erroe circular matrix loft removed

[Stefal639]

boys there is a tremendous problem in my catia(v5r20).
I was in the modeling, approximated of lazy and conical wheel, I had found myself well with the loft, but to make a quarry for the fat between a tooth and another I had to ingegnate with the loft removed, since now the pinion was completely designed (nothing that, but cmq a great break to respect the original measures). I design the two sketches and make the loft removed, and so far everything ok, then I go to make the circular matrix and...and I find that the matrix has a huge bug...practically the circular matrix command is respected, but instead of making a removal of material (so repeat x times the loft removed) makes me x times the classic loft, then bringing me material:angry:
I now have this copy of catia that was given to me by the professor under license for a year, and I can not miss to change to the r19 that I had downloaded to try it this summer, because all the drawings (about 20 other details) are made with the r20 and are not opened from the r19.
do you know any remedy for this huge problem? :wink:
I am desperate:frown:

here is an example that is + "visible"
I made a disc and a loft removed between a 5 mm offset plane from the upper face (short a circle) and the lower face of the cylinder (short an ellipse)as you can see replicate the loft function and not the loft function removed!

Bye.
try this: move the loft and its matrix into a new body after which you perform the Boolean operation. you can choose to make a positive leotard using the loft or negative using the loft removed and depending on the type of body you have created you will use the specific boolean.
greetings

Nothing to do... When I try to do the Boolean operation I don't know why, but crash catia with a "denomination" error...I let it lose...I do everything that doesn't work with the r19 except in iges and the open with the r20...it's a bit sluggish especially if I have to correct some pieces.
