morph question

Paopao — Wed, 24 May 2023 17:21:04 GMT

Hi guys, I need to make a solid as in the first pic. How do I go about it? I thought to use orth and revolve around the central axis but I can't exactkly detect it somehow. I use the morph revolution around an axis but I am not able to set the axis. Any help? The solid can be straigh in its uppper part.

Thanks PP

Here is a clip that explains it:

Hello Pao Pao,

To start, draw one of the desired profiles of the form in the elevation view (this can be done with line work). Start by drawing one arc (the outer arc for example) and offset a copy of this arc or simply draw a second smaller arc. Finally join the two arcs together using two lines (see image below).

Next, select the morph tool from the tool bar and hold down space bar (magic wand) and left click anywhere inside the profile you have drawn. You should end up with something like this (see image below).

Next, select this morph in the 3D view and click anywhere on its face. This will bring up the pet palette, select the push pull option and extrude the profile to the desired length (see image below).

Finally, change the arc radius of the top and bottom arcs on one of the faces of the morph by clicking on its edges (see image below). Note that this can also be done in the elevation view.

Hope this helps.

Jarrod,

If you look at the geometry from the side, you will see that the line connecting the two end profiles is not a straight line, but a curve. This is why I think the Revolve method gives a more accurate result.

Than you guys, I thinbk Laszlo is right as the height of the back part of the object needs to be smaller as it needs to fit under the tile of the one in front.
Thank you so much for both inputs!
