I'm using VB.NET to write a routine that autmatically calculates the area of the polyline nearest to a block (the pline surrounds the block) an then adds the area to the blocks attribute.
I managed to write the program to do this manually for a selected pline and block.
How can I automatically select a pline nearest to the selected blocks' insertion point?
How do you find 'if' a polyline is inside another polyline?
View 2 Replies View Relatedi have a set of coordinates, not on the polyline. i want to find the polyline width where that coodinate intersects perpendicular to the polyline (shortest distance). without going through all the vertices.
i have a polyline with many segments with varying width, which are constant through the each segments (no taper width). need to read off the "instantaneous" width.

I am trying to follow some directions and the call for a spline to be drawn onto an image. I can only find a polyline which doesnt work like I need it to. As I understand it a polyline will put a curved line as close as it can to a series of points, whereas a spline will "join the dots". I need to join the dots but with a curve not a jagged straight edge.

How do I find the start or end point of the polyline with program? I am thinking to check all points which is not shared by two lines.
I have a weird problem with exploding block reference with vb.net as follows.
When I use BR.explode(DBObjectCollection), and append the entities in the object collection to model space,
the 3d Polylines inside the block reference do not get appended and I do not get any kind of error. The reason for this eludes me as of yet. (remember, simple polylines and lines and other objects do get appended to model space)
When I use BR.explodetoOwnerSpace(), the block reference explodes as it normally is expected to, but then I have no way to collect the objects from the exploded BR.
I have several polylines in block format. I need to shorten the entire block: 40' to 20'. I'm guessing I go into block editor?

I'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.

I have a polyline which consists of straight lines and curves in 2D enviroment.
I want to extract some coordinates. I usually use block refferences and "dataextraction" command. However, the problem is as follows:
I need to mark many things along the polyline's way at no constant intervals (not possible to "measure" it) If I have "osnap" on, I can't hit the spots I like for obvious reasons. If I have "osnap" off, I can't place the object accurately on polyline's way.
So, what I need is: how to allign multiple blocks to a said polyline. Allignment needs to be done as accurate as possible, prefferably perpendicularly to closest tangent of polyline.
I would like to explode a polygone I've created within a block.
But I get the "_amexplode This command is not allowed while the REFEDIT command is active."
Um so, I have to explode the block, explode the ployline/polygone and recreate the block.
Or, I could minus the polygone from the block set, save the block, explode the polygone, reopen the block and add the lines back in.
I don't see an explode option in the "pedit" options.
Am I missing something here, is there more than one explode command now? It worked in a previous version.
I have a dynamic block with several look-up values for the polylines width and I'd like to label them (as a text in the drawing over the block), and be able to move this label where best fits. I've being trying inside the block, but then it can't be moved outside of it. I tried MText with field outside the block, but it has to be applied in many one by one.
Should I use the block itself (how?) or there is a lisp for this? I have a lisp for bearing and distance for lines, which places the bearing text above them and the distance text below those lines, no matter what angle is. It will place in the middle and in the same angle as the line. I edited this lisp file, but how to change it for my purpose, as I don't understanding all the codes inside of it.
I want to make a block with dynamic attributes. Basically I have some polylines on my drawing which represent cables, and I want to have a block with a legend on each polyline with 2 values. First will be the cable type which I would enter manually and the second value will be the length of the polyline. Is there any way that the block would read the length of the polyline and dynamically change the 2nd value?

View 3 Replies View RelatedI've have code to test if the insertion point is within a closed polygon. But prior to testing the insertion point I use ssget to trim the selection set initially..

I'd like to set up a blockwith different attributes like Roomname, Floor, Area,...
Therefore I'd like to link a polyline of the drawing with the block and it shows me its area. I know how it works with fields, but not how to connect it when the field is within a block.
Is there a LISP for that?
I am starting with a polyline then i use the pasteblock command to insert that polyline as a block.Now i can pull up the property box and change the xyz scale.
I would like to know how to change these setting in my lisp.The scale will be x=1 y=0.1 z=1
where I can find a SIMPLE 3d man block? All the block exchange websites have fancy ones.
However, I would like a fancy one of a child standing.
Does any Lisp routine available to batch replace all the closed polylines with an existing block?

I can run through the entire xref object and find the block - by name - but is it posibel to search direct like searching in the main drawing.
I have several blocks spaced evenly apart and I need to copy and paste another block and insert it with the same spacing. I don't want to take the step to find out how far apart they are. I believe there's a way to use the insert command to figure out the distance the next block needs to be placed when I paste it.
I'm not sure if I'm describing it correctly or if I can paste the block using the insert command.
I inserted a block into a very busy drawing. I can't find it now. Is there a way to locate it? I want to delete and insert a newer version, but I can't until I delete this one.

I know of DIMRND, but how is it possible make acad round dimensions UP (within a specified value) instead of to the nearest?
(This could be very handy to make various lengths of wooden baseboards and other mountings fit to machine cabinet standard lengths. I'd like to keep all the work in acad, and avoid ms-excel.)
My "Nearest" osnap is not even close to snapping to my circle. All other snaps are working fine, nearest snap are working on lines and rectangles, not at all on circles.

tool palettes from a directory called ACAD2008 to ACAD2012. Tool palettes can't find the associated blocks because the support path still points to the ACAD200 Directory.

there is a way I can get NEAREST snap to work on the multileaders?

Can use NEAREST on normal leaders though.
Running AutoCAD LT 2013 on Win 7 Pro.
I am looking for a way to get my dimensions to round up instead of to the nearest.
For example... when I have one line that is 11-15/32" and one that is 11-17/32" and I need them to round up to the nearest 1/4". I want it to round up, showing 11-1/2" and 11-3/4" but instead i get 11-1/2" for both.
Is there an expression that will allow a parameter value to be rounded down to nearest 0.125.

Is there a way, when you are drawing a polyline, to have the tooltip box show the cumulative length of the polyline, rather than the length of the current segment being drawn?
