How to straighten Plane 4 and Sketch 5

craig_sosebee

I can easily create an angle off of a flat side of the square, but when I create one off of the corner of a square the plane is always skewed and thus the rectangle I want for a loft is also skewed.
In the picture you can see that Plane 1 and 3 are square to the corner, but plane 4 comes out as skewed. I can do this off any of the faces of the square and it will all be square to that face, but it doesn't seem to work when trying it on the corner of the square. I'm guessing there is a better way to do this? To clarify, I'm looking for Plane 4 and the square in sketch 5 to be straight on like Plane 1 and Plane 3. Here is the link to the public file:

Thanks for any help!

Use a mate connector instead of a plane - you have full control over axis orientation. MCs can be used anywhere a plane can.

This document has a very useful custom mate connector

Using MultiMateConnector (MMC), It’s hard for me to make a three point plane.

I can get the center point of the MMC on plane with the three points.

But I haven’t figured out how to get the main axis (Z) of the MMC normal to those three points yet.

I could approximate the NORMAL TO aspect. But that’s about the best I could do at this point.

So there’s one reason for using the Plane tool.  SEE POST BELOW

And I think there are other reasons for using Plane. For instance — doing an offset with the Plane tool is pretty fast.

Thought came to mind a little while ago. Tried it and sure enough, found out MultiMateConnector is ALSO CAPABLE of doing 3 Point Planes. AMAZING TOOL MultiMateConnector is !!

As Neil said, mate connectors are the way to go, here's a practical example of how it could look like:



I added one line to sketch 3 to provide a normal to pick for the sketch 5 mate connector. Note I still had to "realign" the secondary axis for the rectangle to be "straight".

So is there now any reason to use the new plane button over a mate connector?

WOW. I asked this question and the answers just kept getting better and better. What a fantastic support forum! This example is above and beyond what I needed. Thanks!
