Hello everyone, I am trying to split a blade for making fiber mould of it but as the blade is curved I am not able to split it using the split command ! I am attaching the 3D model file below for reference. [IMG_5635] [IMG_5634] blade-01 frp.shapr (1.6 MB)

In the olden days of Shapr, we had to draw a split, duplicate the part and loft the split. Before the split tool that is. Splitting a body - #2 by TigerMike

Yes I know it but the blade Is curved so I am not able to cut it in half like the other part ! Even if I draw the sketch and try to extrude cut it , the command will cut it in a straight path !

Then you will need to get creative and make the 2 bodies that will allow you to make the cut you want. Which will also serve as a mold or a negative of the mold? You are in the “Tool and Die makers” realm now. I worked with one. I designed and built the electrical automation for the “Little Titan” …

I believe you can use a curved edge with Split Body. Create a dummy curved body that is positioned next to and where you’d like the split. Do the split and delete the dummy body. (And thanks @Oregonerd for going down memory lane.)

Hi Mike! The problem with this body, that is twisted and bended… For this reason, I think that every profile should have a section, to create a twisted surface body for subtraction.

Yes, this is a complex surface to split. I was showing that in addition to splitting via a flat plane or surface, one could do the split via a curved surface. And yes, it doesn’t work on a complex surface.

If you can loft the highlighted crossections, you can split with subtract.
Would be nice use the trailing edge as rail.
