I have a inserted block with 4 tags for Length, Thickness, Elevation and Width.How can extract attributes tag values and draw a closed polyline + 2 internal lines, parallel to the block?
Block Name: ID_DATA
Tags: LEN, THI, ELE and WID.
Each internal line placed in a third width.
Is that possible to have a lisp to extract the Field Expression of a attribute in a block?Specifically, to extract the property VALUE (TextString) of this attribute.After to extract, I would like to put this text extracted in a different layout tab, in the same drawing. In this way, I will have a text linked to the attribute value between two layout tabs. So, when I have to change the attribute value, the text will be updated automatically.
I know that if I use the FIELD command to manually copy and paste this value it will work, but when I have a lot of attributes it becomes very laborious.
I was wondering if it was the COND statement that I would need to use to evaluate a block to confirm that two attribute tags existed and if so, if would process the block to perform an attribute extraction of both of those tags. It would ignore blocks that only had one or the other attribute tags - and only extract the attribute values if the block had BOTH of the tags present - It could be blank, but it had to exist.
For example, I want to find blocks that have the attribute tag "PART_A" and "ID" - and then create a CDF that has the value of "PART_A" in the first column and "ID" in the second column. Then it closes my CDF file.
Then, I want it to scan my drawing again for blocks that contain attribute tag "PART_B" and "ID" and then re-open that CDF file and append the values so that the values of teh attribute "PART_B" is in the first column and the values of the tag "ID" are in the second column.
I have been playing with the following code --- is there anyway to modify the code to get it to do what I need? I have already removed the part that writes the header-row....
is there a way to draw a polyline and have autocad clip everything outside of that polyline and discard it so that i end up with a smaller drawing. only the information in that polyline, nothing outside of the polyline

Why dont draw de _pline?
I have drawings with a lot of polyline objects. I need a routine which will draw multilines by coordinates of vertexes of this polylines. For example, if there is a pline with coordinates 10,10 - 20,20 i want to draw in other layer MLINE with the same coordinates. I know it's should be simple but can not gues how to do it. I've never used LISP before.
View 5 Replies View RelatedCan a AutoLISP command be written to read an attribute in a block and draw a circle with the attribute as the diameter using variables? The appilcation is taking the diameter of a tree trunk (the attribute), multipling by 12, and drawing the canopy circle on hundreds of those blocks. So the circles drawn will vary in size.
Not sure how this could be set up, i'm not familiar with LISP writing at all.
1) Read block, single, mulitple or definition?
2) Read Attribute
3) Varaible of attribute, (attribute is an inch measurement...it needs to be multipled by 12 to get feet for final use as circle diameter drawn)
4) Draw circle, variable, with diameter coming from attribute variable (attribute in inches that is multipled by 12)
5) Center point or circle to be block's base point
I would like to take all the vertices out of a multiple-vertices polyline so that it reduces to just its start and end points, can this be done?
View 4 Replies View RelatedDue to modeling purposes, I need to convert a 3D polyline to a spline. What I have been doing is:
- change polyline fit/smooth to cubic from properties
- convert polyline to spline by typing spline -> object
- method -> fit from properties
You can see the original 3D polyline (green) and the resulting spline (magenta) in the attached drawing.When I zoom in and measure the distance between the two entities at different points along them, at some points the perpendicular distance exceeds 5 millimeters, and I want to ensure the deviation remains under 1 millimeter or even less.
I know I can change the knot parameterization of the spline, and this does work at some locations, but the difference increases at others.Why is there a 5.6 mm difference between the spline fit point and 3D polyline vertex, as measure in the attached drawing?
Now, I can go and manually stretch the fit point to coincide with the vertex. Also, I can add fit points between existing ones to drag the spline closer to the original 3D poly.
However, some of my polys are really long, and it is very time-consuming to do this manually while measuring points along the entities to make sure the distance stays small enough.
how to automate this process? For example a lisp that would maybe take the original vertex points, add say maybe 3 (not too many) new ones between them, and then generate a spline while making sure the deviation is less than the set value of 1mm? I am using AutoCAD 2013.
I wanna transfer my attribute block values to another attribute text blocks , is there any lisp for that?
Is there a possibility for sum tag values of choice attribute blocks to inside of another attribute text block ?
Background: Someone exploded an attribute block and copied it hundreds of times throughout a project, each time changing the Attribute Tag to match the Value they expected to appear in their drawing. The drawing must be xrefed, so the attribute definitions do not appear.
(There is only 1 attribute in the block.)
Proposed Solutions:
1:AutoLISP routine which copies Tag data from Attribute Definition into Value of Attribute Block:
Prompt-Select Attribute Definition
Copy Tag data
Prompt-Select Attribute Block
Paste data into Value
(Allow repeat to speed workflow)(*PREFERRED*)
2:AutoLISP routine which copies Tag data from Attribute Definition into Default Value and creates a new Block:
Prompt-Select Attribute Definition
Copy Tag data
Paste data into Default Value
Create New Block
(Select Multiple Objects)(Creates tons of new blocks which are messy)

I have a drawing that has an aerial Images inserted into it using a WMS Connection How to extract Image Name through Autolisp from this
View 5 Replies View RelatedI am trying to write a lisp file that extracts the LAYER, Z, X, Y, TEXT HEIGHT, POINT NUMBER, from the attached DXF file. Ultimately I will have the lisp insert a "POINT" at the X,Y,Z, cords, and then a "TEXT" entity at the same coordinates with the text height value and the point number string. Both entities need to be on the layer ending in "-PN". The layer name will change depending on the date. I have a third party program that creates the DXF file.
The point of the lisp file is to insert the point numbers and points into my drawing at their correct locations. For the life of me I can not make this work. I have attached the little bit of lisp I have, which unfortunately does not work properly because of it searching for the "TEXT" entry in the DXF file of which there are three per point number. I only need one. I have also attached the DXF file I have. maybe just an overall procedure that I can then code myself? I'm just not good at getting lisp to read a file and extract what I want from it.
I would like a lisp routine that can extract and export the x, y, z coordinates of all the points in a drawing into a text file so I can use the same in excel.

A quick lisp routine to extract the elevations of a selection set of 2d polylines? I have a massive "contour" file composed of 2d polylines with elevations.

View 9 Replies View RelatedI've got a linetype that's part of our autocad template file and has been for so long that nobody around here even knows where the original line file is.
I need to extract the linetype out so that I can make some minor modifications. I did do a search and found a nifty lsp routine from Paul Turvill. (Here's the thread that pointed me there: [URL] ..........
I ran it and it SEEMED to work. All the linetypes in the file it created look good EXCEPT for the one I needed to extract. That one looks like this in the line file:
*TREELINE,Series of arcs used to indicate tree drip lines
A,0.0001,-0.0001,
The linetype DOES display properly in the dwg file (meaning lines drawn using it look good).

I'm dimensioning an old drawing with the real (measured) dimensions and with the drawing dimensions in brackets (using ' 1500 (<>)' to give '1500 (1505)' for example.
What I'd like is to also be able to put on the difference between the length I type in and the length in brackets - as this would let me see any really glaring errors that can't be attributed to user-error on the laser measure.So I could type in '1500 (<>) (X)' where X is the formula, and get ' 1500 (1505) (5)' back?
How to be able to run a script that could highlight any dimensions where the number is brackets and the typed number have a a difference of, say, 50.Or failing that, any way to extract all the dimension text at the end into excel so I can see the differences myself?

So looking for lisp doing that automatically. I mean, invoke the command, set the first elevation and them select the polylines.
e.g. The first elevation is 530. The next polyline that I select is 531 and so on.
For the sake of editing, I sometimes make LWPOLYLINES and convert them to regions so that I can union and subtract and intersect, etc.
then sometimes, like now, I want to work with them like as LWPOLYLINES again.

Say I have a block that contains two attributes, one contains a value that is a number and another contains a value that is letters. I have many of these blocks placed in a drawing, could you create a lisp that would return the sum of the number value and return it to the command line along with the letter value. Something like this:
Sum--------Item
