WB: Image, Imageplane Image on face

Postby Petert » Sat Oct 12, 2019 11:47 am

Hi,

I am a refugee from Fusion 360, have been using Fusion for almost 4 years now and after the latest debacle with the licensing stuff I had enough of AutoDesk.
Been playing with FreeCAD 0.18 for a week now and I have some questions:

In Fusion I can use a 'decal' to put an image to a face, so labels and stickers can be shown on a model. I hoped that making a part and then selecting a face and then using the image workbench would work. But I can only select from the 'standard' planes, not my face. Even after I made a datum plane, I still do not get the option to choose that plane so the label will be in the right spot. What am I doing wrong?

I looked and looked through the documentation and could not find an answer. Maybe I am thinking the wrong way?

You can use the Part->Attachment. It will place an imageplane on some other face, but is not parametric, i.e. if the other face changes its position the imageplane will not follow.

cand this imagplane be linked to the standard face position with the new link WB

This is what happens:
Hi Peter, welcome to the forum! You're using the tool backwards. But first you should edit Sketch to make it become Fully Constrained because right now it can be moved around - its position isn't defined. You should probably apply a Symmetry Constraint to the two endpoints of either the top or bottom horizontal line segments and the vertical axis (A Horizontal Constraint will become Redundant, so look at the Solver Messages and delete it). Then apply a Vertical Distance Constraint to an endpoint of either the top or bottom horizontal line segment and the origin, or apply a Point On Edge Constraint to and endpoint of the top or bottom horizontal line segment and the horizontal axis.

Now on to using the Part WB > Attachment tool. From the history tree select your Image Plane, then click the Part WB > Attachment tool. Click the Continue button in the pop-up window to continue. When the Attachment tool widget opens, in the 3D view click the face onto which you'd like the Image Plane to be attached. Scroll down a bit and change the Attachment Mode to "XY on Plane", then click the Ok button.

I tested using your file and the version below:

OS: Ubuntu 16.04.6 LTS
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.18.1.
Build type: Release
Python version: 2.7.12
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.3.0
Locale: English/UnitedStates (en_US)

blue = edit

Wow, thank you for that!
I managed to get an image attached (kinda) to a face. But you spotted the constrain problems that caused the problems. Thanks once again!

Will try tomorrow and will let you know how it went.

You're welcome, and post back if you need more help. I spotted something in my last reply that is a bit cloudy so I'll fix that.
