Extrude Not Creating a Closed 3D object.

[inujuju]

So I am currently working on a playground development for a school project where we have to build a 3D playground based off of autocad drawing, modles, etc.

Below is a picture of a "crab see-saw" that I have in my park, and I am having trouble making it 3D. I have tried using "extrude", but, while it streches the drawing into 3D, only the crab's claws become a solid object. The crab's body remains "open".

 

-> Normal Drawing

-> Extruded Drawing

 

The steps I take to extude it are:

1. Select extrude command

2. Select entire drawing

3. Click top of crab body for designated height

4. Type in 7 (units) as the strech command

5. Press enter

 

All the lines for the crab body are connecterd and I just can't figure out why it isn't working. My teacher is also baffled. It would be my pleasure if you could give me advise on how to fix this.

It would easier to check if you could post the file.

 

I will move this to the AutoCAD 3D Modelling & Rendering Forum for you.

Thank you very much.

How would I go about posteing the file? Is there a way to link it up here or should I upload it on a downloading site like MegaUpload or MediaFire?

Click the "Go Advanced" Button at the bottom of the reply box. Then select Manage Attachments.

Thanks!

The claws are a solid, as you said, the rest is a surface (which you did not expect).

 

Try using the Press/Pull command. That should work.

 

Note: you may have a problem in a couple of areas due to all the little line segments you used. Not a good habit to develop.

Crab cakes anyone?
