Map Book Part 3

Now that you have a template created and our map drawing we can start the map book creation. I already covered what to use for the source, model space or the display manager so I’ll pick up on the template. In the template portion of the dialog browse to the dwt file you want to use and select it. Use the drop down list to select the layout to use. This may be where in your template you created layouts of different sizes or pointing to different plotting devices. Either way make sure you select the layout. The next step is selecting the title block “block” to use, again use the drop down list to select the block. Continue with the adjacent arrow block, making sure you select the radio buttons to use them. The Titleblock and arrows are options and you do not need to select them if you have them in your source map already. (either model space or display manager). Also if the blocks are not in the template you have the option to browse to drawings to use for those blocks by clicking on the ellipse icon (icon with 3 dots). However the layout MUST be in the template.

The last thing to set is the scale factor for the layout’s viewport. In the screen capture I marked it as to an approximate scale. Reason for that is because in the next step(s) determines as to what the finish scale will be. You should have an idea of what scale you want your pages to be at.

The tiling scheme section comes next, this is where you tell MAP 3D what area you want to be include in the map book. The first choice is by area. Using this option allows you to window the area you want and Map 3D will determine how many columns & rows it needs based on the template layout viewport size and the scale factor you selected in the template settings. Map will generate a grid on the layer selected allowing you to see how many row/columns it will create or how many pages the map book will have. There is also an option to set an overlap value for the tiles. What the overlap does is overlaps the titles so the finish map page displays items around the edge in the adjoining tiles. Setting this to anything greater than 0 will result in the final viewport scale being off by the amount you set it for. So if you want a scale of 100 and an overlap of 5% then you need to add the 5% to the scale factor in the template settings portion of the settings.

Another choice to use is by number, this option allows you to specify how many rows & columns to use for the map book. You select the upper left corner by picking a point then set the number of columns and rows to create. You also have the overlap option using this method.

The final choice is using a custom area. With this option you need to have polylines created in the source prior. The makegrid.lsp in the sample folder can be used for this if you like. Again be aware of the scale factor and the size of the grid created. If the grid size is not in portion to the viewport size you may end up with a map book that is useless.

Either method you chose allows you to view the tiles before you generate the map book and allows you to go back and make the changes as needed.

The next section allows you to name the pages or layouts a number of different ways. The column and row option allows you to create the names such as A1, A2, B1, B2 etc.

The grid sequential allows names such as 10, 11, 12, 20, 21, 22 etc. The sequential method creates names such as 1, 2, 3, 4 etc. There are a few options on setting the starting number and incrementing that number for all three of these methods. If you work with Township and Ranges then you can name your tiles the same way. The last method of naming the tiles is the data driven names, the names can come from the grid polylines created prior either as attached object data, linked database or any of the other methods you use to attach data to the polylines.

The next section is setting the key map viewport. If you are not using a viewport for a key map you can skip over this section. Here you select what you want in the key map. It can be a linked drawing that has a defined Map Key Source an x-ref drawing or layers in the current map. To me using the layers in the current map is the easiest, unless you are working with the older versions of map books and have the key sources already. To set a layer to use select it in the bottom list and click on the Add Layer to Map Key button. Just keep it simple if you are using a key map, too many layers can be confusing in the end.

The next part allows you to select a legend to use on the pages of the map book. Again if you do not have a legend viewport in your template you can skip this and go with none. The choices are the legend created by the map display manager or a users defined. If you used the display manger to create a legend select that as the option. The user defined is when you created your own legend using the standard objects in AutoCAD such as lines, hatches and text.

The last part to creating the map book is creating the sheet sets. Here the only option you have is to create a new sheet set or a new sub set. If you are just getting started go with the new sheet set option. The sub set option is used in cases where you may already have a sheet set of a large area but in tile number 5 there is a lot of features and you need to create a map book at a different scale to show more details. Here you would create another map book with different settings (scale, tile naming, etc) and append a sub set to the original sheet set under the tile numbered 5. This way you still have one map book but additional pages of tile 5 with details maps of that area.

Now that you have all the settings set click on the Generate button. MAP 3D will create a sheet set, displayed in the map task pane, and layouts for each tile. You can select a page (tile) in the map task pane and right click to zoom to that tile or open that layout and a few other options. If you right click on the map book name at the top of list you can publish to dwf or plotter, rebuilt the set, edit the settings then rebuilt the map book or even check the properties of the map book. 

So now you should know how to create a map book using MAP 3D 2007/2008. Go and try it out, if it does not end up the way you want go back and change a few settings and try again. If you still can not get the hang of it do not save the base drawing and close out and start over.
