constructing a plane out of coincidental planes?

[granto]

Am i wrong but i figured it would be a simple venture to take two planes that are on opposite sides of the part, called out as datum C, and construct a full connected plane? I used auto plane to scan both sides and can't figure out how to combine them?

I find it easier to make a series of auto-points, then later in the program CONSTRUCT a plane out of those points. Mainly because it is a pain in the butt to 'deconstruct' a plane (or a series of planes), then reconstruct another.

[RandomJerk]

Create a scan out of the hits of both features, then construct a plane out of the scan.

I scan both sides of the part and construct planes for each of them, then construct a width feature to be used as the datum.

[Mike Ruff]

I believe he is referring to a single plane with the middle portion missing, not two opposing planes

[BKulpa]

By his last comment on the topic I finally understand.
Duh!

[AndersI]

There's a script in the Code section for doing this - https://www.pcdmisforum.com/forum/pc...many#post32186

[davehocum]

Andersl, thank you for the code example moving features from ListBox to ListBox.

[A-machine-insp]

Taking this. Thanks AndersI . Even thought you are retiring, your DMIS legacy will live on.

[granto]

Can auto line scans be used to create a plane?

[Schrocknroll]

Can auto line scans be used to create a plane?

Select the lines, then add .HIT[1..NUMHITS] as shown in RandomJerk's example above with the planes.

I am confused on why a connected plane. For an external width (opposite planes) the datum is the center plane isn't?

[granto]

I have two co-planer surfaces on the under side of the part separated by a cutout in the center as my datum c. I was trying to take each section as auto planes and then construct a bigger plane that covers both, that didn't work. I then tried auto lines and construct a plane between them still no good. So i made freeform scans on either surface then was finally able to construct those into a full plane. Thank you for the help everyone being new im really trying to find the limits of the software. I know there are a thousand ways to do everything im PC-dmis so i have found it easier to look for the limits and stay away form these features.
