DTM problems...

Recommended Posts

Hello -

I am having a problem with the DTM tool in VWArchitect/Landmark


Basically, I created a Site model using 3D loci - it worked quickly and

beautifully. For reasons that I won't go into, I decided to delete the

DTM and create a new one. I used the procedure described in the

Landmark manual - it gives you three 'warning' messages prior to

actually deleting the DTM.

I then tried to create another DTM, but the software seems to think

there is still one there (I think). At this point, when I use the

'Sitework>Site Model' command, the 'Source Layer' and 'Destination

Layer' pull-down menus are grayed out, and the check boxes below

them say 'update' instead of 'create' proposed/existing site model.

I then deleted the site model symbols in the, DTM classes, etc. to no


What's going on?

Hi Doug,

Try copying the data to a new file, and running it from there. Sometimes certain sequences can leave parts of the DTM system which confuses the commands.

Let me know how you make out.

Thanks for your response. I had tried your method and it does indeed work. The problem is that I don't want to have to do this every time I run into this issue.

In the case of the project I am currently working on, There are about 20 layers containing non-DTM information. As you know, it is a total pain to copy them over to a new file layer by layer.

It seems to me that this should be submitted to the Bug List.

Thanks again,
