step 1 and 2 the demensions for the rectangle is: 640 x 130mm

Victor,

It took me a few to figure it out also, but what hes doing is extrude/cutting the extra material out of the piston holes at a depth of 160mm from the top of the piston surface.

So pick the "top" of the piston surface and create your sketch there, then look at my picture that Ive attached for a more comprehensive understanding.

Draw all 12 holes like the ones you see in my screenshot and then extrude/cut them to a depth of 160mm from the top of the pistons. Hope this helps you out!!

Brylle, here are those angular dimensions you asked for:

"Brylle
I don't know how far these cylinders should be apart from eachother. Also I dont know if the method I used is correct. mirror the original body and use move/copy command. Need your help buddies. thank you"

here is a picture of the dimension you required:

Thanks for the help. I was able to make the desired output by making another plane coincident with the original body and move it using move/copy command.

here you go, use this as an example to follow what i did.

don't understand step 1 and 6, if you put some dimensions you are the best...

Hey. Can you make a more detailed tutorial about part 12 of the V12 engine tutorials? I cant complete 12 without the dimensions of steps 1,3,7 etc. I tried my own dimensions, but then step 9 did not work!

What are the dimensions for the extrusion in Step 3? And what are the width of the ribs in Step 6?

 
Comments 0

step 9 doesnt work. it results to zero geometry

hello I would like to ask @ what angle I incline the 2 block and how much distance separate them form each others

 
Comments 2

This is what happens when I do step 12. I dont know what is wrong

Brylle,

From what I noticed by looking at your added picture you went to far when drawing your rectangle, ill highlight the area Im talking about in the same picture you posted! I've drawn an orange line where you should have stopped!! Hope it helps!!

The arrow pointing in the direction of the extrusion looks funky also but that just may be the perspective im getting from the screenshot.

Mr. Dana can u please help me with step 5

 
Comments 0

I'm having trouble with step 9. I go to extrude and I'm getting an error "unable to create this feature because it would result in zero-thickness geometry". I think it's something to do with direction 2 because I can get it to extrude to the body just fine but it wont extrude to the surface. Any help would be greatly appreciated. Thanks!

Hello could someone please help me for part 14, i cant get the sketch right. its the crank connection part after making the cylinder.
Thank you :)

What is the dimensions in the first Picture ??, i am using inventor, and need the diamensions of the rectangle ?

Olá, gostaria de saber qual a distancia entre os dois corpos no passo 4, grato.

after a lot of try and error
I made it :)

What i don't understand is that when i do step 7, the width of the ribs blocks a portion of the cylinders! How is the piston going to fit inside the cylinder when there is a portion of each rib "in the way"?

my file, if you need, I am not sure about dimensions, I made by solidworks 2010

Hey, could someone help me out with this model on autocad inventor... sorta stuck on step 8

Does anyone nows how to make step 5 in catia?

Step 4

mirror all bodies with using right plane

Problem is that i dont have any bodies
only cut extrude, boss extrude, sketches, mirrors etc on the left side. They can be selected but doesn't make a mirrored object like on the left.

So what should we do before we mirror????

how can I get the dimensions sheet for engine parts?
please help me to find the dimensions

I checked the proportions between his sketch from the bottom view later on, these seem like more accurate dimensions for Step 1.
