GeoTools NOTES

This file covers compatibility information, late-breaking news, registering info and usage tips for the GeoTools software.

The following topics are discussed:


GeoTools installation:  for AutoCAD 

1. Starting GeoTools: During installation, if you have chosen the AutoCAD profile to use with GeoTools, there is nothing else that you need to do in order to start using GeoTools. Simply start AutoCAD with the chosen user profile and you should be able to start using GeoTools.

2. If you did not do the GeoTools startup configuration during Setup, you will still be able to configure AutoCAD for GeoTools manually. To do this, start the "OPTIONS" command (Tools->Options...) menu and go to the "Files" tab and open the "Support files search path". Click on "Add" and then "Browse", then point to the location where GeoTools has been installed. By default, the installation program would have
installed this under the "C:\Program Files\Four Dimensions\GeoTools17_EN" folder.

3. If you have other third-party applications, there are various ways in which you can manually tailor your GeoTools startup.

a) If you do not already have an existing ACAD.LSP, you can use the ACAD.LSP supplied with GeoTools. This would automatically load GeoTools program and menu as soon as you start AutoCAD. If you wish to be prompted whether to have GeoTools loaded or not, please comment the appropriate commands in the ACAD.LSP file as explained in the 'commented notes' within ACAD.LSP. Once loaded, GeoTools can either be loaded or unloaded using the GT_LOAD and GT_UNLOAD commands respectively.

b) If you already have an existing ACAD.LSP, you can either copy the contents of the GeoTools provided ACAD.LSP to merge with your pre-existing ACAD.LSP or you can load GeoTools separately by first loading the loader program GT_LOAD.LSP and then using either the GT_LOAD or GT_UNLOAD commands to either load or unload GeoTools.

4. Troubleshooting tips:

a. Ensure that the GeoTools folder is ahead of other support folders. When AutoCAD starts acad.lsp from the GeoTools folder should get executed. If there is an acad.lsp in another folder ahead of GeoTools, that would get executed and could possibly be a reason why GeoTools is not intitialized.

b. Ensure that the ACADLSPASDOC system variable is set to 1. If this is set to 0 in your AutoCAD, GeoTools may not initialize
automatically in subsequent drawings opened if you have multiple documents interface turned on and you will need to manually load it in each drawing. The setting of ACADLSPASDOC to 1 ensures that it is loaded in all documents automatically.

Additional Instructions for AutoCAD 2014 and above Installation

When any LISP, ARX, DVB or a .NET dll is about to be loaded in AutoCAD 2014 and above, you will see additional warnings and permission requests unless it is in a pre-determined TRUSTEDPATHS location. This affects the loading of GeoTools as well.

GeoTools uses a main VLX file (GeoTools.VLX)a loader LSP file (GT_Load.lsp) and the doslib ARX files (doslib19/20/21.arx/doslib19/20/21x64.arx) as its main executable components that need to be loaded. Each one of these need user-permission before they can be loaded in 2014. You will see warning messages popping-up seeking your permission and you will have to explicitly grant them by clicking on the Load button each time. 

If you want to avoid clicking on the Load button each time, you need to specify the GeoTools installation folder as a 'trusted folder'. You do this by following the steps outlined below:

  1. Start the OPTIONS command, and select the profile under which your app is running.

  2. Click the Files tab.

  3. Click the [+] to the left of Trusted Locations.

  4. Click the Add button, browse to the folder where you have installed GeoTools, and click Ok.

  5. If you receive an alert (about Read-Only), click [Continue].

  6. Click [OK] to close the Options dialog.


There is another quicker, back-door method to suppress these warnings, and that is by setting the SECURELOAD system variable to 0. This makes AutoCAD run like older versions and no security warnings are issued. Autodesk does not recommend that you defeat the whole purpose of additional security by doing this.


GeoTools for BricsCAD (scroll up for AutoCAD or Click here for AutoCAD)

GeoTools installation:  for BricsCAD

1. Starting GeoTools: Once you have successfully installed GeoTools, start BricsCAD.

Add the GeoTools folder to the BricsCAD support path as shown below:

- Type 'Settings' on the command line or click on 'Settings->Settings..." on the menu.
- Click on the 'Program Options' section.
- Click on the 'Files' item in this section.
- Select the 'Support File Search Path'.
- Click on the [...] button at the right edge of this entry and you will see the list of existing folders which are on the BricsCAD support path.
- Click on 'Add Folder' button and add the GeoTools install folder to the list of existing folders and move this folder to the top of the list.

Now, restart your BricsCAD for the changes to take effect.

2. Troubleshooting tips:

a. If GeoTools is not loading upon starting BricsCAD, it means that the startup LSP file 'on_doc_load.lsp' from the GeoTools folder is not loading. Please check if you have other 'on_doc_load.lsp' files in other folders ahead of the GeoTools folder. If you already have an existing 'on_doc_load.lsp' on your system that you would like to use, you can just add the contents of the GeoTools-supplied 'on_doc_load.lsp' into your existing file.

b. Ensure that the ACADLSPASDOC system variable is set to 1. If this is set to 0, GeoTools may not initialize automatically in subsequent drawings opened and you will need to manually load it in each drawing.

A note about screen resolution

GeoTools makes extensive use of dialog boxes, some of which are wide in size. It is therefore recommended that you use a Windows display screen resolution of 1024x768 or more. If you encounter "Dialog too big to fit the display" error, either increase the resolution or use "Small Fonts" in your display settings.

GeoTools Online help and documentation

GeoTools help is now accesible from within the GeoToools menu by clicking on the "Help..." item.

Registering GeoTools on your computer
