Since "a picture paints a thousand words", I attach a pdf showing the results of the execution of the code. Are these bugs or... ? Best Wishes Keith On 06/01/2022 15:57, Keith McKay wrote:

Hi

In the code below you will see that I have created a closed path and performed scaling, and shading on the path with lmt_shade [ ]. I have noticed a few features which may or may not be bugs depending on whether scaled is applied to the path within the square brackets or outside.

1) Applying scaled to the path within the square brackets and incrementing the radius key I can see the shaded areas changing, however the first two shapes show incorrect scaling and have ragged edges.

2) When scaled is applied outside the square brackets all shapes are the same size and no ragged edges, however the shading is not showing correctly with increasing radius.

Am I missing something?
