Hi Mike

Extruded surface as you said - works a treat

Thanks

The one thing to be aware of is that the original surface still sticks around after the extrude, just like when you extrude curves the original curves stay in place.

But with the surface it is more difficult to see the original surface since it exactly overlaps with the resulting object. You may want to hit delete after you do the extrusion to remove it.

clegg/michael. I dont seem to grasp all in your last 4 related posts--could you help, maybe graphically, explain please?
(Probably me having another "brian" day!)

Hi Brian, see if this helps:

The most basic way of using extrude (which I think you are already familiar with), is to select a curve like this:



Which then after extrusion will result in an object like this:



However, if the curve is not a flat planar curve, it won't become automatically capped at the top and bottom when doing the extrude.

There is another way that you can use extrude instead of using a curve as the initial object. It is also supported to use a surface as the initial object, like this:



After extruding, with that surface selected as the input, this object will be created:




That type of extrusion will always have a cap even if the starting surface was not planar - this is because MoI is able to make a copy of the starting surface to the other end to construct the cap in this case.

Does that make sense?

Thanks Michael--I still can not get the working connection for doing the type though?

I tried doing a sweep of a horizontal/vertical curve to create a cutting surface as in attachments. I think this is not what is meant though either.

Hi Brian, it would go something like this:

Start with text that are curve objects (not solids), flat on a plane:



Now a curved surface over top of them:



Then select the surface and run Edit/Trim - pick the curves as the cutting objects and at the "select pieces to remove" prompt, just push "Done" or right-click to keep all the pieces. This will cause the surface to be sliced up into multiple different surfaces.

Select the inside surface pieces:



Then those can be extruded just like I was showing in that previous post:

seems there was yet a thread about that some times ago :)

Thanks Michael---I was def not thinking like that!
Added to my Help file folder.

I hope this shows my thick scull is learning!

And!

Fine kangaroo!
