Pressnpull,extrude command need some help

[miroslav_s]

Hello,

 

I need help with “drilling” the hole through the ”engine” so that hole appears all the waydown to the spark plugs. I put 6 spark plugs inside the engine, if you changeto X ray for example you will see those spark plugs inside the engine. I triedpressnpull, extrude but could not do it. Can somebody please tell me the rightway. I placed on circle right above the engine as you can see and this circlerepresent the dimension of the hole. I have also drawn a circle under the sparkplug and this circle represent where the hole should end. I hope you dounderstand what I want and please tell me how to do this. Sorry for the bad paint-drawing J(http://prntscr.com/2pj4xp)

Also oneother question:

I was planning then to pull six cables on the engine and those cables should follow thesurface of this engine, like this: http://prntscr.com/2pj5l2. Now, the problem isn´t when Idraw lines on plane surface, that´s easy but when I get to the part of theengine when the surface is not plane how do I make the lineto follow that “fillet” that I made before? Oh my god, hope you understood whatI was trying to say J

Here is the drawing: https://dl.dropboxusercontent.com/u/8906158/need%20help.dwg

 

Thank you in advance for all the help.

Best regards ,

Miro

It would be better if you will post the images here.

 

To create a hole with a certain length you may either:

• use EXTRUDE command with a proper UCS,
  
• draw the sections (circles) at both ends and use LOFT to build a solide between them,
  
• draw a CYLINDER and place it in desired pozition.
  

For wires I suggest you to use either EXTRUDE or SWEEP along a path (use a SPLINE for a better look).

I reoriented the UCS and extruded the holes. Here's a closeup. BTW...the visual style is X-Ray.

 

 

Would the bottom of the hole necessarily be flat? Not sure if that makes any difference to you or not.

Well first of all thank you again Remark, but of course I have one or two or more questions for you. so:

 

You wrote:" I reoriented the UCS and extruded the holes", when you say reoriented do you mean that you put your UCS to on the circle that you used for extrude command later? For me it is not the problem to extrude, the problem is that I don´t get the hole when I use extrude command if you know what I mean.

The bottom of the hole can be flat that is no problem at all. Please explain where you put your UCS because that must be my problem. Extrude,presspull command are not strange to me cause I use them alot but in this case I am stuck!

Thanks again ReMark for having the time to help.

Best regards,

I aligned my UCS with the edge of the sparkplug although I guess you could use the circle. I used the 3 point option. Just indicate the direction of X, Y, and Z and you are all set to go.

 

BTW....your circle is not completely below the end of the sparkplug. The electrode extends into the engine block.

I haven't opened the file (I don't like going to file sharing sites), but that looks like a clearance hole - be sure to make the diameter large enough that wrench socket will fit in the hole.

For the threaded hole - be sure to use tap drill size, not thread OD.

It worked!

Thank you!
