Create from segments does not work as wanted

Hello,

Last week I've been busy practicing with QCAD.
Most of the functionality works fine and I understand how to use.

What I can get working properly is the create from segments option.
I made an example drawing from a curve created from 2 eliptical parts:

I can't get these two curves connected no mather what I tried.

Hope anyone can help me.

Thanks in advance.
Best regards, Eric.

p.s. I'm using version 2.2.2.1

"Create from segments" creates a polyline from existing line and arc segments. Polylines in QCAD cannot (by definition) contain elliptical segments since this is not supported by the DXF format.

You may want to group them into a block instead to create one entity.

Hello Andrew,

The reason it doesn't work is clear for me right now.
I have to use blocks for this in the future.

There isn't a simple group/ungroup function in this (or a later) version?
It's much work to create blocks for everything you would like to put together for a few moments so it can be selected with one click of the mouse.
(I haven't found an unblock function)

Best regards,
Eric.

There are only two major differences between blocks and what is called "groups" in other drawing programs:
1. Blocks have a name, groups don't
2. Blocks can be inserted more than once (at different scales, angles, etc.)

To use blocks like groups, proceed as follows:
- ignore the fact that blocks have a name
- use "Block" - "Create Block" to create a new block from the selected entities (i.e. to group the selected entities)

Use "Block" - "Explode".
