Copy/Flip/Attach

[flashawd]

Hello again - been quite some time since I played w/ this program, so having to relearn - so probably many more questions to come. I have half of a circular tube - I had a full circular tube, but screwed it up, so now I have a half. I need to copy/flip/attach it but where do I put it to do that - it sets it right next to it. -Thanks

Try puting it at 0,0,0 with the central seam sitting right on the axis before you do the copy-flip-attach.

Thanks Paul - I'll give it a try.

When I have the problem you describe, it's because I've been careless lining up the points or placing them exactly on the centerline of the grid. It always works right when I do the following:

 

1. Line up all the points of the central spline vertically. The easiest way to do this is:

A. Select the central spline (click on the spline, hit comma key)

B. Click SHOW MANIPULATOR PROPERTIES button on toolbar. This opens a window next to the spline.

C. Select SCALE mode (hit S key)

D. Type "0" (zero) in the window for the scale value of X-axis, hit Enter. This lines up all the points of the spline.

 

2. Select NORMAL mode (hit Esc). Use the mouse to place the selected spline precisely on the grid centerline. Zoom in as much as needed to get it right. (Or you can activate the SNAP TO GRID button.)

 

3. Copy/flip/attach the normal way.

 

Note that if there is anything in the model window that you're not copying, or anything hidden, the c/f/a may not work right. When that happens to me, I either just copy everything and then delete what I don't want, or temporarily Edit>Cut what I don't want and then paste it back in afterwards.
