Newbie Question

 From: libelle 7 Dec 2014  (1 of 5)
 I'm a new purchaser of MoI. Many years ago, I did 3D modeling with math-based tools like POVRay, and then did some polygonal modeling. I fear that my approach to a particular problem is skewed by that polygonal mindset, so I'm looking for advice on how to accomplish this in MoI. I have an extruded irregular shape that I want to make into something like a bas-relief mountain. For example, I'd like to be able to move the selected vertices down the Z-axis (as shown). I understand that this would require creating new vertices, which is why I can't simply show points and then move them. If I only wanted to do that one corner, it would be trivial to do a boolean operation. But I really want to end up changing the top surface of the extrusion into a terrain-like surface. What's the right way to approach this? Thanks! ___Samuel___

 For tricky mountains Separate Top Face Select Face Show points If Number of Points is not enough Use the hidden function "ShrinkTrimmedSrf" (Press Tab and write it directly ShrinkTrimmedSrf or make a shortcut with this same name of the command ) Add Points (with 2 directions and Symmetry if you want numerous points) Move your points as you want Select the perimeter and make an big extrude Cut the bottom at the start altitude 0 with a simple Line Select the bottom perimeter 0 Planar it Join all = it's a solid! et voilĂ  :) EDITED: 7 Dec 2014 by PILOU
