Change coordinates of a point

MichaelInneer — Tue, 14 Apr 2020 13:08:03 GMT

How can I change coordinates of a point (not move) on a line for example from x20 y30 to x10 y0? Whatever I do, it just moves for some value.

In Inventor - dimensions are your best friend (or should be).

Attach your *.ipt file here if you can't figure it out.

Hi Michael,

You can add dimensions or constraints to a point so that it is locked in the place. You an also redefine the sketch coordinate system (finish sketch -> right-click on the sketch in the browser -> Edit Sketch Coordinate -> pick a point and a linear reference to relocate the coordinate system).

Many thanks!

Thanks for reply. But I meant some option to do it directly like in 3ds max. After max it really feels uncomfortable. Inventor doesn't seem to have such a feature.

Hi Michael,

I think I know what you want now. You want to be able to redefine or move a point from A to B, right? Like I mentioned, Inventor geometry is associative. You need to use dimensions and constraints to control geometry.

Regarding move, there is indeed a way to do that too. In 2D Sketch, click on Move command -> select the point -> check "Precise Input" -> enter the X and Y movement -> select the base point.

Many thanks!

False. It is locked at specified DISTANCE from other geometry. And since there are plenty of possible solutions to it this point looks like locked only such long, as long the constraints solving system will not decide to select an another solution.

Hi Tomasz,

Indeed, to lock a point on a sketch, you will need to ground it using Fixed constraint. Outside of a sketch, it will be a grounded workpoint.

Many thanks!

Can I then enter the parametric equation for x and y coordinate and make it to follow change in parameters?

Hi Tomasz,

Unfortunately, not. A fixed point stays in the space within the sketch. There isn't any other way to move it. I guess you may want to create a grounded workpoint or UCS. A UCS can be driven by three length parameters and three angular offset parameters. It is basically grounded until the parameters change. Then you can project the UCS origin to a sketch.

Many thanks!
