Extrude shortcomings?

[rami.sjoqvist]

Hi,

New to Xara Xtreme and have some basic questions about the extrude:

1. Seems that if I create an object with no fill (e.g. an empty ellipse), and extrude it, this actually creates a 3D object filled with grey colour, not the pipe-like 3D object I was expecting as the result. Seems really odd that this would not be possible, am I just incompetent?

2. If I extrude something, then change it back into editable object, and then go back into extrusion, I don't go back to the extruded shape I had before. Is this something I do wrong or is it somehow that the SW is not "true 3D" and is not able to cope with this scenario?

Really appreciate any answers on these

Hi welcome to TG

the extrude in xtreme is not a true 3D shape - it is a vector outline with a manipulatable fill that gives a 3D 'effect'

if you convert it to editable shape you 'flatten' that vector outline and fill - if you then go back to the extrude tool you are applying a new extrusion to that flattened shape

Hi,

Thanks for the quick reply, that's what I presumed after experimenting a couple of times. we'll, back to the drawing board

1. The extrude tool only extrudes shapes and not lines. By drawing an ellipse and making it transparent with a thick line will only create an ellipse. to create a 'pipe' you will have to [convert line to shape].

2. Why do you want to convert an extrusion to an 'editable shape'?

If you wish to edit a 3D object turn off the 3D by clicking the 3D button on the infobar. If you click the 3D button on the infobar, it will temporarily remove the extrude. You can then edit the object, and click the 3D button again to reapply the previous extrude - No matter how complex - No additional settings are required.

if you want a pipe, make a circle, add a smaller circle over the top and subtract them. You then have a circular shape with no inside. That can be extruded into a pipe with the extrude tool.

As mentioned earlier it extrudes a shape only - you just have to make the right shape. If you use a font that has a circular "O" then that will extrude as a pipe.

Here is the method I use.

I see that keith beat me to it while I was drawing circles

I think you'd better stick to the convert line to shape approach.
This way you can use different(maybe preset) type of lines,without
adjusting the shape afterwards.

Both methods have advantages, the slicing can be used with different objects to produce some interesting extrudes

OK, so judging from your answers both things actually can be made to work just fine: Editing that extruded object as instructed above worked for me, and not being able to create the pipe was jsut due to my incompetence (the answer, as usual, was obvious whan I now think about it...)

Many thanks!!!

You're very welcome.
