I implemented astar using a heap instead of the dictionnary proposed by @GLAVCVS. Safearray is used to simulate the heap. Was done with prompt in Google AI.

Your points will fall on the grid lines not inside the boxes created by the grid lines.

In other words, you are having trouble understanding the concept of interpolation, correct? The mathematical interpolation of contours goes like this. Let's say we have two spot elevations A & B. A = 32.7 and B = 54.0. The distance between A & B = 50 feet. We want to know where our 40-foot contour would fall between spot elevations A & B. First obtain the total elevation difference. This is done by subtracting A from B. 54.0 minus 32.7 = 21.3. Next, we want the difference in elevation between our 40-contour interval and the nearest spot elevation which in this case is A or 32.7. That works out to be 7.3. Now we need to calculate the distance (let's call this "d") we need to go from spot elevation A to our 40-foot contour. That takes the form of: d/7.3=50/21.3 or d=7.3*50/21.3 = 7.3*2.347 = 17.13 or the distance, in decimal feet, to our 40-foot contour. Got all that? Good. Now go start interpolating.

I am not good as the others but try this. It will build what you want to achieve but not exactly as what was shown in the image. Maybe other can improve the code.

Nice program as always Tharwat. I think what the OP need is create a table as attached for visual reference.

I would ask that you delete your drawings. Why? Because another student could come along and borrow them, make minor changes then submit them as their own drawings thus saving hours of labor. You do all the work and they get the credit. Not kosher at all. Follow me? Addendum: Looks like someone has already done exactly that. Again, take your drawings down. There are plenty of image files (not CAD files for students) to reference. Thank you.

The OP seems to have exited the conversation, but just for others with the same inquiry. As I have mentioned, this is mostly an issue with your PDF editor, the instructions for using the OCR should be in Foxit Help. If this is something you need to do going forward without any effort, you need to use TTF.

As most of us use Microsoft Office products I switched from using AutoCAD's Swiss Lt BT TrueType font to ArialNarrow.ttf like SLW210 suggested as it's horizontally compressed to take up less space while being even more easily readable. While hindsight doesn't fix your immediate problem finding a font that doesn't cause issues with your PDF software before you need to output one to PDF again would solve your issues in the future. I've struggled with the same issue even with the full paid version of Adobe with drawings by others usually because of SHX text with various width factors. Never do that with a DWG you want to output to PDF unless you don't want anyone to convert that text back again.

I opened your PDF in Acrobat Pro and the text was editable. This seems to be a Foxit issue, though as mentioned, you might want to use a TTF font if that's what Foxit needs. ArialNarrow.ttf is a common replacement IIRC to ISOCP.shx

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.

Sorry, I've been out hiking. It appears to be correct. Question: Have you already calculated the location of the 80 ft. contour that occurs between the spot elevations of 88.9 and 93.8? There is also a 100 ft. contour and a 110 ft. contour that starts on the same grid line.

If I understood the request correctly... This could be a design start, it uses the oblique block of the dimension.

You might try Lee Mac's Steal from Drawing | AutoCAD | Autodesk App Store. I just do a SAVE or SAVEAS on the drawing and make a new exact COPY of the drawing. If I have similar drawing that could use the other viewport and settings, I just drag the Layout from one drawing to the other with Design Center. There is an Export Layout to Model... when you right-click a Layout TAB and before that option was in AutoCAD there were some programs that would do that. To do what you want looks to be a lot of work for a LISP.

You need to use ERASE to remove items in order for OOPS to actually restore it.

That's because you need to do something before issuing the oops command. I think there is a thread here differentiating oops and undo command.

You created this thread before even trying it in your AutoCAD?

Did you google found lots of ideas.

In this link, it's written that OOPS command exist : In AutoCAD since version ≤ R12...

Bit odd yes tested in Bricscad, I will look at the getcellextents, this gives the XY position of the corners of the table cell. If the line is 69 times repeated it sounds like that is the problem. I will make a little test program so can look at what is going on when calculating the Pt1 and Pt2. the code is done that way so if row height is changed for other users the lines are still central in the cell. Add the (princ line and look at the Y value displayed, it should change for every row. Please let me know if it is not changing. (setq pt2 (list (nth 6 pts)(nth 7 pts) 0.0)) (princ (strcat "\n" (rtos (cadr pt1) 2 3) " ")) (setq vdist (/ (- (cadr pt1) (cadr pt2)) 2.0)) Another test could some one try on Acad. 0 is 1st column. (setq objtable (vlax-ename->vla-object (car (entsel "\nPick a table ")))) ; put a number like 3+ in row variable ; then copy this line to command line change the 3 etc to 4 5 6 and so on ; The Y value should change (setq pts (vlax-safearray->list (vlax-variant-value (VLA-GETCELLEXTENTS objtable 3 0 :vlax-false))))

Works with BricsCAD. I know you have to wrap points in AutoCAD sometimes with (vlax-3d-point pt2) not sure about entmake tho.

Thanks!! it's working fine. It's okay if it's not exactly the same from mine but as long as it can generate the table it's fine. saved me a lot of time.

Thank you I can use this as well...

yah it is... I overlooked it. All good now.

Gotcha, thx Remark

not sure what your trying to do. you can set entlast before the explode then add all the entities into the selection set. (setq LastEnt (entlast)) (command "_.explode" ss) (setq SS1 (ssadd)) ;create a blank selection set or add to an existing one. (while (setq LastEnt (entnext LastEnt)) (ssadd LastEnt SS1) )

I tried this as a test, so finds the #1234 text. It will find 123#456 also. But the lisp as suggested by @Steven P should cater for that. (setq ss (ssget "X" (list (cons 0 "*text")(cons 1 "*#*")))) (princ (sslength ss)) 12

Unfortunately not with the current version, but I'll certainly consider implementing this functionality in a future version.

In PDF-XChange Editor, I could only edit the Title Border Text. All the node text isn't editable. Using OCR in PDF-XChange, it converted all 5 pages in about 15 seconds. I am using the paid-for version, so not sure if OCR is available in the free version.

Just do a google you should be able to find a ISO.TTF font there are thousands of fonts out there. You open c:\Windows\fonts and drag the TTF onto it from memory. ISO3098B ? If your lucky some one may have one already.

I can do that most of the time with the OCR (Optical character recognition) in Adobe Acrobat Pro. I thought Foxit has an OCR.

You may not have a choice here, but can you convert your text to TTF from SHX? PDF should accept that as text.

Not sure if this will work the way you want. I created a dummy drawing with a dummy block and a dummy attribute. When you set the attribute to Invisible, you can't see it any more, but you can edit it. I know, that's not what you want. I include it so you don't waste time trying it for yourself. When you set the attribute to Constant, you can't edit it at all. It no longer shows up in the Properties, and it doesn't show up in the block. If you change the attribute back to not constant, you can insert a new block and give it a different value, but it's still invisible and it does show up in Properties. Could be a bug? Or the way I handled it.

I use the one in CadTools and it has window that opens and you can adjust the parameters and create a custom vehicle.

Have you looked at: https://www.lee-mac.com/batte.html

My fault for not stating all the angles were to be measured CW or CCW from 0°.

Indeed, it is sir. Thank you for looking into this issue of mine. Although I'm not certain of what causes the error that I'm seeing, I have the same "Macro" written out on one of my gaming devices, it works, until AutoCAD becomes a dyslexic child. That caused me to look for an "internal" method to AutoCAD. Starting at around 2°, these were my results this morning. Multiple completely different random starting lines. I'm not sure what you mean by changing the start point, I want it to start on the 0° axis from 0,0. I do not use "Dynamic Input" or "Dynamic UCS".

You need to understand what is a OEM version it is used by software providers as a means to get an Autocad but with their software as the essential item. Refering to OEM document "Deliver products with scaled feature sets at scaled price points and provide an AutoCAD-based platform that cannot be customized or extended by end users." So any outside program lisp or .NET etc can not be ran by you. But you can add programs using the OEM key that is held by the software developer. You would have to go back to them to add. What program did you buy ?

Ok its simple to use vpoint to set your view angles, code is part of a view choice lisp. (if (= look "R")(command-s "-vpoint" "1,0,0")) (if (= look "L")(command-s "-vpoint" "-1,0,0")) (if (= look "F")(command-s "-vpoint" "0,-1,0")) (if (= look "B")(command-s "-vpoint" "0,1,0")) (if (= look "P")(command-s "-vpoint" "0,0,1")) (if (= look "3")(command "_.vpoint" "-1,-1,1")) If you want auto 3 viewports then you need to ask what scale and pick say a point in model so the views can be based around that point. I would use a layout with a title block.

I like using foreach to step thought a selection set or if you need the vla-object (foreach ent (vl-remove-if 'listp (mapcar 'cadr (ssnamex SS))) ) (foreach obj (mapcar 'vlax-ename->vla-object (vl-remove-if 'listp (mapcar 'cadr (ssnamex ss)))) )

Another very useful is "Entmake functions.lsp", it has various entmake functions in it. Maybe make a word doc etc of your functions describing what they do. We had a "how to directory" with lots of help files. Was thinking about doing macros in Notepad++ run ents, run ss, ssl for layer, ssi for insert and so on. This is a common one. (repeat (setq x (sslength ss)) (setq obj (vlax-ename->vla-object (ssname ss (setq x (- x 1))))) ) Posted this before. Lisp files Apr 2024.docx

How to export, import, backup, and transfer settings to and from AutoCAD products Though if the old computer is unusable, you may have to just start from anew.

Steps after typing STL at the prompt to start the program: 1) Select the Shape button (in your screen shot you selected Pipe-Std 2) Select the View you want (2d end etc.) 3) Select the size from the drop down Size table. 4) The OK button will now be available, and you select OK. 5) The dialog box will go away and you select a point on your drawing to start the shape. Each shape has a different starting point. 6) Doubly symmetric shapes like pipes will draw the shape 7) Singly symmetric shapes like angles will put the shape in and you can rotate it as you like dynamically. 8 ) To draw another shape, you type in STL again and repeat as needed.

You’re welcome Tom. I forgot to say that if you are unable to install the 2021.1 update, then second choice is to set the AutoCAD system variable LISPSYS to zero and restart AutoCAD. The caveat is AutoCAD will then use the old VLAIDE rather than new Visual Studio. Steve Doman

yes, ATTSYNC is the magic command. If you update blocks with attributes you only change future blocks, not those already in the drawing. The ATTSYNC command syncronises all blocks to the new definition. It is possible to do a lot of damage to a block by deleting attibutes and not attsyncing it - and there have been plenty of "help me" requests here to prove it.
