Linear Stroking on simple terrain model

Hi

Im creating simple four sided terrain models for the use in borrow pit mine plans. The automatically generated triangles are from diagonal to diagonal and only results in the creation of two triangles.

This affects the contours of the platform in a sense that they are not uniform. I would like to increase the number of triangles and by doing so smooth out the contours.

I have tried creating the terrain model by reducing the max triangle length so it should be able to solve from diagonal to diagonal but that doesn't seem to affect the creation method. A work around could be to create a complex element with a vertices every 1m then force the triangulation between the vertices. This however is tedious method and im not sure how i could quickly do this either.

I think what im looking for is a feature similar to that of linear stroking in order to force the triangles to solve at a more regular interval other than just at vertices. So if anyone has another method please let me know.

Thanks
