I'm wondering if there is a lisp possible to measure area's by pick point (as in bpoly). This little feature exists in Microstation so i was looking for something similar.
Is it also possible if this lisp can measure areas from an external reference (dwg, dxf, dgn, shp etc..)? I'm kind of new to AutoCAD in that sence.
I have a lisp routine that I would like to add to. Right now when running the macro the user is not prompted to "Pick Point On Line" in this example
(command "insert" blk "s" var1 pause pause))
I have added the line
(setq pt1 (entsel "Pick Point On Line "))
(command "insert" blk pt1 "s" var1 pause pause))
but the command doesn't seem to like my PT1 value
BLK and VAR1 are set in another lisp routine.
I am looking for some code that would allow me to select a MTEXT Entity - or other entity - (as the DEFAULT option) but also to allow me to type in some text manually or to pick a point in the drawing. Something that would present the user with:
"Select an object or [P to pick a point]" or
"Select MTEXT or [M to type].
I can write some code to type in text manually as the default option and get the second option to select entity using get string and then write some condition of if code but I don't know how to do it having entsel as default option.
How would I go about this. if a two blocks or polygons are overlapping area?
A good method or the algebraic formula for a function to tell me if a point is inside a polygon or block's area?
I know how to increment pick points numerically (see below). How is it done alphabetically?
(defun C:test (/ pt# pt) (setq pt# (getint "
Enter number: ")) (while (setq pt (getpoint "
Specify point: " ))(if (/= pt nil) (progn (command "TEXT" "M" pt "" "" pt#) (setq pt# (1+ pt#)) ) ) ) (princ))
I used to have a lisp routine that would allow me to pick one dynamic block and it would select all instances including the blocks that have become anonymous.
View 5 Replies View RelatedI like that Autodesk now allows us to just pick a command's option from the command line instead of typing a letter in the option. For example, when drawing a rectangle we're prompted to "Specify first corner point or [Chamfer Elecation Fillet Thickness Width]" and if we wanted to draw fillets on the rectangle we can simply PICK that option from the prompt in the command line OR enter an "F" and return.
Is there a way we can use this functionality in our custom programs?
Is there a tool out there that will allow me to pick an object and change it's layer properties?
View 9 Replies View RelatedNormally when applying the matchprop command in CAD, one has to first pick the template element, and then select the elements which should have this template element's properties copied to/matched.
is it possible (via lisp perhaps?) to reverse this order, so that i can select a bunch of elements (e.g. through the quickselect icon) and THEN apply a matchpropertieslisp command, then select a single template element which the initially selected elements should mimic?
do you know command or lisp that will do new pollyline between two polyline on 1/3 or 1/4 space between them.
I need sommething that would be faster,know is use measure on pollilines then i draw between horizontall polylines on verteks or point new pollyline and then divide it on 4 or 3 parts.
I am trying to create a lisp that prompts you to select multiple lines, and then prompts to enter a name of a block you wish to use. With that information use the measure command to place the entered block along the selected lines with the spacing set to the value in the blocks attribute.
I have a lisp that does most of this with the exception of the extracting the value of the block size to use as the distance between blocks, the current lisp just prompts for the distance.
I have a lot of blocks with different spacing so it is hard to remember the distance.
Here is the current Lisp i use:

The attached lsp puts tick marks at equal distances along a line/polyline and tags them with the distanace value from the start point. I draw using millimeter units but things like chainage should be displayed in meter units. Using this routine displays the values in millimeter units which I then 'find and replace' to edit their values to meters.
Take a look at the lisp to see if it can be altered to input the mm value at the start but output the meter value to the text values?

I am in need of a lisp routine which will automatically pick up all hatch and solid hatch patterns within a drawing and change the colour to colour 254.
View 9 Replies View Relatedi've got a lisp-routine that calulates multiple area's and put the sum in text in the drawing on the place i select.
the sum has to be devided with 1000000 so that it is in m2.

I have a lisp I use to calculate the area of an object. The section below is the area part of it:
(setq ojt (entsel "Select object to get area of... "))
(command "area" "o" ojt)
(setq oarea (getvar "area"))
I want to modify it to add the areas of multiple objects. Unfortunately it is not as simple as;
(setq ojt (ssget "Select object to get area of... "))
(command "area" "a" "o" ojt)
(setq oarea (getvar "area"))
So how would I go about doing it?
I would like to be able to draw squares by the area they should have. So that if I need a square of 50m2 autocad automatically draws a square of sqrt(50) x sqrt(50)
Because right now I have to draw 200 squares with 100 different areas and I have to calculate and manually draw each one of them.
I have a closed polyline that i can add the area to via a field in mtext using the options under area. I would like the area to always be rounded down to the nearest square meter. Is the a way to do this via the acfields.fdc file?
View 8 Replies View RelatedI'm trying to find acceptable point values to feed to the vlax-3d-point function for a vla-addmtext function. With vanilla lisp I just provide the point as x y = "7/32" "2-3/8". So I assumed that I could drop a 0 in for the z like: (VLAX-3D-POINT "7/32" "2-3/8" 0).
Then I thought I was going to be tricksy and try (vlax-3D-point (getpoint)) believing that I could pick the point and get what I need to feed the function, but yet again, no deal. The command line gave me:
node
of #<variant 8197 ...>
Nothing I can use in my code. So how do I find the point in a format that vlax-3d-point will like?

View 7 Replies View RelatedI have many floorplans and each room has a polyline around it.
What I'd like to do, is be able to select multiple (or single) polylines and have a dynamic field with the area attached to each polyline placed in the middle (or on a consistent edge, say top left). Preferably with custom units as we use mm for the drawings, but would want the area in m2. Also custom text heights.
I can find a lot of 'put the area in the middle' scripts, but they're either not dynamic or they require a click to place each one - and with over 700 floorplans and over a hundred or more rooms on some, it's not really possible to do each one individually!
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?
Find attached 2 files , a DWG and a LISP
The dwg show a LWpoly, and 3d-poly.
I try to get the param at the closest point, from each vertex at the LW, at the 3d-poly

know a lisp routine that would insert a block @ a specific point on an arc? For instance if I have an arc that has a radius of 20'-0" & I want to insert a block at a set distance from the end of the arc.i could probably use the divide or measure command but I was hoping I could do it with lisp. I would also like to be able to move the object along the path of the arc at a specific distance.

I know VisualLISP pretty well, definitely well enough to accomplish the task.but...I can't figure out how to retrieve information on the point cloud's clipbox using lisp.
I know a little VB.NET; I took a one-semester class at the JC, two years ago. It's going to take time for me to get ramped up enough with VB to do this job, so I don't really want you to tell me the only way to get to the clipbox is through vb.

I need a lisp that creates a polygon of N points, so to enter a only the distance between these points, after choosing N points in the drawing for approximately creating polygons.
View 7 Replies View RelatedI need a routine that inserts a point at the insert point or block named "Insert_Point" at every block in the file. The routine could use the current layer, which would be set prior to starting the routine. If it could request the user for the PDMode value and PDSize that would be great too. This will assist me in creating block libraries.

I 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.
