Hi all,
I am trying to create a ring geometry in 3DEC 7. I am deleting the inner cylinder from an outer cylinder but the resulting deleted block geometry is not smooth and has some blocks left. I have tried deleting by range position grouping and by joint set which has resulted in many new joints. Kindly suggest how to get a smoother geometry.
The geometry of the inner cylinder isn’t actually contained within your model currently, you are just using the block delete command with a range argument that will select blocks with centroids within that cylinder range. Hence blocks with centroids outside of that range are not currently being deleted, and therefore not leaving a cylindrical profile.
To get a “smooth” inner cylinder, you either need to have that inner cylinder in your geometry before you generate the blocks, or undertake block cuts to form it.
I would suggest reading the documentation sections on model generation and generating block assemblies.
