NextGen Gallery Template V2 for captions under thumbnails

Unfortunately the NextGen gallery V2 templates documentation is a little confusing as some is for the old templates and some is about transitioning to the new. There is no basic page to explain what is going on. The best is here.

Thankfully there are really helpful people on the forum where they have explained various things.

Firstly I wanted to add captions below the thumbnails which was available in a standard template in the legacy setup but as they will be depreciating this shortly I thought I would set up the system properly with the new templates.

lheisey posted a very useful update on their issue which was the same as mine. Firstly you have to create the folder path as out of the box the install does not include this path, this can be done through CPANEL or FTP. The photocrati-nextgen_basic_thumbnails folder and its subfolder templates need to added. Full path is:


Then you will need to create a file in the folder called something ending in -view.php. Mine I called test-view.php.

The contents of this file will be exactly the same as the one found at:


But with some additional code added at lines 55 and 56 (thank you to PostmasterGS in this post), this is slightly different to the code in the post as I could get the text to be visible with just a span, div or even with nested paragraphs inside. A heading with custom CSS solved that. I have used ak suffix so I can track the changes.

Adjusted code:

<div class="ngg-akcustom"><h6><?php if (!$image->hidden) { echo $image->alttext; } ?></h6></div>

In context (snippet from whole file):

 width="<?php echo esc_attr($thumb_size['width'])?>"
                    height="<?php echo esc_attr($thumb_size['height'])?>"
        <div class="ngg-akcustom"><h6><?php if (!$image->hidden) { echo $image->alttext; } ?></h6></div>


The accompanying CSS:

.ngg-akcustom h6 {
    color: #777;
	font-size: 12px;

Upgrading to PHP7

Not a CAD issue but a website one this time. I decided to bite the bullet and change my PHP version for the website from 5 to 7. This caused an “500 internal server error” which was not that helpful.

I turned on debugging (make sure you tutn it off afterwards) and that gave a slightly more “useful” error – “PHP Fatal error: Uncaught Error: Call to undefined function mysql_connect() ” – that was almost as cryptic but one search later and the soultion was easy.

For what is worth, I encountered the same error and the issue was solved by enabling the nd_mysqli extension in the PHP 7 configuration, and disabling the mysqli one.


Just change the PHP modules and your are sorted. One change later and all is good! Thank you Francesco!

Revit Frozen Palettes

A colleague of mine today had frozen palettes in their Revit LT. The properties and project browser were not clickable at all.

The solution is not as we discovered to reinstall but to reset Revit LT settings by renaming the registry folder group for revit as per the following video.

  • Close Revit LT
  • Lauch regedit
  • Go to current User –> Software –> Autodesk –> Revit 
  • Find whichever Revit you use , for example Autodesk Revit Revit LT 2018
  • Change the name Autodesk Revit Revit LT 2018_backup
  • Launch Revit LT again and the palettes should now work!


World coordinates not where they should be

When using world coordinates on a project I found that most of the drawings overlaid exactly. However one kept coming in off the others when attaching against World UCS. World UCS set correctly and checking the actual coordinates (with ID point) everything checked out OK.

So what was the issue?

The issue was for some unknown reason the base of the drawing was not set to 0,0,0! It was rather wonky to be exact!

Type base to find out what the current drawing is set to. With pretty much any drawing but particularly world coordinate drawings is should be 0,0,0.

Wonky Base coordinates.

Base set correctly

Random glitches, flat ucs and icon solid hatch

A colleague of mine could not hatch dots on a drawing at a higher density. I tried the usual regen and measurement commands to see if it was the hatch itself, however it was not to do with this.

After searching it could be a variable issue in the drawing but the drawing was from our standard template, but worth checking to see if HPMAXAREAS and HPMAXLINES were set to low values. They were not.

After further searching it became apparent that the drawing was a long way from the origin causing the glitches. This was apparent because the x leg of the UCS icon kept disappearing on zoom when in world UCS.

The glitches were:

  • Hatches not hatching properly at higher densities
  • ONSNAP not working properly
  • Fillet and trim not working properly

The solution was to create a drawing UCS closer to the drawing that fixed these glitches.

Indesign relinking alters size of images

If you are importing PDFs of AutoCAD drawings into Indesign to say create a presentation and you update one of the drawings that has been scaled to fit in a frame and is exactly the size you want it to be and then you relink and run into the following problem.

AutoCAD drawing is the same scale 1:1. The plot is the same size and the plot scale is the same size but when re-linking the drawing you find Indesign has unhelpfully resized the image to a random size. This is probably really useful if you do a lot of swapping the same images around at different resolutions but not helpful in this case.

Here you need to change the preferences.Go to file handling and deselect preserve image dimensions when reloading. Thank you David Blatner.

Creating a default layer sheet

As part of my preparing an AutoCAD drawing for my office’s layering system I managed to insert layers into a drawing from Excel using only scripting.

However the creation of a line and a text on each of the layers, so that users can copy and paste to get the layers etc. into new drawings, needed full AutoCAD and its access to LISP to create these quickly.

The script below is a modified (larger text and longer lines) version of a script, kindly written, from here.

(defun c:lintextfromlayer (/ pt dat ln)
(setq pt (getpoint “\nSelect insertion point: “))
(while (setq dat (tblnext “layer” (null dat)))
(entmake (list ‘(0 . “line”) (cons 10 pt) (cons 11 (mapcar ‘+ pt ‘(5000 0 0))) (cons 8 (setq ln (cdr (assoc 2 dat))))))
(entmake (list ‘(0 . “text”) (cons 10 (mapcar ‘+ pt ‘(5200 -125 0))) ‘(40 . 250) (cons 1 ln) (cons 8 ln)))
(setq pt (mapcar ‘- pt ‘(0 1000 0))))


Excel to AutoCAD layers

I have been attempting to update our office’s layer system. This would be difficult to do in AutoCAD without resorting to LISP or some programming to insert layers on mass. Creating lots of text on mass is really easy to do in Excel so that would be the program of choice to do this task.

The problem then comes of getting these layers into AutoCAD? There are numerous Lisp programs around on the internet to do this but what if you have AutoCAD LT only (as it lacks programming APIs)?

You can use Excels powerful cell commands to convert your layer list to a format that will then be able to create a script file. Below I will go through the steps you need to do to get this to work. (Note this is not my concept but I cannot find the original page where this was proposed).

Firstly create a blank Excel document.

Then place “-LAYER” in the 4th column over.

Now we are ready to input some data into the first three columns. This is in the order, layer name, colour, linetype. Make sure the second column for colour is text only to avoid any true colours being converted into numbers.

One completed we will now enter the following command below the cell with -layer in.

=IF(ISNUMBER(SEARCH(“,”,B2)),”N “& CHAR(34)&TRIM(A2)& CHAR(34)&” C T “&TRIM(B2)&” “& CHAR(34)&TRIM(A2)& CHAR(34)&” LT “&TRIM(C2)&” “& CHAR(34)&TRIM(A2)& CHAR(34),”N “& CHAR(34)&TRIM(A2)& CHAR(34)&” C “&TRIM(B2)&” “& CHAR(34)&TRIM(A2)& CHAR(34)&” LT “&TRIM(C2)&” “& CHAR(34)&TRIM(A2)& CHAR(34))

This creates the magic that is script. (Note the quotes are required for layer names with spaces).

Add layer information down the left and drag the little square in the bottom right of the excel cell to copy this to all cells below.

Once completed, save this file for future reference.

Copy the entire column of D and paste to a new file using paste values only.

Now the file is ready to become a script. Save as Formatted Text (space delimited) PRN file.

You should now have a text file that has the entire script for making your layers you need in it. Two steps to go!

Firstly we are going to rename the extension on the file (if you cannot see extensions follow this). This needs to be renamed from myscript.prn to myscript.scr.

Then open the file and add a return at the very end to create another line. This will terminate the last command and thus end the script.

Finally we load the script into AutoCAD using the command “script“.

Voila, all the layers are now in AutoCAD.

Xerox Printers AutoCAD Transparency Update

Recently we had Xerox printers installed and we could not get the transparancy to play nice with the printer, printing a small strip up the side of the page. We have now found a solution to the problem and after installing PS drivers and changing the settings on the driver page under the PC3 we use to the settings noted below all works fine. Thank you to placidrefining for their solution, which can be found on the following page. Whilst they note that this works with a 7970 printer, we have found that it works with our model as well.


I have posted the images below from that post here for reference.





Hatch ribbon slow to load

So the hatch ribbon is slow to load? I found that the addition of custom hatches on a network path was the cause of the issue. Remove the network related path from the support files and the hatch command speeds up considerably. This seems to be a similar problem to that of the MTEXT problem I have encountered previously.
