So another minor complain on 3dmax’s UI. Its sort of very minor, and in essence is just a tiny thing, but still I personally think it could, and I think should be improved. So it’s about camera (not exactly camera, just viewport) position when you are modeling. So I guess many of us, max users are using “zoom to selected” viewport tool. I use it a lot, and especially when modeling. So the situation is this. One is modeling something, and selects a couple of vertexes, which happen to be in same position. Now we can’t really see anything cos now we look at whole model. so we hit zoom to selected, and bam most likely we see.. nothing. Or just some part of our object, which has suddenly lost its shape. Its viewport clipping I guess. The zoom tool zoomed so close to selected vertexes, that max decided it’s too close and just clipped the model. Or that’s what I think that happened. Look at the pictures, or try it yourself. Not sure if it is exactly what happens, but it sure looks so. Why does max do this?

just an object

just an object

(usually this happens when we model say a character, or whatever, and we work only on one half of the model. Other half we minor, and later on we want to weld vertexes which duplicate in the original and mirrored object.. at least that is one of situation where this occurs..)

So what do we do? just scroll back a bit, bam, the model is back, and we are close to our selected elements to work with. But, if you are unexperienced, u might go … Ouch, what happened??? or just scroll back, like you did 1 million times. But can’t we make a tweak in viewport camera positioning and zoom to selected tool’s code, so it doesn’t go to such extremes where model gets clipped? Anyone? So it’s just another small complain. Yes, I know there is million other things that are more important to improve. And this is just a tiny annoyance.. but if it would be just a couple of lines of code, might be it would be worth while writing them down? sins I suppose it should be quite straight forward thing, it’s not like one has to write Lagoa for max or anything like that… (Yes Lagoa would be cooler to get… :) Am I right? am I wrong?

As many of you I do enjoy working with an “extrude along spline” tool.
It makes your modeling so much faster in some cases, and it has
flexibility to achieve various results fast. I found it very good when my
task is not very constrained, when I work with something that I can change and create at my will.
But Some time ago I needed to do something more precise. To be exact i had to
do some lines on a sphere surface. I did remembered nice tool we have in NURBs arsenal which is called “create cv  spline on surface”. Now that i had my splines on a surface i needed to use them as splines for extrusion in my model.  And then I had some troubles with extrude along spline tool.  It just doesn’t seem to actually follow given curve, or to be more precise, the result is same as the curve, but its orientation is all wrong.
And then I had to find how to fix it. So if any of you happen to have same problem
here are some screen shots with a problem and its solution.

So we select faces and go to extrude along spline, and we choose our spline.

 

aligning

aligning

“Align
Aligns the extrusion with the face normal, which, in most cases, makes it perpendicular to the extruded polygon(s). When turned off (the default), the extrusion is oriented the same as the spline. To Face Normal, the extrusion does not follow the original orientation of the spline  it’s reoriented to match the face normals, or averaged normals for contiguous selections. The Rotation option is available only when Align To Face Normal is on.”  description from 3dmax help file.

“Rotation
Sets the rotation of the extrusion. Available only when Align To Face Normal is on. Default=0. Range=-360 to 360.” again, from 3dmaxs help.

So here we

select the vertex which is closest to extruded polygon so we can make it “first”

wuala!

wuala!

 

 

 

 

 

 

 

 

 

 

 

So we have it. Now our extrusion actually follows given spline. This seems to solve my problem. Hoope it helps you too.
