unable to revolve selected item...help

[gogolwriter]

So I have solved the revolve be recreating the profile using the spline command - method - fix.

The problem as some of you have suggested is due to so many vertex points....due to my spline command having CV as a default. By using the "fix" approach to spline.

So the problem is due to my initial method of creation.

Self teaching myself autocad no doubt will lead to a number of wrong paths in order to find my way. Thanks for all your suggestions!

You used the spline command. Why? You couldn't create the profile without using spline? Was this just an experiment?

What is the object supposed to be?

 

Was the object larger initially then scaled down?

 

When you finished creating your 3D model what was the file size of your drawing?

 

I looked at your drawing. Units are set at decimal inches. The object measures roughly 0.85 x 5 yet it has 7505 objects. I can design a 3,000 gallon reactor with all nozzles and manways in 3D and come under that number. When I ran the OVERKILL command on it AutoCAD reported back there were 869 overlapping objects (which still leaves you with 6636 objects). I'd suggest you re-evaluate your methodology when doing something like this otherwise your 3D drawings will be unnecessarily huge as far as file size goes.

Use primitive geometry like arcs and lines.

 

Lines should never be created as splines.

More points (if a spline is needed) does not equate to a better curve, in fact, just the opposite is true.

 

Work close to the 0,0,0 origin.

The initial jpeg photo I converted to a dwg and at first thought to copy the outline of the photo with arcs and lines, but found the outline to complex. So I gave the spline command a go...which made it easy to copy the outline...but then I ran into trouble because I used the cv method of spline. I then after input from the forum, that I needed to reduce the number of vertex....discovered that spline had another approach "fix" and so I use it and was able to revolve the profile.

Yes this was a experiment for the most part and spline was a new tool that none of the two autocad teaching books, that I went through never covered (one book covered basics with building a cabin as the main teaching example, and the other covering different approaches to 3d modeling)
