How to use "3d Constraint" command within Freestyle workbench in Catia?
I read Catia's documentation, however I got my answer in wording but the given examples didn't give a notion for my question. Examples are for 3D objects.
What I am looking for is, when a put a 7 degree curve between two geometries in 3D space, I want to apply G2 / G3 continuity to my profile curve, like we apply constraints in sketcher. If I can manage that it would be amazing. I tried a lot and made a research but had nothing reasonable yet.
Thanks in advance,
"If I use a plane and use curvature continuity it corresponds to G2, right??"
Sorry no! G1, G2 and G3 is the quality how TWO curves or surfaces fit togehter.
I have two more ideas for your problem:
1. Draw a line between the points, make five "Points and Planes Repetions" at the line, use these points for the 3D-curve (example above)
2. Use "Blend curve", you can choose G1-G3 at both ends and also can model the shape with the tension icon.
Hope this is workes.
I hope, this is what you are looking for...
I made two random curves.
Then using 3D-Curve Icon clicking at the first point of curve one.
You need five points between to get G3 at both sides.
The sevens point is of curve two.
At both ends POINT is appearing.
Right mouse click at point --> choose the continuity.
Thank you for your time. Unfortunately I couldn't make it.
I tried it as you said, but couldn't make it. If I have to click five points in the space than it won't do good for making a clear curve.
I thought that when we define control point number in the 3D Curve dialog box, Catia puts defined number of CVs between the two points we indicate as start and end points of our curve
For example, like connecting the wing with the fuselage. We may need some profile curves connecting two bodies in different coordinates. That is why I asked this question.
What I was doing is first clicking the end point of the first curve then the second end point of the second curve. Then looking constraint options!
I go to "Matching Constraint" command in order to have the curves in the desired continuity levels. But I couldn't manage to control this command properly as well.
Here are the screenshot of what I have done.
My reply could be confusing, here attached a screenshot of my Mirage 2000 model made within solidworks. I considered my self making the blue section indicated in the picture in Catia.
In the blue area, the combining curves are visible. My question was about making them as 3d curves in order to have G3 continuity. If I use a plane and use curvature continuity it corresponds to G2, right??
Thanks in advance,
