 This assumes that you have a 90 degree routed sample.  You'll have to make tweaks but nothing major for something not of that nature.

-As a workaround save and close.  Open up a text editor and find the layer you just inserted.  Make it look something like this:
+Create a new layer to store the image.  File→import and select the image you want.  You should now be able to show/hide that image as a layer.  I suggest also locking it so that you don't move it around.  Go fo file → Document preferences and hit "fit size to selection".  The document will not be the size of this image.
-  <g
+Repeat for additional layers.  Align the additional layers by setting transparency to 50% on the layer selection box so that you can make a reasonable match.

 Start by creating and selecting a new layer.  If you have a top metal image you might want to create "m1' or "metal".

 ===== Large / complex polygons =====
-Multiple polygons can be combined together.  This can help in drawing very large polygons without having to do everything in one go.  Select both polygons and then click Path => Union.  You may want to delete some of the extra points it creates.  However, if you are careful with how you create your shapes you shouldn't be generating extra points.

 I recommend against forming complex polygons (ex: a doughnut), in part because JSSim can't currently handle them.  If you don't care about JSSim this is probably not a big deal.
+====== Issues ======
+Inkscape 0.47 and perhaps some other version has a bug where your won't get 90 degree snap on the last point.  See [[https://bugs.launchpad.net/inkscape/+bug/522335|https://bugs.launchpad.net/inkscape/+bug/522335]] I'm currently using 0.48.3.1 which seems to have this bug fixed.
