Try this as a first pass, see if I have the idea right: Not quite as described and only draws lines as it is, rather than Polylines, but it being a Sunday and the CAD should be off it will do for a start, or if it inspires anyone tonight. To consider later: Fixing the loop - as it is just escape out of the LISP to end or join last point to start point. Join the lines together as Polylines (See Lee Mac PLJoin?)

I use this Lee Mac lisp. I find it very useful. It's not exactly what you're asking for, but it might be a big help. https://www.lee-mac.com/3pointrectangle.html

look into dynamic blocks

I've always set Plot layout for plotting for that reason and set Plot to Center as well so if a plotter with different margins was used it would still plot exactly the same way.

No idea, it was up and running a day or two before. No explanation other than "If you have any questions, please contact AUGI."

Many years ago "Civilcad" software had that function, draw a shape and click on boundaries you could do things like set a side and slide along that side with updating offset to other sides as one option. So understand what you want but no solution, sorry. Not sure if it ended up in current software "Magnet". Note in the image the offset line to the angled line., it will always be the closest corner and changes automatically depending on the shape. Welcome to Cadtutor. Post a sample dwg with some examples of what your looking for, a before and after is best.

Do you remember what the command was to run the LISP - you never know, someone might have a copy or a link to it

Really? Was an explanation offered as to why?

I moved your thread to the AutoLISP, Visual LISP & DCL Forum.

I'm a land surveyor. Years ago I worked at a company that had a script or lisp to draw a house. Basically you started a polyline and then drug the cursor the direction you wanted to go. Then you would put in the distance. Then you simply type the next distance and would draw that distance 90° to the right of the last line. Or if you put a - in front of the distance it would draw 90° to the left of the last line. Or you could add / or \ to draw 45° to the last line. You would continue until you are done. I would be willing to pay $$$$ if someone could write this for me.

Once I made your MText large enough it was very visible. Try placing the MText in PaperSpace.

Another way to approach this ";; Loop through vertices" is to get all the vertices and simply use those XY values of the corresponding two points in a repeat. You can check the readabilty of the answer by looking at the angle of the two points, so place answer above or below. There are plenty of label plines out there do a google, "Kent Cooper" has some good ones. may be faster than debugging what you have. setq plent (entsel "\nPick pline")) (if plent (setq co-ord (mapcar 'cdr (vl-remove-if-not '(lambda (x) (= (car x) 10)) (entget (car plent)))))) (princ co-ord)

This question has been asked before. Do a google or search here. I remember posting something.

In the future please place your code in Code Tags. (<> in the editor toolbar)

Ok. Guess they changed it.

When I have a viewport that show a 3D object and have to change the visual style to anything but 2d wire frame, any text I put inside the viewport box disappears. Anyone know how to fix this? TEXT_MISSING.dwg

Do you plot using the AutoCAD "plot" function? Or a LISP - the OP had a LISP to plot with (?) which might have been an issue and is this a new thing that is happening?

Oh its ok, in one part of the guide, it says the following: "Create contours at 10′ intervals for just the 100′–180′ contour lines" So I thought I would only work on the points ranging from 100 to 180. Could I be wrong? Thank you very much for the guidance. I already know your instructions, and this is what I did. Could you tell me if this is correct?

Hi, thanks for the offer. I am doing exactly that with my blocks. I directly data extract to an excel file and that I find to be the most convenient until my blocks got corrupted after which the blocks stopped showing up in the data extraction menu box. I am familiar with data extraction of the blocks. The root problem is ZWCAD does not allow data extraction of the contents of mtext or does not data extract mleaders at all, which is why I had to create the dynamic block. I really want to know why the dynamic blocks get corrupted and if there's a way to return it back to the original definition of the block. I found out recently that a fairly simple dynamic block I made within ZWCAD got corrupted too. I am reattaching the Issue.dwg with some more information. .

OOPS only restores objects that were erased by the last ERASE command.

Just my $0.05 there was another post about doing breaklines maybe at Forums/autodesk/lisp. One answer provided had multiple break styles that looked very useful. I will spend a couple of minutes and see if I can find the link.

Welcome to Cadtutor. !st step run AUDIT and look for errors. 2nd ? In this problem case I use Notepad++ a text editor its free, it has a function "Compare" so you can compare two files, in the case of CAD you look at all the variable settings. You use a Log file, the command LOGFILEOn starts it LOGFILEOFF stops it, you run it on two different PC's. The log file is located in your temp directory under Options Files Temporary directory. 3rd you may want to audit the Xrefs. If your happy can you post the dwg here so we can try to find problem.
