How do I extrude an imported svg along the z axis without clipping the original shapes? I have imported an svg and I am using the tutorials here: http://spolearninglab.com/curriculum/software/3d_modeling/blender/blender_02.html

and here:

It seems pretty straightforward, and I even got it to work with one shape, but other shapes are truncated or clipped in strange ways.

For instance, this original svg is simple:



But then when I import it into blender using the above method I get this:



Another one I have is even more strange.  Original:



But then in blender using import svg and extrusion:



Would love to know what I am doing wrong here!  I have gone over both articles several times and not really sure what else to try.  

Thanks!

EDIT:  Here are the svg files for reference -

This sort of thing can happen when your object has a very extreme scale.

To fix it, apply the scale with &#9096; CtrlA> Apply Scale.



When you scale an object in object mode the mesh data is not changed, but it will be distorted according to the scale in a non-destructive way (like a modifier). Since your object was scaled up by such a huge amount, it caused some distortion; probably due to precision error.
