Cross Section Into an assembly

Anonymous — Mon, 03 Apr 2017 23:30:27 GMT

Dear Community,

I to you with what seems to me as a tricky problem. I hope it will be trivial for you to answer this.

I have imported an assembly model from inventor to 3ds Max.

I have selected one of the part of the assembly and added modifiers to apply a cross section view. This is to show the mechanism insides.

I have added slice, Edit Poly and Cap Holes. (note that it wouldn't let me use the modifier Cross Section.

Please have a look at the result in the attached pictures.

The three first picture should let you see that, I think, the geometry is closed.

4th picture shows the result I get where the cap is actually performed on the holes on the wrong face of the solid...

Nothing happens basicaly. No matter what type of cap hole option I select, or Edit poly (Vertex, border, edge...) it wont give me anything correct.

It seems to me this geometry is closed, so I don't get why is it failing to cap.

Would you please have a look and let me know what you think?

Thanks in advance,

Jules

Cross section modifier doesnt work with mesh/polys, it just work on spline to create surface. If you have budget, Scalpel
from Cebas works better. link: https://www.cebas.com/?pid=productinfo&prd_id=6

if you dont have...try this work around

nah.....this workflow is unfeasible for animation....

c'mon you blokes, where's your creativity ? it's very simple...I'll record a video soon...

Hi Masterender,

Thanks for your quick reply. No I do not have the scalpel from Cebas, so I followed the trick.

I have followed your explanation, created a shape and converted it to poly. But it didn't create the surface automaticaly as shown in your picture.

My poly remains desasperately empty. Have you done something else after - right click - Convert to Editable Poly - ?

Should I mentionned that it is for an animation purpose that I have inported this inventor object into 3ds Max.

Thanks in advance,

Peace.

and now you mentioned ...its for animation

Sorry about that. I reckon I should have mentionned it earlier and I thank you for all the explanation you have done so far.

I will try Vusta solution but, disregarding the fact that it is for animation, still the problem remains. I don't understand why can't I close the shape.

Any idea?

Thanks in advance Rendermaster.

coz caps is not smart enough to know how to handle hole within a hole...separate holes are fine even though there are multiples...but if you have a hole within another hole..it doesn't know to do it 'boolean' style...so it simply sees a hole within a hole as 2 holes...so 2 caps which is wrong...

1. create/model the object- just half of it using the center line of the screw location

2. mirror it and attached together

3. add slice modifier

4. add cap holes ( must be on top)

5. animate slice plane...Show end result must be active to see the effect of cap holes)

Good luck

sorry no audio

In case of your model..follow this
