Sketch Planes - Help

[Anonymous]

I'm a new user, and want to maintain origin axis and plane orientations as always centered to my primary sketch geometry. Usually done by dimensioning (calculated as half the overal width) from an edge to the plane. Consequently, when editing the overall width, the plane remains in the center of say an extruded feature. How do I do this in Inventor ?

If I understand correctly you would like to extrude equally on both sides of the plane, ie a "Midplane" extrusion. This should be the third box on the right under the extrusion length with arrows pointing in two directions.

See pic.

Actually, I want the Sketch Geometry, say a rectangle, to always be centered on one or both planes perpendicular to the sketch plane. Then when I extrude midplane, the solid is centered on the intersection of all the planes (origin).
Coming from solidworks, it was possible to dimension to any plane in a sketch, haven't seen that capability yet with inventor.

Use the Project Geometry command to project the origin point into your
sketch. Than you can use this projected point for constraints and
dimensions.

Vertical and horizontal constraints between the origin and relevant
mid-points (you only need one of each). Whether you dim it or not it will
stay centered.

No time warp, Larry.

Umm ... email ... where did you send it? You send it to my insightbb email
or to my houston.rr email? Guess I'll still be in KY for awhile they want me
to stay at least to the end of this project. They will'n to pay I'm will'n
to stay, I guess, so use the insightbb address as seen below with the X's.

I used the insightbb email and didn't get a bounce reply. So it arrived
anywhere ... maybe it's just another blacklist glitch. I sent you three test
mails right now from different accounts. Did you get them?

Yep ... got all three ... two of'em went to the Qurb quarantine but there in

Whew......
project origin ? horizontal constraint of midpoint...eek
Haven't figured that out yet, and the video wont run on this network computer.

Guess I will have to do some reading.

Thanks for your help though.

I model in Inventor exactly like SWX except that you have to Project Geometry (convert entities) yourself. Expand the origin folder in the browser and while in sketch select Project
Geometry and then the CenterPoint. You should be able to figure it out from there.
A couple of other things I do to get Inventor to work more like
SWX is Tool>>Application Options>>Sketch turn off the grid (haven't used a grid since my second CAD class back in '87 or '88) and turn on Edit Dimension when created. I also turn off Autoproject edges on new sketch (I prefer to select what edges or points I want to project (convert entities in SWX terms).

[Anonymous]

Oh sweet "convert entities"......ahhhh, I can sleep tonight.

Thanks to all !, and for your description JD.

Read up on the "Project Geometry" and "Constraints" commands / icons.

Attached is a part like I think you want.

Kent Video shows it the best, but here is what is done.

In the sketch, as mentioned project the centerpoint (origin). This will allow you to constrain to the point. Create a rectangle, and then draw a diagonal Construction line from corner to corner. Constrain the midpoint of the construction line to the centerpoint. The the constrain tool on and set to "Coincident," when you hover over the construction line near the middle you will see a green dot. Click it and then the center point. Then those two points are constrained. Dimension the rectangle as desired or you can use the "Equal" constraint to make a perpendicular edges equal.

Note: I sketch with the default set to horizontal and vertical constraints on lines vs perpendicular and parallel. You may need to add a horizontal or vertical constraint to keep the box from rotating.
