We are going to install some silos hear at my company and we need a drawing for the township. We have an airport near by and I would like to provide them with a close respresentaion of what it will look like compared to the building. I am looking for some silos that I may use in this drawing. The representation does not need to be exact. Any direction would be helpfull.

you could draw a cylinder 12 inches in diameter and 10" tall with 0,0,0 as it's base point, add a cone on top also with a 12 inch diameter and 2" tall... it's base point would be 0,0,10 --

block it and call it silo using 0,0,0 as it's base point. --

if you needed a silo 15 feet in diameter and 30 feet tall... just insert your silo block with an X and Y scale of 15 and a Z scale of 30. --

I'm actually quite unfamiliar with normal silo dimensions and this might work better using a cylinder of 8 or 9 inches and a cone of 4 or 3 inches. the key is to make the height and diameter 1'... that way the dimensions in feet are always the scale factor. so if your silo were 10 feet in diameter and 50 feet high... the scale factors become X and Y of 10 and Z of 50.

I'd suggest a simpler method of creating your

silo. Draw a simply polyline of the cross section and then rotate it,

creating the solid. That simplifies making the cylinder and then the top

using various union and subtraction commands.

That would be more simple for one silo... especially if the one silo needed to be accurately depicted. When I hear the word "some" I don't know if that means two or two hundred... I try to assume the worse case scenario... the two hundred is unlikely but who am i to guess at how many... with the version I describe you draw it once... and insert it as many times as you'd like over several jobs even. -- I'm a revolve a profile kinda guy like yourself... but have to admit that the cylinder/cone option I described is faster and more simple when it becomes a repeated process... what do you think?

I was thinking that the revolved solid would

be made into a 3d block, which can be easily copied and inserted into a drawing

many times. And if he really wanted he could add the silo as an MVpart in

ABS and then use it as many times as he wanted. If numerous different

sizes were needed I'd think that a parametric part would be perfect for a simple

shape like a silo....just my thinking....

true... true... I was thinking that you were suggesting drawing a new profile each time you had a new silo. Okay.. i'll buy your method.

A better way:

Open content builder, make a parametric part.

Create a top work plane. Add Geometry - two lines with the end points

connected. Add two round profiles to the top plane - one big, one very

small. Right click on the big profile (on the tree) and add a path - click

the first line - the cylindrical section! Navigate the tree to the

modifiers branch - right click - add path. Choose the second line, the

small profile, then the big profile - the cone section!. If you get it

backwards - undo - repeat but pick the large profile first. Dimension

the height of the cylinder and the cone. Also, dimension the diameters of

the profiles. Make sure you use the add dimension right clicks of

content builder - not AutoCAD or AEC dimensions.

If you want to add a manhole or side mounted

connectors, you will need to add lines perpendicular to the silo's axis

at a dimensioned distance and extrude profiles along

them.

at a dimensioned distance and extrude profiles along

them.

Add connectors. Now, go into size parameters,

configuration, and change the values for the heights and diameters to

lists. Switch to values - enter your list of sizes for each

parameter. Make the second profile very small to approximate a

cone.

Generate the bitmap - and you are done - a

Once you are familiar with Content Builder it

really is that easy - no kidding! Sure beats scaling

blocks...
