Question about project command

[idenk]

Hi, I am exploring different commands of Fusion 360 right now and really love this software.

I had a bounch of sketches imported to Fusion and wanna put them in offset plane and also align them. I am trying to use both Move command and project command to move my skech to different plane. I did meet with some problem.

Question 1.

I used move tool to put my sketch on the offset plane. However, when I paste the sketch on the offset plane, it popup in the very far position. I tried to use point to point constraint, but the two sketches will be overlap. Is there any constraint I can use for plane so that I can align the plane? Or other convient suggestions I can do?

Question 2. I also used the project command to duplicate the sketch on the offset plane. But I found out the project command is very inconvient that I have to click each segment one by one and these segment lines are fixed. I need to use "break link" command to make it editable. Also those lines are seperated after projecting. Is there a more convenient way to select the lines all together and project them and then join them to a polyline?

If you roll the timeline back to just before the sketch was created you can add an offset plane then roll back to the end off the time line right click on your sketch and use redefine sketch plane and select the offset plane you just created.

You can also use the method here to copy the contents of one sketch into another.

Hi, Mark. I tried the way you told me but two sketches still not aligned. Would you please make a screencast for this command? I would be appreciate your help.

Here's a short screen cast that demonstrates inserting a DXF then creating 2 new planes and redefining the sketch planes of 2 of the imported sketches.

Wow. This is awesome and clear. Thanks so much Mark!

Dear Mark,

Hi, I just met with another kind of stupid question.

I tried to follow this screencast https://knowledge.autodesk.com/community/screencast/4680622a-b5fa-4750-ba2f-506068a405fe

just play with the offset plane try to copy and paste the sketch to the new plane. I followed the guideline step by step, however, everytime the sketch is offset when I paste to the new plane.

like this 

But when I offset the plane from the origin YZ plane, I don't have this problem.

It is so weird because I think the first sketch was drawn on the origin plane. I offset the plane from the first sketch and this is what happened when I paste on this new plane.

Can you download the screencast software and record what you're doing. One thing to be careful with is when you offset the XY plane for example the origin of the new plane will be the document origin, if you make an offset plane from a sketch or face the origin will be at the centre of that feature. If you turn the document origin on while you edit the sketch you'll see the origins are in different places.

Hi Mark,

I think what you mentioned about the center point makes sense to me. But I still cannot feagure it out. Shall I reset the center point?

I did the screencast and the link is right here https://knowledge.autodesk.com/community/screencast/15537765-187f-4030-8655-db6ffdf86f8e

I offset the plane from the sketch and also YZ plane. The second offset plane works but the first one still doesn't.

Thanks so much for helping me with these fundamental problems.

At about the 40 sec mark in your screencast just after the first paste if you were to make the document origin visible you would see it's in a different place than the sketch origin.

I think the document origin is the white point.

There's no way around the rule that a plane created from a surface or sketch will have it's origin at the centre of the feature. As an easy example draw a circle at 10,10 on the XY plane, create a offset plane using the circle profile, create a sketch on the new plane and it's origin will be the centre of the circle, like this.

If you were to copy the original circle and paste into the second sketch it will be at 10,10 in the new sketch and 20,20 looking at the document origin.

Your only option will be to project a point from the original sketch then paste and use the point to point option on the move dialog.

Thanks Mark. Now I Understand it.
