Create a surface using multiple curves

Hello,

I have an electronic board on which I'm trying to create a surface across all the pads. I can with the projection tool into the sketch but this is very tedious.

I did it on 3 pads to give you an idea, but the surface should be present on all the grey pads. This surface will be use in creo machining for programming a laser machine in order to clean the pads.

I try to create a section then a curve from it but I can't fill in the curve...

Do you have any ideas ?

Thanks in advance

Hi,

assumption: all pads have some height dimension ... let's say 1 mm

Steps to follow:

1.] in assembly create planar x-section X1 parallel with top face of green desk with distance 0.5 mm

2.] create Curve from Cross Section and select X1 ... you will get single curve containing outlines of all pads

3.] create Fill surface in some plane parallel with top face of green desk

4.] select single line from curve defined in 2.

5.] edit chain properties of selection

6.] select all curves using following setting

7.] finish the feature
