When trying to save a detail, you saw the following error message:
No valid detail title block found.
The name of the Detail Template boundary layer has most likely been changed.
This layer absolutely needs to be named L-DETL-BRDR-NPLT. If its name changes, Land F/X will be unable to recognize Detail Templates when you place them – hence, the error message.
We've followed CAD layer naming standards closely in naming the layers that pertain to our software. Many of our default layers need to maintain their original names for Land F/X to function correctly. For this reason, you should be extremely careful when editing layer names. In fact, we really only added this ability in order to make our software fully customizable; in most cases, we don't recommend changing the names of layers.
To fix this issue, you'll first need to figure out the name of the layer assigned to Detail Template borders.
Place a new Detail Template in your drawing.
Select the border of the template, and open the Properties panel by typing Prop in the Command line. Then note the Layer name as pictured below.
Now open the General Preferences. In the Layers section, scroll to and select the layer you found in the Properties panel.
For example, let's say the name of the layer has been changed to L-DETL-BORDER. Scroll to and select this layer. Then click Edit.
The Edit Layer dialog box will open.
Once you've found the layer with Detail template boundary in its description (see the image to the left), change that layer's name back to L-DETL-BRDR-NPLT.
Click OK to save your changes.
Back in the General Preferences, verify that the layer is now correctly named L-DETL-BRDR-NPLT.
Click OK to save the change.
You should now be able to save details without an issue.
