Hi apophis,

> is it possible to set an offset value for rail or profile in sweep?

Yes, but not directly inside of the sweep function itself - just use the Construct / Offset command on the profile or rail before you do the sweep, and then use that offset curve to do the sweep with instead of your original curve.

Similarly if you want to rotate a shape, or move it, scale it, etc..., you do all those kinds of operations to the profiles before doing the sweep, not inside the sweep command itself.

But it is kind of hard to see exactly what you want to do from your screenshot, if you are having difficulty with something could you please post the 3DM model file that you are currently working with so I could take a look at your model more directly? That may help me to understand what you are trying to do better.

- Michael

hi michael

yes your suggestion is a way to do what i want. but, sorry if i say, the workflow could be better. my intention is to select a curve from the sphere and do sweep with the rectangle profile, directly on surface, or maybe some higher or lower. with the construct/offset command i can not play around with the values. in this case i should know the distance. hope you know what i mean.

simple file below.

regards
apophis

OIC,
If you place your profile object inside the bounding area of the sweep path, it will change its behaviour. If you actually "attach" the profile to the sweep path, it will directly control the attachment of the profile to the sweep path.

But I also just re-read your last post and, this way is harder to "set" the distance value. Actually the offset the path command like Michael suggested has this function to set the value.

Hi Apophis,

Certainly for this particular case, but it is just not very practical to make a "super tool" that has every other tool all combined into it because things just get too complex with a zillion options that way.

That's why you often have to use a combination of other tools to get what you want, that helps to keep the complexity of each of those tools to a more managable level.

But actually you can - there is a "Through point" mode for offset where you can adjust the offset more freely by picking a point that it will go through rather than only specifying the exact distance.


If you want to get a more fully interact offset sweep thing going, you can use history to set that up.

Since you have a sphere you actually don't need to use offset if you don't want, you can just use Draw curve / Arc to draw in an arc path, set up a sweep on it and then use Transform/Scale to modify the arc and watch the sweep update, like this:



Just make sure not to make the sweep path get so big that the rectangle profile gets to be inside of its bounding box, because sweep will switch from "autoplace" mode into "sweep profiles from their current locations" mode when that happens.

hello

thanx for your suggestions. i didn't know that i can bind the sweep result to the curve and modify with transform- /scale or /move.
nice workflow ;-)

every day new things
