I have been using NHT since ACAD2000 up to and including ACAD2008. Because NHT was designed for older autocad versions (the last NHT was, I believe, dated 1996) and it is DOS based and not Windows based, it's compatibility with the newer versions is a little tricky. But I can load in all the modules. Here's what I do (file names and sub-directory names are as per my NHT file structure and may differ somewhat from yours):

 

In Autocad, under Tools/Load Application,

 

Find your NHT directory and load in the following files:

dos_nht4.lsp

dosnht4c.lsp

loadnht4.lsp

nht4.lsp

 

Then go to the individual module sub-folder and load in the two lsp files you see. In your case go to the PI directory and load in:

dos_pipe.lsp

nhtpipe.lsp

 

That should get the piping section of NHT loaded. You will have to do this every time you start autocad. I have not tried putting these files in startup suite as I don't need them all the time. I am not sure if all these files need to be loaded, but this is the combination I found that works and don't want to mess with it.

 

There should be a toolbar for NHT that, on my screen anyway, has question marks for the buttons because there are no bitmaps assigned to them and I didn't bother fixing it because I use NHT intermittently.

 

Hope this helps.

I've been using NHT for quite a while by changing a line in the LoadNHT4.lsp routine to reflect what version of windows i'm running.

Unfortunatly, I haven't been able to figure out what the secret code word is to get it to run using windows XP.

Anyone able to help me out?

Create new lisp file XPloadNHT.lsp

 

(setq nht4pre "C:/NHT4")

(load (strcat nht4pre "NHT4"))

(load (strcat nht4pre "fa/fastener"))

(load (strcat nht4pre "st/nhtsteel"))

(load (strcat nht4pre "pi/nhtpipe"))

(load (strcat nht4pre "we/nhtweld"))

 

Top Line should indicate NHT path

 

In AutoCAD add to Application Load Startup Suite:

 

XPloadNHT.lsp

NHT4.lsp
