Note “Double” on this page >> http://docs.pixologic.com/reference-guide/tool/zsphere/display-properties/

you can try “mirror and weld” along the proper axis, in the geometry palette.

I would position it so that you can use mirror and weld. I’m assuming you don’t want the whole thing, so one you’ve mirrored it, dynamesh it and get all the detail back and then cut it in half using slice curve.

There’s no need to use Mirror And Weld. Hold Ctrl+Shift and select the TrimRect brush, then (still holding Ctrl+Shift) drag a rectangle so that it just clips the back of your model. This will give a flat back.

Edit: Actually, that would only work if it was just the back that was needed but I see you also need the base. So first Mirror And Weld along the back line. Then trim the base as I describe above, followed by the back.

It’s very useful is to say how you arrived at that stage of the process as well…

Marcus, would that not only work if you had geometry to clip? Didn’t think it would work to fill a hole. Off to try it though.

Lot’s of answers, any feedback on having tried any of them Marwa?

Gordon,
You need to trim off a little geometry but then you generally will want to do that to tidy the edge. If you can’t do that then using Mirror And Weld twice will be necessary. The TrimRect brush is the one to use as it fills the hole rather than displacing the geometry (as the ClipRect brush does).

The images show the method. I used the DemoHead and cut off a deleted the back geometry. The first image shows that the TrimRect Brush can’t be used when the back and base both need closing. The second image shows the method to use.

Cool thanks. Every day is a school day :slight_smile:

So trim,/clip rect fill, but trim/clip curve don’t? Is that right?

The Clip type brush (ClipCurve, ClipREct, ClipCircle, etc.) squashes the existing geometry. The Trim type (TrimCurve, TrimRect, TrimCircle, etc.) removes the geometry and then fill the hole. See here:

http://docs.pixologic.com/user-guide/3d-modeling/hard-surface/clip-brushes/trim-curve/

Ah, I’ve had problems using the Trim Curve as it seems to act just like the Slice Curve for me often. Time for some investigation. Thanks for your help here.

thanks a lot guys
i tried to use trim but i had prob also with this … seems that i’ve to use 3d max …to close this surface
and iam still trying to find out more about this …
and about how i did the model
i used ( structure from motion) photogrammetry technique … to build the model using photoscan .

You mean the technique Marcus described doesn’t work?

well i mean that cuz it’s 2 surfaces missing … i cant mange it using trim but in fact didn’t use the mirror until now …

But that’s the point. You can’t do it with just the trim brush. Mirror and weld first, then use trim brush on the but that’s still open. Then you can get rid of the extra.

yes " gordon " ^^
in fact u are right Mirror and weld first … it works in this way … thanks a loooooooooooooooooooooooooot :slight_smile:
