Spatial Manager™ for AutoCAD - FAQs: Background Maps ("Standard" and "Professional" editions only)

Introduction

• Objective of this section
  • To learn how to show image Maps in the Background of the drawings, which can enhance their quality as well as make them more understandable

• Topics in this section
  • Select 'Background Maps' models
  • Show / Hide 'Background Maps'
  • Reference for 'Background Maps'
  • Some other tools such as "Refresh" or Regen the 'Background Map' under special conditions

How can I display a 'Background Map' in the drawing?

You can select an image map model to show as 'Background Map' in the drawing by executing the 'SPMBGMAPSHOW' command of Spatial Manager™ for AutoCAD, which you will find in the "Spatial Manager" AutoCAD ribbon. This will open the "Background Map" window to let you select a model from the Maps list. You can find the list arranged using different Tabs for the different Provider (OpenStreetMap, Mapbox, etc.). The image of the 'Background Ma'p is automatically adapted to the current drawing view and it will be automatically fitted when the drawing view changes (zoom, pan, etc.)

To change the image model map for the 'Background Map', you can execute again the 'SPMBGMAPSHOW' command. The "Background Map" window will display emphasized the current image map model, which you can keep by clicking on the "OK" button. Click on another model if you want to change to this model

How can I hide the 'Background Map' in the drawing?

You can hide the 'Background Map' that is shown in the drawing by executing the 'SPMBGMAPHIDE' command of Spatial Manager™ for AutoCAD, which you will find in the "Spatial Manager" ribbon, toolbar or drop-down menu

If you want to display the 'Background Map' again, you need to execute the 'SPMBGMAPSHOW' command again

Need to have some reference in the drawing to use the 'Background Maps'?

If the drawing is not empty when 'SPMBGMAPSHOW' is executed, it is necessary that the drawing has been assigned a Coordinate Reference System (CRS) in order that the application "knows how-to" adjust the image of the 'Background Map'. If this is not the case, you can assign a CRS to the drawing (and modify it) using the command 'SPMSETCRS' of Spatial Manager™ for AutoCAD. By executing this command you will access the CRS catalog of the application where you can:

• Filter the CRSs by type (Geocentric, Projected, etc.)
• Choose a CRS by clicking on its row in the table
• Search CRSs by typing the search criteria in the "Search" box. You can type here as many words as you like separated by blanks. The application will find all the rows including all these words in a column of the table

If the drawing is empty when 'SPMBGMAPSHOW' is executed, Spatial Manager™ for AutoCAD will assign the generic "WGS84 / Pseudo-Mercator" (EPSG 3857) CRS to the drawing. This is an approximate projected CRS valid for most areas of the earth which lets you start a drawing with a 'Background Map' as a basic reference

Is there any special condition to use the 'Background Maps'?

Some image maps providers included in Spatial Manager™ for AutoCAD may require special terms of use for the users of their maps. You can configure any special setting needed to load the maps of such providers through the application Options ('SPMOPTIONS'). You can change the settings as often as desired. You can even insert blank values to reset the values of these settings

You can also configure and save settings the first time you try to use ('SPMBGMAPSHOW') a 'Background Map' that needs a special configuration

Is there any way "to repair" the image of the 'Background Map'?

There may be situations where the image of the 'Background Map' in the drawing shows up as broken, incomplete, etc. Most of these issues can be solved through a regeneration ('REGEN') of the drawing. However, some problems may appear which require you "to refresh" the image using the 'SPMBGMAPREFRESH' command of Spatial Manager™ for AutoCAD

How can I improve the performance of the 'Background Maps'?

If you find bugs or decreases in the performance of Spatial Manager™ for AutoCAD when showing 'Background Maps', you can try to turn off the AutoCAD 'Hardware Acceleration'. This setting may be essential when your system incorporates some specific graphic cards

'Hardware Acceleration' switch in AutoCAD 2016. This setting may be different in other AutoCAD versions

Can I use the 'Background Maps' and the 'Online Maps' of AutoCAD?

AutoCAD includes from the version 2014 the option to display 'Online Maps', in a similar way to Spatial Manager™ for AutoCAD when showing 'Background Maps'. The technologies used in both cases are slightly different. The Spatial Manager™ for AutoCAD 'Background Maps' can be selected from many more map providers and the application of these Maps in the drawings will be easier to use for most basic and medium users. Using the 'Background Maps' of Spatial Manager™ for AutoCAD won't prevent you from also working with the AutoCAD 'Online Maps'. Use one or the other, whichever you prefer at any given time

AutoCAD includes a Ribbon Tab named 'Geolocation' to control the 'Online Maps', as well as any other available AutoCAD Geographic tool

This Tab is automatically loaded and displayed every time you access a Geographic command in a contextual mode (quite annoying behavior, indeed). When you install Spatial Manager™ for AutoCAD this feature is disabled by default, but you can:

• Open the Tab only when you need it through the right-click menu of the AutoCAD Ribbon:

• Or, restore the AutoCAD default behavior in the Spatial Manager™ for AutoCAD Options:
