedJust 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 an option or a lisp routine to create a 3d boundary from closed 3d polylines?
View 8 Replies View RelatedI need to segregate closed polylines in my drawing by area range. Ideally, I would input the number of ranges I need.
Then somehow find the smallest and largest pline area to determine the range values (rounding up to a sensble number)
Then with the ranges determined the polylines would be segregated and moved to new layers.
I've been trying to hobble together pieces but with no joy.
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.

View 6 Replies View RelatedI've got ObjectIds of a bunch of arcs that I need to convert to polylines for further processing.
I was thinking of using the COM interface and sending the PEDIT command and converting the arcs.
The only problem is I don't know of a way to put the objectids into a selection set, then call the pedit command and use the previous selection.
On my file I have some polylines that are the streets. So, they look like rectangles and curves, etc. I am working also on a 3D Model, and what I have to do next is to extrude them. The problem is that those polylines are not polygons, and so, they are not solids when I extrude them. I tried to use the command BO but it says that the lines are not closed, and I checked with OSNAP and they are! Is there any way to convert those polylines into polygons?

As they are different by their colors (blue = lake, green = forest, etc), I would like to know if it is possible to convert these image to have an polygon usable in autocad, where I can calculate the area of each type of cover.
